Rocker Arms and Trunnion Kits
Rocker Arms & Trunnions
Michigan Motorsports offers a complete lineup of LS and LT rocker arms and trunnion upgrade kits engineered for superior strength, stability, and longevity. Our precision-machined trunnion kits replace the weak factory needle bearings with heavy-duty, captured bearings for improved reliability in high-RPM and high-spring-pressure applications. Whether you’re rebuilding a stock valvetrain, upgrading for a performance camshaft, or preparing for race duty, our rocker arms and trunnions deliver the durability and valve train control your LS or LT engine needs to perform at its best.
