COMP Cams Rocker Arms CS 1.52 7/16 Ultra

If you're rebuilding the top end of your Chevrolet Small Block V8, especially one from the 265-400 cubic inch range, you're likely looking for rocker arms that can handle increased spring pressures and maintain stability. These COMP Cams Ultra Pro Magnum roller rocker arms are built for that exact scenario. They feature a 1.52 ratio and are designed to work with a 7/16" diameter stud, making them a solid choice for many popular Chevy V8 applications.

What sets these apart is the investment cast 8650 chromemoly steel body, which is formed with an arched, web-like design. This construction not only makes them strong and rigid, capable of handling up to 850 lbs of open spring pressure, but it also helps reduce rotational mass for better dynamic balance. The unique black oxide exterior finish is there to help prevent corrosion and add to their durability. Inside, you'll find oversized trunnions, precision-sorted needle bearings, and hardened roller tips, all contributing to improved performance and long-term dependability. COMP Cams also optimized the retainer and valve spring clearances, so you can use most common spring diameters, retainers, and locks without running into fitment issues.

These rocker arms are designed to fit a wide range of Chevrolet V8 engines found in vehicles like the Chevrolet Camaro, Corvette, and C10 trucks, as well as many Buick and Cadillac models from the late 70s through the mid-90s. They come with a lifetime warranty against breakage, which speaks to their well-built nature.
