Comp Cams Trunnion Upgrade Kit GM LS7/GEN-V LT1 Rocker Arm 13704TL-KIT

Factory rocker arm bearings wear under sustained high-RPM operation, leading to increased friction, valve train instability, and potential catastrophic failure. This Comp Cams trunnion upgrade kit replaces worn needle bearings with precision components, restoring proper bearing preload and eliminating rocker arm slop. If you're running your LS7 or Gen-V LT1 hard—whether on track or in competition—this kit is essential maintenance that directly impacts reliability and valvetrain geometry.

The kit includes everything needed for a complete trunnion bearing renewal, with a dedicated installation tool that simplifies what would otherwise be a tedious teardown. You'll regain the tight tolerances your engine demands, reduce parasitic losses, and extend the service life of your entire valvetrain assembly.
