The COMP Cams GM LS OEM Rocker Arm Upgrade Kit and Installation Tool is designed to be a simple, do-it-yourself upgrade to the LS valve train. The kit utilizes captured Roller bearings and billet trunnions that perform well in high-RPM Race Applications and prevent engine damage from Roller bearing failure. The included magnetic Installation tool allows for one-handed Installation, and its cylindrical construction is perfect for use in an arbor press, vice or c-clamp. The kit provides both increased lift capability over fully stock Rockers and improved valve train durability. It is ideal for a quick budget performance upgrade.
