COMP Cams Rocker Arms CS Tw 1.6 3/8 Ultra

What you get here are a set of COMP Cams Ultra Pro Magnum roller rocker arms, designed specifically for the intake valves on Small Block Chevy engines equipped with Twisted Wedge heads. These are the 1.6 ratio versions, using a 3/8" stud, and they're built from investment cast 8650 chromemoly steel. This material, combined with an arched, web-like design, gives them increased strength and rigidity while keeping the moment of inertia down for better performance. They also feature a black oxide exterior finish to help prevent corrosion and add durability.

You'll find these rockers are well-built with oversized trunnions, precision-sorted needle bearings, and hardened roller tips, all contributing to dependable performance. COMP Cams has also optimized the retainer and valve spring clearances so you can use most common spring diameters, retainers, and +.050" locks without running into clearance or fitment issues. They're rated for use with up to 850 lbs of open spring pressure, making them a solid option for many performance builds. These fit a wide range of Chevy V8 engines, including popular models like the Chevrolet Camaro, Corvette, and C10 Suburban.
