Trunnion Upgrade Kit GM LS7/GEN-V LT1 Rocker Arm

The Trunnion Upgrade Kit GM LS7/GEN-V LT1 Rocker Arm by COMP CAMS is engineered for serious LS and LT engine builders who demand precision valve train geometry and durability under extreme conditions. This kit addresses a critical weak point in stock rocker arm assemblies: the trunnion pivot point, which supports lateral loads during high-RPM operation and aggressive valve acceleration. Whether you're building a naturally aspirated LS7 stroker or a turbocharged LT1 platform, upgrading to a reinforced trunnion assembly eliminates flex, reduces valve lash variation, and ensures consistent valve timing across the entire power band.

COMP CAMS engineered this kit with hardened steel construction and tighter tolerances than OEM rocker arms, creating a more rigid pivot support that resists deflection under peak valve spring loads. The trunnion upgrade significantly reduces rocker arm geometry errors that accumulate as boost pressure increases or valve lift exceeds factory specifications. By maintaining precise rocker arm alignment, this kit preserves valve seat contact quality and extends the service life of both the rocker arm and valve train components. Installation integrates directly with existing LS7 and Gen-V LT1 cylinder head casting designs, requiring no modification to your current valve train layout.

This upgrade is essential for anyone running elevated spring pressures, extended valve lift cams, or forced induction on LS7 and LT1 platforms. Street machines, race engines, and dedicated track builds all benefit from the improved stability and reduced wear this kit delivers. Compatibility spans both naturally aspirated and turbocharged applications, making it ideal for builders transitioning stock heads to performance specifications. Weighing 3.9 lbs and engineered to OEM mounting standards, installation fits seamlessly into your existing build timeline and requires no custom fabrication.
