COMP Cams Rocker Arm FS/FW 1.6 3/8 Ultra

If you're working on the valvetrain of your Ford 289, 302, or 351W engine, or similar V8s from Buick and Chevrolet, these COMP Cams Ultra Pro Magnum rocker arms are a solid option. They're designed to handle up to 850 lbs of open spring pressure, giving you the stability you need for improved performance. The 1.6 ratio helps to increase valve lift, which can make a noticeable difference in how your engine breathes.

These rockers are made from investment cast 8650 chromemoly steel with a unique arched, web-like design. This construction not only makes them strong and rigid but also helps reduce the moment of inertia for better dynamic balance. They feature oversized trunnions, precision-sorted needle bearings, and hardened roller tips for dependable operation. The black oxide exterior finish helps prevent corrosion and adds to their durability. Plus, they're designed with optimized retainer and valve spring clearances, so you can use most common spring diameters and locks without issues.

This set is built to fit engines using a 3/8" diameter stud. They come with a lifetime warranty against breakage, reflecting COMP Cams' confidence in their strength.
