Product Description
OEM LS1 Rocker Arms with CHE Bronze Bushing Trunnion Kit Installed 4.8 5.3 5.7 6.0 LS
Whether you're running a stock LS engine or a performance heads-and-cam combination, upgrading the factory rocker trunnions is highly recommended. These OEM LS rocker arms come pre-assembled with the CHE Bronze Bushing Style Trunnion Upgrade, offering a significant improvement in durability and reliability over factory needle-bearing trunnions.
Factory needle bearings are known to fail under increased RPM and increased spring pressures. The CHE bronze bushing design provides superior load handling and lubrication, helping protect your engine from catastrophic valvetrain failure while supporting aggressive performance applications.
