CHE Precision’s Shaft Mount Trunnion Kit is a high-quality, precision-engineered kit designed to ensure utmost rigidity and optimal performance of your valvetrain. The shaft kit system minimizes rocker arm movement, which reduces valve train deflection and provides more consistent valve actuation and improved stability. Unlike traditional shaft mount trunnion designs, CHE Precision’s shaft kit system keeps the valvetrain harmonics isolated to only one cylinder.

Manufactured using advanced materials and cutting-edge technology, this kit is built to withstand significantly high load applications. This kit features a full floating bushing, designed to reduce wear and increase longevity compared to non-floating designs. The shaft system minimizes rocker arm movement, which reduces valve train deflection and provides more consistent valve actuation and improved stability. Ideal for supercharged, ultimate street, marine, and all other high power applications, this kit enhances overall operational efficiency and contributes to the smooth functioning of your valvetrain.

For use with standard valve location heads only. Will not work with some aftermarket cylinder heads that have revised valve angles or locations. 

Rocker Arm Bodies Not Included
