Summit Racing™ Cummins Retrofit Trunnion Kits
Summit Racing™ Cummins retrofit trunnion kits are designed to help eliminate rocker body wear by converting the trunnion to a bushed-style assembly. The trunnions are manufactured from micro-polished hardened steel, and the bushings are made from bearing bronze. Oil-flow channels are machined in the trunnions to ensure adequate lubrication to the bushings. For diesel power and performance, upgrade to a Summit Racing™ retrofit trunnion kit.
