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 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...
One way to check your bushings is to man handle the truck... If you feel any play then you definitely need to replace the bushings before you do damage to the hanger. Worn out Bushings will cause the kingpin to run in the Hanger kingpin hole... The kingpin is stronger than the Ali used to make the hanger and the kingpin will wear a nasty hole of you do not fix the problem before it gets too late.
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.

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.
