BTR V2 Rocker Arm Trunnion Upgrade Kit GM LS
BTR V2 Trunnion Kit
The Brian Tooley Racing (BTR) V2 Trunnion Kit is the culmination of continuous development and real-world testing, building on the proven performance of the original V1 design. Engineered for exceptional strength and reliability, the V2 kit features trunnions with pre-installed inner race bearings and pressed inner races manufactured from premium 52100 heat-treated bearing steel — a significant upgrade from the 8620 carburized steel used in the V1 and many OEM applications.
This advanced design enhances durability under extreme conditions and incorporates a self-oiling axle that prioritizes lubrication to the trunnion itself, ensuring optimal performance and long-term reliability. The BTR V2 Trunnion Kit exemplifies BTR’s commitment to innovation, precision engineering, and race-proven valvetrain performance.
