COMP Cams Rocker Arm CS 1.6 3/8 Ultra Pro

When you're rebuilding the top end of your engine, you want parts that are built to last and perform. This set of Ultra Pro Magnum rocker arms from COMP Cams gives you a 1.6 ratio and uses a 3/8" diameter stud, making them a solid option for a wide range of Chevrolet V6 and Small Block Chevy engines. They're designed to handle up to 850 lbs of open spring pressure, so you know they can take a beating.

These rocker arms are constructed from investment cast 8650 chromemoly steel, featuring an arched, web-like design that increases strength and rigidity without adding a lot of extra weight. They also have a black oxide exterior finish to help prevent corrosion and increase durability over time. You'll find oversized trunnions, precision-sorted needle bearings, and hardened roller tips inside, all contributing to better performance and dependability. Plus, the retainer and valve spring clearances are optimized to work with most common spring diameters and locks, even +.050" ones, without causing fitment issues.
