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 tenancy to fail. These rocker arms are a must have for any aggressive heads and cam combo. We utilize LS3 rocker arms and new LS rocker arm retro-fit trunnion kit that replaces the cageless, loose OEM needle bearings and powdered metal trunnion with a premium 8620 steel alloy trunion and caged roller bearings for added durability. The new design from utilizes caged roller bearings that greatly reduce the possibility of the bearing failure experienced with stock LS needle bearings, which can send loose needles throughout the engine upon failure.
Michigan Motorsports' billet LS rocker stands are an excellent upgrade for your valvetrain. CNC Machined in the USA from 6061 Billet Aluminum, these stands offer improved rigidity and reduced flex compared to the OEM stands, as well as more consistent rocker saddle heights. The OEM GM stands can vary as much as .015", making it difficult to set consistent lifter preload heights especially when dealing with short travel aftermarket lifters. The rocker heights on these billet stands are true within .001" over their full length. Replaces GM # 12600936.
