COMP Cams Rocker Arms CS Tw 1.6 7/16 Ultra

Starting with the 8650 chromemoly steel body and an arched, web-like design, these COMP Cams Ultra Pro Magnum rocker arms are built for strength and rigidity. This construction helps reduce moment of inertia, optimizing the dynamic balance of your engine's valvetrain. They are specifically designed for SBC intake valves when using Twisted Wedge heads and a 7/16" stud, featuring a 1.6 ratio for improved lift.

The unique black oxide exterior finish not only looks good but also helps prevent corrosion and increases durability. Inside, you'll find oversized trunnions, precision-sorted needle bearings, and hardened roller tips, all contributing to dependable performance. COMP Cams has also optimized the retainer and valve spring clearances, allowing these rockers to work with most common spring diameters, retainers, and +.050" locks without clearance issues. They are rated for use with up to 850 lbs of open spring pressure.

These rocker arms fit a wide range of vehicles, including many Chevrolet, Buick, and Cadillac models from the 1980s and 1990s. They are a solid option for anyone rebuilding or upgrading their Small Block Chevy engine with Twisted Wedge heads.
