CHE Precision LS & LT Rocker Trunnion Kit - CHE4290. Sold as described below; installation labor and tuning are not included.
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.
