Description, Q&A
Description. The COMP Cams GM LS OEM Rocker Arm Upgrade Kit & 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.
