COMP Cams Rocker Arms CS 1.52 7/16 Ultra

These COMP Cams Ultra Pro Magnum Roller Rocker Arms are a well-built upgrade for a wide range of Chevrolet V6 engines, including popular models like the Chevrolet Astro, Blazer, and S10 trucks. They feature a 1.52 ratio and a 7/16" stud diameter, designed to improve valve lift and duration compared to stock components.

Constructed from investment cast 8650 chromemoly steel with an arched, web-like design, these rocker arms offer increased strength and rigidity while reducing rotational mass. This helps optimize the engine's dynamic balance. The black oxide exterior finish adds a layer of corrosion resistance for improved durability. Inside, they feature oversized trunnions, precision-sorted needle bearings, and hardened roller tips for smooth operation and long-term dependability, even with up to 850 lbs of open spring pressure. The design also accounts for retainer and valve spring clearances, making them compatible with most common spring diameters and +.050" locks without fitment issues.

This set is designed for direct installation on many V6 applications, but it's always a good idea to double-check your specific engine's requirements to ensure compatibility.
