COMP Cams Rocker Arms CS 1.52 3/8 Ultra

This set includes COMP Cams Ultra Pro Magnum roller rocker arms, designed to improve valve train performance. They feature a 1.52 ratio and a 3/8" stud diameter, suitable for a wide range of Chevrolet V6 engines, including models like the Chevrolet Astro, Blazer, and Camaro. These rockers are built to handle demanding conditions and offer improved stability over stock components.

Constructed from investment cast 8650 chromemoly steel, these rocker arms have an arched, web-like design that increases strength and rigidity while reducing rotational mass. The black oxide exterior finish helps prevent corrosion and adds durability. Inside, they feature oversized trunnions, precision-sorted needle bearings, and hardened roller tips for smooth operation and long life. The design also accounts for optimized retainer and valve spring clearances, allowing compatibility with most common spring diameters and locks.

These rockers are rated for use with up to 850 lbs of open spring pressure, making them a solid option for performance builds. COMP Cams backs these rocker bodies with a lifetime warranty against breakage.
