COMP Cams Rocker Arms CS1.52 3/8 Ultra P

Starting with investment cast 8650 chromemoly steel, these COMP Cams Ultra Pro Magnum rocker arms are built for serious performance. The arched, web-like design isn't just for looks; it adds significant strength and rigidity to the rocker body. This well-built construction helps reduce the moment of inertia, which means the rockers can respond faster to camshaft lobe movements, optimizing the dynamic balance of your valvetrain. This attention to detail is crucial for engines that see a lot of action.

You'll also appreciate the unique black oxide exterior finish, which offers a solid defense against corrosion and adds to the overall durability. Inside, these rockers feature oversized trunnions, precision-sorted needle bearings, and hardened roller tips. These components work together to ensure smooth operation and dependable performance, even under demanding conditions, handling up to 850 lbs of open spring pressure. The design also accounts for valve spring and retainer clearances, allowing for compatibility with most common spring diameters and +.050" locks without causing fitment issues.

These rocker arms are designed to fit a wide range of Chevrolet V8 engines, including popular models like the Chevrolet C1500, Camaro, and Caprice from the late 80s and 90s, specifically those with a 3/8" stud and self-aligning rockers. COMP Cams stands behind this product with a lifetime warranty against breakage, underscoring their confidence in the strength and longevity of these Ultra Pro Magnum rockers.
