Comp Cams GM LS3 Upgraded OEM Rocker Arms

If you're pushing your GM LS3 engine beyond stock power levels, you'll want to pay close attention to the valve train. Stock rocker arms can sometimes suffer from needle bearing failure when the engine's load increases. COMP Cams has developed an upgraded rocker arm set designed to address this common issue, offering a more robust solution for your performance build.

These aren't just stock rockers with a new coat of paint. COMP Cams engineers have re-engineered the trunnion and bearing design to incorporate a captured roller bearing system. This means the bearings are held securely in place, preventing the kind of failure that can happen with cageless designs under increased stress. The trunnions themselves are secured with snap rings for added security. With a 1.7 ratio, these rockers can increase your engine's lift capacity, helping you achieve better airflow and more power. They feature a durable black-oxide finish and are built to fit LS1, LS3, and LS7 valve train geometries, making them a solid option for a wide range of GM LS-based engines found in vehicles like the Chevrolet Camaro, Cadillac CTS, and GMC Sierra.

This set is designed as a direct replacement for your stock rocker arms, simplifying installation. For those looking to upgrade from completely stock components, COMP Cams also offers a DIY kit that includes helpful tools for installation. Investing in these upgraded rockers is a smart move to ensure the longevity and reliability of your engine's valve train, especially when you're aiming for higher performance.
