Michigan Motorsports Rocker Arm Trunion Kit - Specific to Gen V LT1 LT4 LV3 L83 L86
These LS Series retrofit trunion kits are designed to convert stock LS Series rocker arms into captured roller bearing rocker arms. The factory bearings are a known failure on the LS Engines. When they fail they send small bearings through the entire engine. The upgraded trunions use a captured roller bearing allowing for a reliable smooth rotation. The upgraded trunions also give more stability at higher RPM.
We use these trunion kits in anything from stock 4.8's all they way up to 1,000+hp turbo motors.
16 rocker arm trunions
32 rocker arm retaining rings
16 upgraded bolts
2 washers for pressing bearings
Installation is fairly simple with the use of a press or a simple vise along with basic hand tools. Instructions are included to aid in the installation.
