Product Description
Michigan Motorsports LS1 Rocker Arms with Trunnion Bearings Professionally Installed
No bolts are included with this kit. Reuse your stock bolts or purchase bolts separately.
Upgrade your LS valvetrain with pre-assembled LS1 rocker arms featuring a true roller bearing trunnion upgrade. Whether your engine is stock or a high-output heads-and-cam build, these rockers replace the failure-prone factory needle bearings with caged roller bearings to improve durability and protect your engine from debris-related damage.
Key Benefits
