COMP Cams GM LS1 Upgraded OEM Rocker Arms - Set of 16

With upgraded trunnions that are secured by snap rings along with a black oxide finish, our upgraded OE LS rockers offer higher lift capacity than stock. Featuring a 1.7 ratio, these 1477 rockers fit LS1, LS2 and LS6 engines. 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.
