Michigan Motorsports Rocker Arm Trunion Kit is specifically designed for Gen V LT1, LT4, LV3, L83, and L86 engines. These retrofit trunion kits for the LS Series convert standard rocker arms into roller bearing rocker arms, addressing the well-known issue of factory bearing failures in LS Engines. Failure of these bearings can result in small particles circulating through the engine.

The upgraded trunions feature captured roller bearings, ensuring reliable and smooth rotation. They also enhance stability at high RPMs, making them suitable for applications ranging from stock 4.8L engines to high-performance setups exceeding 1,000 horsepower with turbochargers.

Despite their lightweight and strength, stock factory LS rocker arms benefit significantly from the installation of upgraded bearings and trunions. Post-upgrade, these rocker arms perform comparably to expensive roller rocker arms, but at a fraction of the cost. This makes the kit essential for anyone installing aftermarket cams, superchargers, turbos, or nitrous systems.

The kit contains all necessary components for installation, including rocker arm trunions, bearings, retaining rings, and upgraded bolts. The supplied bolts are slightly shorter than factory bolts to prevent protrusion into intake ports. They are stronger than standard grade 8 bolts, boasting a minimum tensile strength of 170,000 psi.
