Overview

The Rocker Arm Trunnion Set is an upgrade for an often overlooked oem part in modified trucks. The oem rocker arm trunnions were only made to withstand stock horsepower levels and the additional stress caused by common performance upgrades can quickly push these levels above what they were designed to handle. When this happens, it can cause galling on the trunnions and the rocker arm bushing surfaces, once the galling begins it often ends with the rocker arm seizing to the trunnion causing severe engine damage.

XDP's Rocker Arm Trunnions are designed for enhanced oil flow to eliminate these issues. Manufactured with larger oil supply holes, increased oil groove width and additional oil transfer grooves that reduce friction in the rocker arm bushing area to extend the life of both the rocker arm and the trunnion. The set is cnc machined from premium tool steel. They are core hardened, precision ground and nitrided, these extra steps in manufacturing provide increased durability and an extended life. Each set includes a refinishing kit so you can polish the galled rocker arm surfaces before installing.
