Stock LS Rocker arms can experience cageless needle bearing failure when loads are increased. COMP Cams engineers have solved this problem with upgraded Rockers featuring a stronger and more durable trunnion and captured bearing design. These upgraded Rockers increase lift capacity and utilize caged precision Roller bearings to improve valve train durability. The trunnions are secured by snap rings. The Rockers feature a black-oxide finish and are available for LS1, LS3 and LS7 valve train geometries. A DIY upgrade kit is also available for users with stock Rockers. It features a magnetic Installation tool, and its cylindrical construction is perfect for use in an arbor press, bench vise or c-clamp.
