COMP Cams Rocker Arms CS 1.6 7/16 Ultra

This set includes COMP Cams Ultra Pro Magnum roller rocker arms, designed to improve valve train stability and performance. They feature a 1.6 ratio and a 7/16" stud diameter, suitable for a wide range of V6 Chevrolet engines, including popular models like the Chevrolet Astro, Blazer, and Express vans. These are a well-built upgrade for those looking to enhance their engine's valvetrain.

Constructed from investment cast 8650 chromemoly steel, these rocker arms are built to last. The arched, web-like design adds strength and rigidity while also reducing rotational inertia for better dynamic balance. A unique black oxide exterior finish not only looks good but also helps prevent corrosion and increases overall durability. Inside, you'll find oversized trunnions, precision-sorted needle bearings, and hardened roller tips, all contributing to improved performance and dependability. The design also offers optimized retainer and valve spring clearances, allowing for compatibility with most common spring diameters and +.050" locks without fitment issues. These are rated for use with up to 850 lbs of open spring pressure.

COMP Cams backs these rocker bodies with a lifetime warranty against breakage, reflecting their confidence in the product's strength and longevity. If you're rebuilding the top end of your V6 Chevrolet or looking for a more robust valvetrain component, these well-made rocker arms are a solid option.
