The king pin is the most critical component on the steer axle, so the correct king pin must be specified and technicians must be trained on safe installation. STEMCO KAISER offers the broadest coverage of king pin kits with over 250 options including 100 different QwikKit applications. We also have full coverage with our Plus Kit™ and ECONO KIT. In markets that require a bronze bushing, STEMCO offers the STEMCO KAISER Plus Kit. With pre-sized bi-metal bronze bushings, this kit quickly becomes the alternative to a reamed king pin installation. Reamed installations are still achievable with the STEMCO KAISER ECONO Kit king pin and bushing kit.
