Elevate your Gen V engine's performance and reliability with the Gen V/LT Rocker Arm Trunion Upgrade Kit. This comprehensive kit is specifically designed for Gen V LT1, LT4, LV3, L83, and L86 engines, replacing the factory needle bearings with captured roller bearings to enhance valvetrain stability and reduce the risk of failure under high-stress conditions.
