COMP Cams Rocker Arms CS 1.6 3/8 Ultra

If you're working on a Chevrolet Small Block V8 engine, these COMP Cams Ultra Pro Magnum Roller Rocker Arms are a solid choice for improving your valvetrain's performance and durability. Designed for engines ranging from 265 to 400 cubic inches, they feature a 1.6 ratio and a 3/8-inch stud diameter, making them a direct fit for many popular Chevy applications like the Camaro, Corvette, and C10 trucks from the 80s and early 90s.

These rocker arms are built from investment cast 8650 chromemoly steel, which gives them increased strength and rigidity. COMP Cams uses an arched, web-like design that helps reduce rotational mass, optimizing the balance of your valvetrain. The unique black oxide exterior finish not only looks good but also helps prevent corrosion and adds to the overall durability. Inside, you'll find oversized trunnions, precision-sorted needle bearings, and hardened roller tips, all contributing to smoother operation and reduced friction under high spring pressures, up to 850 lbs. The design also accounts for valve spring and retainer clearances, allowing for compatibility with most common setups without issues.

This set includes everything you need to upgrade your rocker arms, and COMP Cams backs them with a lifetime warranty against breakage. This means you can install them with confidence, knowing they're built to last through demanding use.
