CHE High Performance LS & LT Rocker Trunnion Kit

CHE Precision has helped develop with our own Raceshop engine builder Kurt Urban one of the most advanced high performance trunnion replacement kits on the market today for LS1, LS2, LS3, LS6, LS7, LS9, the GEN5 LT1 and LT4 stock rockers.

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 CHE’s precision machined trunnion and proprietary bushing material, this unique design maintains 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, CHE and the SDPC Raceshop have the solution.
