1998.5-2018 DODGE RAM 5.9L/6.7L CUMMINS

The XDP Rocker Arm Trunnion Set With Polishing Tool XD319 is an upgrade for the often overlooked rocker arm trunnions in modified 1998.5-2018 Dodge 5.9L & 6.7L Cummins engines. The OEM rocker arm trunnions were only made to withstand stock horsepower levels. The additional stress caused by common performance upgrades can quickly push these levels above what the factory components were designed to handle. This causes galling on the trunnions and the rocker arm bushing surfaces. Once this galling begins, it often ends with the rocker arm seizing to the trunnion causing bent pushrods and in many cases severe engine damage. 

The XDP Rocker Arm Trunnions are designed for enhance 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 XD319 Rocker Arm Trunnion Set is CNC machined from premium tool steel. They are then core hardened, precision ground, and nitrided. These extra steps in manufacturing provide increased durability and an extended life giving you a part that's stronger and more reliable than the factory part it is replacing. Sold as a set of 12. Each set includes a refinishing kit so you can polish the galled rocker arm surfaces before installing the XD319 Rocker Arm Trunnion Set in your truck.
