You don’t have to worry about nasty needle bearings escaping into your engine anymore! We have a high performance, high RPM solution! CHE Precision offers LS/LT, Ford 7.3L Godzilla, and Viper Trunnion Kit upgrades designed to improve the life and performance of your engine.
Our trunnion kits are compatible with stock rocker bolts and the easy assembly kits only require snap ring pliers and lube. The kits include hardened-steel trunnions, bronze bushings, and retainer clips.
By replacing the stock caged roller bearing assembly with CHE’s uniquely designed kits, the low-mass rotating weight is maintained, while providing superior reliability for high RPM race engines. With 35+ years of industry experience, CHE has developed its own proprietary material that has revolutionized the industry by setting a new standard for wear and performance.
The trunnion bushings are made of this proprietary bronze material, with superior oil-grooving technology, and provide substantially more load-bearing strength along with maximum lubrication.
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.
