Michigan Motorsports LS Rocker Arms and Trunnion Kits
Whether you have a stock LS motor or a highly modified LS motor, replacing your rockers with a true roller bearing setup is highly recommended. The stock bearings have a tendency to fail. These rocker arms are a must have for any aggressive heads and cam combo and are the same rockers we utilize on our 1,000 hp Turbo Motor. We take LS Series rocker arms and install our trunnion kit that replaces the cageless, loose OEM needle bearings and powdered metal trunnion with a premium 8620 steel alloy trunnion and caged roller bearings for added durability.
