• PREMIUM LS ROCKER ARM TRUNNION UPGRADE KIT DO NOT SKIP THIS ON YOUR LS BUILD The factory LS rocker arm trunnion is a known failure point across the entire LS engine family.

This retrofit trunnion kit converts stock LS rocker arms into captured roller bearing rocker arms eliminating the factory failure point entirely. Trusted in everything from stock 4.8L daily drivers to 1,000+ horsepower turbo motors.

Each BTR V3 cam is born from its own specific cam core no generic cores used resulting in more average torque, higher peak power, and maximum depth heat treatment for long-term reliability.
