COMP Cams GM LS OEM Rocker Arm Upgrade Kit & Installation Tool

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. Our trunnion upgrade kit converts a stock LS series rocker arm into a captured trunnion for increased stability and stiffness. Compatible with stock geometry, our trunnion kit can be performed in 30 minutes with included 54702-TL tool. See 13702-KIT for kit without installation tool. See 13704-KIT for kit for GM LS7 and GEN V LT. Tool available separately under 54702-TL.
