TRAMPA's INFINITY TRUCKS offer the rider the strongest, the most beautiful & the most adjustable steering ever to hit the hills of Mountain Boarding!

The INFINITY HANGER is the strongest SPRING TRUCK Hanger in the TRAMPA product range! To ensure the maximum strength possible the hanger body is made from FORGED ALUMINUM and is one solid piece with no fancy weight saving holes! The Infinity Hanger is drilled & fitted with 12mm SOLID STEEL Axles. The Axles are HEAT TREATED. Heat treating steel makes it substantially stronger & more resistant to impact. 12mm Solid Steel Axles are slightly heavier than alternatives displayed on the TRAMPA website, but they are by far the strongest Axles in the TRAMPA range. CNC milling guarantees precision work. Ensuring the Kingpin Holes are accurately placed guarantee's the best performance to the rider as well as making the truck easy to assembly & service. The Infinity Hanger is EDP painted MATT BLACK for metal protection & colour coordinating good looks before the CNC work is carried out. The INFINITY hanger measures 16 Inches in total width. When the wheels are fitted to the Hanger, the board has a center wheel width of 15 Inches.

EXTRUDED & HEAT TREATED T6 Aluminum for the BASEPLATE - as its name suggests the TRAMPA INFINITY TRUCK was designed to last for forever!!  The Hanger & Baseplate "Kingpin Holes" are CNC precision milled, allowing the Truck to assemble like a dream - everything fixes together perfectly! An 8mm STEEL KINGPIN fitted with Nylon Bushings seriously reduces weight (comparing to MBS or SCRUB) & perfectly connects the 2 integral parts together, allowing the steering to happen...

Using pre-tensioned SPRINGS to stiffen the steering, TRAMPA TRUCKS provide smooth, precise & problem free riding. They come loaded with FULLY ADJUSTABLE STEERING which means that by using a 4mm Allen Key you can TUNE your steering on the fly! Turning the SPRING ADJUSTER clockwise for TIGHTER STEERING (fast riding) & anti clockwise for LOOSE STEERING (Carve style riding), you can setup your board relevant to the conditions & terrain ahead... Its your choice of TRAMPA DAMPA! Selecting the correct DAMPA will further pre-tune the steering to your weight, riding ability & personal preference... As you improve as a rider, you will demand more pre-tension from your steering, this can be achieved by changing / stiffening-up your Dampa. DAMPA's come in 5 different hardness's & are cheap to purchase. When fitting them to the TRAMPA Trucks they very easy & quick to exchange. Perfectly formed SPRING RETAINERS, are re-enforced with Stainless Steel inserts (which means no fiddley washers are needed to be fitted (unlike MBS or SCRUB) making changing your DAMPA's very easy to do) hold the DAMPA, within the spring, in the absolute perfect position!

18.2mm spacers position the Wheels on the 12mm axles in the perfect location & 7/16ths of an Inch MGSS Half nuts stop the wheels working loose and as with all TRAMPA products these INFINITY Trucks use Marine Grade Stainless steel Hardware (MGSS) to fix them to a TRAMPA deck.

The INFINITY TRUCKS are the perfect option for all BEGINNER RIDERS who want the best equipment but are on a budget, LARGER ADULT SIZED riders looking for bomb-proof equipment & the totally insane riders who want to go bigger than all the others!

Having been made by extrusion technique the BASEPLATE is all one solid piece of aluminum. The KINGPIN holes have been CNC machined which means the kingpin hole is neither too tight or baggy, ensuring super smooth & balanced steering supported by the Springs & Dampa's.

By using an 8mm Kingpin serious amounts of weight have been saved compared to our competition. The light weight plastic bushing which the kingpin operates within, not only further saves weight but ensures a tight & accurate, smooth steering. These Trucks really have been precisely made & you can feel the difference in the ride.

The INFINITY truck system also has a steering adjustment facility. You can alter the resistance of the steering relative to your body weight and personal requirements by simply turning the "SPRING ADJUSTER". By inserting a 4mm Allen Key & turning the Spring Adjuster "clockwise", down onto the DAMPA, increases the resistance of the steering. This will allow the rider to achieve higher top end speeds without so much speed wobble. The rider can fit different DAMPA's in different corners of the deck to custom the steering of their board exactly the way they need it. To make your ride more personal the Spring Adjusters can each be tweaked differently giving you the custom ride your looking for, soft on the toes, stiff on the heels, or loose at the front but stiff at the rear.... the options are endless.... Generally speaking if you want to achieve high speeds you will need tight steering resistance otherwise speed wobble is possible, loose trucks are great for carve riding & gentle slopes.... These Trucks come as standard with YELLOW TRAMPA DAMPA's as these are the softest & easiest to steer with but you can select a harder compound if you so desire. They are housed within the Spring & kept in the correct position by a specially made re-enforced spring retainer.

The re-enforced plastic injected Spring Retainer is made from original DUPONT material. Even though its under a lot of pressure it retains its shape very well giving maximum performance to the TRAMPA DAMPA. It house's a specially made Marine grade stainless steel FLANGED WASHER which is located into the mould before the material is injected. This re-enforced custom piece eliminates the need for a stupid Penny washer (which is used by the other brands to support their cheap spring retainer & is a complete pain in the XXXXXX XXX to fit) and consequently our special little piece gives the rider easy access to servicing the springs or changing the Dampa's as fitting the springs back into the TRAMPA Trucks is now very easy as the TRAMPA Spring arrangement can be fitted done by hand by one person with just 1 basic tool to tighten everything up...  Hallelujah!

The Spring Adjuster is also a very special part as it has been custom made from Marine Grade Stainless Steel & it will not rust on you. It has been designed to improve the riding experience & is to be used as an indicator telling you when you are over tightening the adjuster as the length of the adjuster has be shortened at both ends (compared to the competition) and so does not to poke through the SPRING RETAINER therefore doesn't interfere with the DAMPA below & nor does it stand proud of the deck exposing itself as a blunt edge, eliminating any associated danger implications. Also the neck of the adjuster (the area which sits within the retainer) has been narrowed so that it fits within the thread of the Spring Retainer effectively giving the rider 4 spare Spring Retainers should they ever need one in the future. By turning the Spring Adjuster "clockwise" down onto the Dampa, increases the resistance in the steering. This will allow the rider to achieve higher top end speeds without so much speed wobble. The rider can fit different DAMPA's in different corners of the deck to customise the steering of their board exactly the way they need it - GENIOUS!

To gain the maximum performance when riding the assembly between the Baseplate & the Hanger needs to be the best it can be. So in order to gain accuracy in construction the Kingpin holes for both the Baseplate & the Hanger are CNC'd. These precision hole's then house the Nylon KINGPIN BUSHINGS which in turn allow the Kingpin to push in & fit perfectly through the assembly. In order to cover the issue of tolerance we created 2 types of Kingpin Bushings to ensure the kingpin fits the engineered truck parts correctly. The only difference between the bushings is 0.5mm thickness at the base. Each truck has 4 bushings so this gives us an overall difference/tollerance possibility of 2mm in thickness (if all 4 bushings are used) so we bridge any tolerance issues we face during construction.

The spacer for the axle is the same size (18.2mm)  as the spacer in between the bearings making everything nice & easy when servicing or maintaining your deck.

The INFINITY TRUCK is also available with a SILVER BASEPLATE.

The INFINITY TRUCKS are also available with MAGURA BRAKES

M5 x 12mm Countersunk Allen-Key Bolt - Marine Grade Stainless steel with locking paste

Made from A4 Marine Grade Stainless Steel, all of the nuts, bolts & screws used in a TRAMPA board have proven to be up to the challenge of holding everything together. Using Marine Grade Stainless Steel also means these Bolts will never rust on you! They can cope with the harshest of weather conditions & will laugh in the face of sandy/salty beaches or muddy freeride tracks - which can turn other manufacturers’ nuts & bolts into corroded rusting wrecks!

Wherever possible, we dip all our bolts into BLUE THREAD LOCKING PASTE, to ensure an extra strong & secure fix between the nuts & bolts.

The head of this Bolt is COUNTERSUNK, meaning that when screwed into position it sits flush & neat with the surface its screwed into. Preventing bolts from standing proud eliminates the chance of anything getting "snagged or hung-up" should it get caught on something..

Used For;

-Ratchet Bindings

-Camlock Bindings

-Heelstraps

M6 Nut - Marine Grade Stainless steel Nylock Nut - Fixes Bindings & Trucks to Deck

Introducing TRAMPA's M6 (6mm Thread) A4 Grade Marine Grade Stainless steel Nylock Nut. This Nylock Nut will fit to all M6 Bolts regardless of their length. This A4 Marine Grade Stainless Steel Nut will never rust on you! It is fitted with the world renowned NYLOCK System (Nylock is a nylon locking system where Nylon is pasted into the threads of the nut so that when the bolt is tightened into the nut the nylon grabs the thread of the bolt holding it locking it in the thread ensuring things do not vibrate loose or fall off when being ridden on rough terrain like that which a Mountain or Kiteboard endures. The NYLOCK System is fitted as standard to all TRAMPA Nuts. 

This Nut is used to fix to the Regular shaped M6 Bolts that hold the TRUCKS to the DECK for the HOLYPRO Decks & also for the countersunk bolts connecting the L BRACKETS TO the DECKs. Use an 10mm spanner or SOCKET for a Ratchet Driver to tighten the Nut onto the Bolt. Always ensure your Nuts & Bolts are tight before you ride!

7/16ths Nut - Marine Grade Stainless steel Nylock Axle HALF nut (W7/16-20T UNF) - Fits to 12mm Axles

This very special 7/16_^ths of an inch Marine Grade Stainless steel Nyloc HALF NUT is custom made specially to fit the TRAMPA products. Half nut means - half as the size of a regular nut, so half the size = half the weight of a normal nut.. By using Half nuts on the axles reduces the over all length of the axle & kingpin therefore further reducing weight in the Truck! A few Grams here & a few grams there soon adds up & makes all the difference to the total Truck & consequently deck weight, specially in critical areas of the deck such as the wheels area, where a few grams makes all the difference...

This very special 3/8_^ths of an inch Marine Grade Stainless steel Nylock Half Nut official factory measurements are  W7/16 - 20T - UNF. This Nut is used to hold the wheels onto the axles of the Spring Trucks fitted with 12mm axles. The Nut is fitted as standard with the world renowned NYLOC System. The Nyloc "locks the Nut onto the Bolt" eliminating vibration, keeping your nuts tighter for longer!

Use a 16mm or 5/8th_^ths of an Inch spanner to tighten / loosen the Nut onto the Axle or Kingpin. Do not overtighten the nut & make sure the wheel can spin freely but does not rattle & do not crush your bearings. Being Marine Grade Stainless Steel this nut will not rust you! Always ensure all ur nuts are tight before you ride!

Wheel support spacer for all TRAMPA Wheels on 12mm ATB Axles - CNC precision 12mm x 16mm x 18.2mm - CUSTOM

This special Spacer measures 12mm (id) x 16mm (od) x 18.2mm (long) & has 2 uses!. It is firstly known as the Bearing Support Spacer as this Spacer fits between the Bearings of a 6 Spoked HYPA Hub, (when mounting the HYPA wheel onto 12mm Axles) & secondly it is also known as the AXLE SUPPORT SPACER as this spacer is also used to position any of the TRAMPA wheels in the perfect position onto the axles of 12mm TRAMPA Spring trucks....

TRAMPA spacers are produced as one long tube. The Tube is Heat Treated to gain extra strength & is then Bead Polished to give the metal extra surface protection & a shiny best appearance. The tube is then cut to the exact length for precision mounting. 

CUSTOM Spring Truck Baseplate - Extruded T6 Aluminum Anodised & CNC precision Milled

The  INFINITY Baseplate will fit to all of the TRAMPA Spring Truck Hangers but is designed specifically to work in conjunction with the Mini Spring Hanger as it houses a NEW Dual Spring Adjuster position! When the Springs are moved to the new inside position, the new location allows the rider to turn the board very very easily, making it perfect for fast carve riding on all kinds of terrain. You can see the new & growing TRAMPA STREET CARVER range of products here...

The  INFINITY Baseplate is, as its name suggests, designed & built to last forever! Aircraft grade 6061 Aluminum is forced through a Die to create our re-enforced extruded profile. Extruding Aluminum ensures consistent high quality strength. Once Extruded the Baseplate is T6 Heat Treated. Heat treating extruded aluminum fuses the molecules even closer together making it as strong as possible, enabling the INFINITY Baseplate to easily cope with the extreme stresses of all types of off road boarding.

Once Heat Treated, the profile has its fixing holes punched into position & then its Bead Polished in preparation to be Anodised Silver. Once the colour has dried, the Baseplate is then returned to the factory for the precision CNC Machine to accurately mill the Kingpin holes, giving the exact precision required for constructing the Truck.

INFINITY ATB Hanger - 12mm SOLID Axles Painted Black & CNC'd Kingpin hole

The ATB INFINITY HANGER is time proven as being the strongest ATB SPRING TRUCK Hanger on the market! Ensuring we deliver the maximum strength possible the hanger body of all of the Spring Trucks in the TRAMPA range are made from super strong FORGED ALUMINUM & this INFINITY hanger is one solid entity with no weight saving cut outs or or fancy Axels & weighs in as the Strongest!

The Infinity Hanger is machined on the underside to allow countersunk bolts to push through & position the springs in the correct locations. The Infinity ATB Trucks has been given 2 Spring position settings, allowing Inside spring position setting for easy/fast carve steering & outside spring position for larger sized or high speed thrill seeker riders!

The Infinity ATB Hanger is drilled & machine fitted with Heat Treated 12mm SOLID STEEL Axles. HEAT TREATING the steel axles makes them substantially stronger & far more resistant to impact - perfect for larger sized adult riders. 12mm Solid Steel Axles are slightly heavier than alternatives displayed on the TRAMPA website, but they are by far the strongest Axles in the TRAMPA range. Once the 12mm Solid Axles are machine fitted the INFINITY hanger measures 16 Inches at its widest points & when any of the 5, 6, 7 or even 8 Inch HYPA or SUPERSTAR wheels are fitted to the Hanger, the board has a center wheel base width (Center point of contact to the floor) of 14 Inches.

CNC milling usually guarantees precision work & that's why the Infinity hanger has had the Kingpin holes CNC machined insuring the Kingpin Holes are accurately placed guarantee's the best performance to the rider as well as making the truck easy to assembly & simple to service. Before the CNC work is completed the ATB Infinity Hanger is Anodised BLACK for metal protection.

Custom Kingpin for Spring Trucks - M8x80mm Nikle Plated, Stainless Steel or TITANIUM

This 'M8 x 80mm Spring Truck Kingpin' is used to connect the Hanger & the Baseplate on any of TRAMPA's Spring Trucks.

Using high quality metals & sizing down to a 8mm Kingpin, we have managed to save loads of weight whilst retaining all the strength necessary for the job!

This M8 x 80mm Kingpin uses an 8mm Washer to support the busing from the outside & a 6mm washer to protect the bushing on the inside side & connects into an M6 Nut. You'll need a 4mm Allen key to hold the Kingpin & a 10mm spanner to tighten/loosen your M6 Kingpin Nut.

This Kingpin pushes through plastic bushings before being placed into position in the Truck System. The Plastic bushings allow the metal parts (Hanger & Baseplate) to move freely inside each other without allowing the metal parts to touch or wear out.

The plastic bushings will wear out over time & use & will eventually perish & need replacing. SO, make sure your Bushings are always in good working order after riding riding or when upgrading your Kingpin, it might be time to replace them too due to the unavoidable wear & tear of moving mountainboard parts.

King Pin Bushings have different thickness bases & fit into all Spring Trucks

The 2mm Kingpin Bushings are pushed into the holes of the SAVAGE Hanger & sit tightly in position. They hold the Kingpin in a wear-free position between the moving metal parts of the SAVAGE hanger & Baseplate.

The Bushings allow the movement (steering) without wearing out the metal parts.

The Kingpin bushings are a small perishable item. They are subjected to a lot of forces & stress, although they are now supported by a 2mm Kingpin Bushing re-enforcement ring, through regular abuse they will ultimately wear out & eventually need replacing.

Depending on what surface you are riding on & the nature of your riding style will depend on how long these bushings will last you.

To make sure your trucks are always performing at their best you should keep some spare Bushings on the shelf at home & inspect these them on a regular basis (preferably before riding) & in particular replace any bushings that are showing signs of wear & then even if they are not broken from time to time replace them anyway...

One way to check your bushings is to man h&le the truck when fitted to the deck... If you feel any play between the Hanger & the Baseplate then you definitely need to replace the bushings straight away before you do damage to the hanger.

Worn out Bushings will cause the kingpin to rub in the Hanger kingpin hole... The kingpin is much stronger than the Aluminium used to make the hanger & the kingpin will wear a nasty hole of you do not fix the problem before it gets too late.

If you ride with trucks that have play in them, then you are lining yourself up for an accident... If you feel any play, this can at speed convert to wobble & we all know riding with a board with a wobble will lead to accidents, so it is wise to check your bushings & rings on a regular basis.

The difference between the four bushings is the thickness of the base. The different base sizes are 1mm, 1.5mm, 2mm and 2.5mm. 2.5mm is the standard size we work to. As all trucks have 4 bushings this .5mm difference in each of the bushing bases allows us to bridge a maximum distance of 2mm (4x.05mm=2m) resolving any foreseeable problems.

Kingpin Bushings 3mm Base - for Spring Trucks

The Kingpin Bushings sit tightly in position & hold the Kingpin in a wear-free position between the moving metal parts of the hanger & Baseplate. The Bushings allow the movement (steering) without wearing out the metal parts. The Kingpin bushings are a small item & are subjected to a lot of forces & stress, through regular use they will ultimately wear out & need replacing. Depending on what surface you are riding on & the nature of your riding style will depend on how long these bushings will last you.

To make sure your trucks are always performing at their best you should keep some spare on the shelf at home & inspect these tiny bushings regular basis (preferably before riding) & in particular replace any that are showing signs of wear & then even if they are not broken from time to time replace them anyway...

Kingpin Bushing Re-enforcement Ring - Custom

2.5mm Kingpin Bushing Re-enforcement Rings are used in the assembly of all of the TRAMPA Spring Trucks with EXCETION TO the SAVAGE Trucks which use 2mm Kingpin Bishings & 2mm re-enforcement rings in its assembly.

The Kingpin Bushing Re-enforcement Ring is pushed onto or over the top of the Kingpin bushing after it has been inserted into the Hanger & before the baseplate is presented for connection.

The Re-enforcement ring spreads the weight of the connection to give extra support to the tiny kingpin bushings, whilst still allowing the free movement between the Hanger & Baseplate (steering), without wearing out the metal parts.

The Kingpin bushings are a small perishable item. They are subjected to a lot of forces & stress, although they are now supported by the Kingpin Bushing re-enforcement rings, through regular abuse the bushings will ultimately wear out & eventually need replacing.

Depending on what surface you are riding on & the nature of your riding style will depend on how long your Kingpin bushings will last you, regular service will prolongue their life but they should be replaced when possible.

As all the metal parts are hand constructed here in the UK, so it has been easy for us to control the construction of the Trucks to ensure each truck that leaves the building has the correct size bushings fitted & therefore we can ensure totally smooth steering system in every Truck like we always brag about :-)

Custom Colour Spring - Powdercoated Sprung Steel Steering Springs

TRAMPA's SPRINGS are coiled to precision & fit into the TRAMPA Spring Trucks perfectly. They easily squeeze into the space between the Baseplate & Hanger & being made to measure they are firstly very easy to fit with no clamps or tools required to squueze them into position & secondly to be super responsive to the rider.!  Once the spring assembly is fitted correctly the steering resistance is taken up instantly!

Our Springs have been designed to work in perfect harmony with the TRAMPA DAMPA's & TRAMPA SPRING RETAINER providing maximum performance from the "Spring assembly" to the rider. The DAMPA's drop into the SPRING & the SPRING RETAINERS seal the ends of the spring, holding the DAMPA in exact position to be pre-loaded & squeezed into the truck. Using just a little bit of muscle, squeeze the loaded spring into the truck, then lock the spring into position using the Spring Adjuster & M5 x 12mm Countersunk Bolt. The TRAMPA spring Truck steering system is highly responsive & totally customisable by interchanging the DAMPA's to harder Urethane. Other Mountain Board brands springs will not fit the TRAMPA Trucks as they are a different in dimension.

TRAMPA Springs are available in a selection of Powder-coated colours for good looks & of course for best surface coating protection & this one comes to you in Powder Coated Black. 

Spring Retainer - Specially designed to work in harmony with the Dampa & spring

TRAMPA's very own & very special re-enforced Spring retainer. Specifically shaped to fit tightly inside the TRAMPA springs & snugly hold the Trampa Dampa in the exact position to give precision steering to the rider. Made by Injection Moulding using original Dupont Materials, with an extra wide Marine-Grade Stainless Steel Flanged Insert seated internally, re-enforcing the Retainer. The Extra Strength of the re-enforced flange, eliminates the need for a very fiddly fitting washer, that is still found in the MBS and Scrub boards today.

Designed to work in harmony with the TRAMPA spring and TRAMPA Dampa to help create immediate resistance from your steering system. With TRAMPA Embossed around the rim of the retainer - you'll have performance with pimpness!

The TRAMPA DAMPA is a Urethane Elastomer that fits inside the Spring of a Truck. Its purpose is to support the Spring & give extra resistance during steering. Its clever design has three balls stacked & connected on-top of each other. The middle ball is slightly fatter than the outer two, during steering they all compress against each other giving greater feed back in your turns. This stacked design gives a fantastic progressive feel to steering.

By varying the SHORE DUROMETER (Rubber Hardness) strength of the Urethane mixture, we can control the amount of movement in the DAMPA. This in turn allows the rider to custom tune the resistance of their steering perfect to their requirements. The spheres of the DAMPA fit perfectly into the cup of the specially made TRAMPA SPRING RETAINER which is the part that locates & locks the Spring in the the TRAMPA SPRING TRUCKS, and they instantly start to work with the slightest movement from the rider. TRAMPA DAMPA's work in harmony with the rider, supplying the perfect amount of steering resistance whilst eliminating all chances of speed wobble. Now available in 5 different steering resistance's for all levels of rider out there, Orange DAMPA's are for easy steering, whilst White DAMPA's are for the totally committed! 

Turning the Spring Adjuster clockwise pre-loads the tension in the Spring and DAMPA. This can be adjusted on the fly to suit the terrain & conditions. Turning the spring adjuster too much will put pressure on the DAMPA & eventually it may split. Rather than putting too much pressure into the DAMPA, consider up-grading the DAMPA to a harder Shore Durometer as this will most likely increase your performance than over tightening a DAMPA that's not stiff enough for you. Please use the table below for guide.

Spring Adjuster - Marine Grade Stainless Steel

TRAMPA's very own & very special SPRING ADJUSTER is made using A4 MARINE GRADE STAINLESS STEEL & is guaranteed never to rust on you! The Spring adjuster is fitted to the trucks once the springs have been pushed into position. The spring adjuster pre-tensions the steering suitable for the rider’s requirements. We designed the Spring Adjuster to be slightly shorter in length than other brands’, to avoid  the tip of the adjuster poking through the internal of the Spring Retainer, and interfering with the performance of the DAMPA located on the inside of the Retainer.

Should you need extra resistance from your steering because you wish to ride fast, or if you need more steering because the course is twisty, then you can very easily & quickly adjust the resistance of your steering by simply turning the spring adjuster in the correct direction. To get the most out of your trucks on changeable terrain, simply use a 4mm Allen Key to make your adjustments. Winding the Spring Adjuster clockwise increases the steering resistance, which in turn restricts wobble at high speed. Turning the Adjuster anti-clockwise loosens the steering allowing a more carvey ride.  

DO NOT over tighten your Spring Adjuster, as this may crush your DAMPA. If you need more steering resistance upgrade your DAMPA's & do not over tighten!
