Product Details

What you get in this kit are a pair of COMP Cams Ultra Pro Magnum XD rocker arms. These are stud-mount rockers designed for a 1.6 ratio and use a 7/16 inch stud. They're built from durable 8650 steel, which is known for holding up well under stress, and feature a unique machined billet pushrod seat insert for added strength. This design helps them handle spring pressures up to 1,000 lbs, making them a solid option for many performance builds.

The Ultra Pro Magnum XD rockers are also designed to be fully rebuildable, which is a nice touch for long-term service. They use precision-sorted needle bearings and hardened roller tips. This setup helps distribute the load more evenly and reduces wear on the valve train components, leading to a longer service life. They're made to work with most common spring and retainer diameters, simplifying installation in a variety of engine setups. These rockers fit a wide range of Ford and American Motors V8 engines, including popular choices like the Ford 289, 302, and 351 Windsor, as well as AMC models like the Ambassador and Matador.
