COMP Cams Rocker Arms CS 1.52 3/8 Ultra P

Built from investment cast 8650 chromemoly steel, these Ultra Pro Magnum rocker arms feature an arched, web-like design that increases rigidity while reducing rotational mass. This construction, combined with a unique black oxide exterior finish, helps prevent corrosion and adds to their durability. They are designed to handle up to 850 lbs of open spring pressure, making them a solid option for many V6 engines, including those found in Chevrolet Astro vans and S10 pickups from 1988 and later, as well as Buick and Cadillac models from the early to mid-2000s.

These rockers include oversized trunnions, precision-sorted needle bearings, and hardened roller tips for reliable performance. The design also offers optimized retainer and valve spring clearances, allowing for compatibility with most common spring diameters, retainers, and +.050" locks without interference issues. COMP Cams backs these rocker bodies with a lifetime warranty against breakage, demonstrating their confidence in the strength and dependability of this component.
