V2 Rocker Arm Trunnion Upgrade Kit

The V2 Rocker Arm Trunnion Upgrade Kit from Brian Tooley Racing is designed for performance builders and mechanics focused on enhancing valve train durability and reliability in high-rpm applications. This kit is particularly beneficial for those working on LS-platform engines, where valve train stress is elevated due to modified cam profiles, forced induction, or race builds.

Rocker arm trunnions serve as critical pivot points that support lateral loads during valve actuation. The V2 design improves upon previous iterations with enhanced geometry and material specifications, allowing for better handling of sustained high-load conditions without deflection or wear. This upgrade kit replaces stock trunnions with precision-manufactured components that maintain tighter tolerances and more consistent bore dimensions than OEM parts.

Installation is straightforward for experienced engine builders, as the kit integrates directly into existing rocker arm platforms without requiring additional machine work or modifications to cylinder heads. This upgrade is essential for those looking to maximize performance and longevity in their LS-platform engines, ensuring stable valve timing geometry across the full rev range.
