The new line of TRP No-Ream King Pin Kits are manufactured using high-quality steel and heat treatment and machine tool technology, according to TRP Parts. The kits are available in multiple-diameter lengths, and are designed to fit many makes of buses and trucks. The kits include spiral bushings with deeper grease grooves, created to allow 25% more grease in high-wear areas.
The new kits can also make repairing front-steering axles more efficient. There is no need to ream the king pin bushings after installing them in the steer knuckle, which can save on labor and repair time. Additionally, the use of reamers, presses, and pressing-in bushings during installation is no longer necessary, according to TRP. The kits are backed by a one-year or 100,000-mile warranty.
