COMP Cams Rocker Arms CS 1.6 7/16 Ultra

If you're working on a Chevrolet Small Block V8 engine, these COMP Cams Ultra Pro Magnum roller rocker arms are a solid choice for improving your valvetrain's performance and durability. Designed for engines from 265 to 400 cubic inches and using a 7/16" stud diameter, they offer an improved 1.6 ratio to help your engine breathe better. These are built for engines like those found in classic Camaros, Corvettes, and C10 trucks, among many other applications.

What sets these apart is the investment cast 8650 chromemoly body, which is shaped with an arched, web-like design. This construction not only makes them strong and rigid but also helps reduce rotational weight, optimizing how the valvetrain behaves at higher RPMs. They feature oversized trunnions, precision-sorted needle bearings, and hardened roller tips for smooth operation and long life. The black oxide exterior finish is there to help prevent corrosion and add to their overall durability. Plus, the retainer and valve spring clearances are optimized, meaning you can use most common spring diameters, retainers, and +.050" locks without running into fitment issues.

These rocker arms are built to handle up to 850 lbs of open spring pressure, making them suitable for many performance builds. COMP Cams backs these with a lifetime warranty against breakage, which speaks to their well-built nature. When installing, always refer to the manufacturer's instructions for proper setup and any specific hardware requirements.
