CHE LS Trunnion Upgrade

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 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.
