4x2mm & 4x2.5mm BASE Kingpin bushings for ALL Spring Trucks
These NYLON Kingpin bushings are Housed within the holes of the Baseplate & Hanger
The bushings allow the kingpin to move freely when the Truck is constructed.
Made with slightly different thickness base's which helps to bridge any tolerance issues in the construction of the truck. These special Nylon Bushings are produced using Food Industry Standard materials (the best possible!) & ensure maximum durability.
A little spray of WD40 will help the kingpin glide through the bushings and truck parts holding everything in position....
To maintain maximum performance of your equipment check these bushings on a regular basis and replace them if the look tired or worn out
