Product Details

This set includes COMP Cams Ultra Pro Magnum roller rocker arms, designed to handle demanding engine conditions. These are stud-mount rockers with a 1.7 ratio and a 7/16" stud diameter, intended for use with specific Ford V8 engines like the Boss 302, 351 Cleveland, and 429-460. They are built to withstand up to 850 lbs of open spring pressure, making them a solid choice for performance builds.

The rocker arms are constructed from investment cast 8650 chromemoly steel, featuring an arched, web-like design that increases strength and rigidity while also reducing rotational mass. This construction, combined with oversized trunnions, precision-sorted needle bearings, and hardened roller tips, contributes to improved performance and dependability. A unique black oxide exterior finish helps prevent corrosion and adds to the overall durability of the part. The design also offers optimized retainer and valve spring clearances, allowing for compatibility with most common spring diameters, retainers, and +.050" locks without clearance issues.

These rocker arms fit a wide range of Ford vehicles from the late 1960s through the mid-1990s, including models like the Ford F-150, Gran Torino, and Mustang. They come with a lifetime warranty against breakage of the rocker bodies.
