Rocker Arm/Trunnion Kits

The factory production LS rocker arm is a lightweight proven design, but as valve spring pressures and valve lift increased it became necessary to find ways to improve upon the stock LS rocker's reliability. By replacing the stock caged roller bearing assembly with precision machined trunnion and proprietary bushing material, this will help maintain the low-mass rotating weight of the stock LS rocker design while providing superior reliability for high RPM LS race engines. If you are looking for a professionally engineered and track tested LS trunnion rocker arm replacement, we have the solution.
