TRP’s No-Ream King Pin Kits are manufactured using high-quality steel and modern heat treatment and machine tool technology. The kits are available in multiple diameter lengths for many makes of trucks and buses and include spiral bushings engineered with deeper grease grooves to allow more grease in high wear areas. They also are designed to make repairing front-steering axles more efficient by eliminating the need to ream the king pin bushings after installing them in the steer knuckle.
