Product Details

When you're rebuilding the top end of your Ford engine, you want parts that are built to last. This set of COMP Cams Ultra Pro Magnum XD rocker arms is machined from tough 8650 steel, a material known for its durability. They feature a unique machined billet pushrod seat insert, which adds another layer of strength right where it's needed most. These stud-mount rockers are designed to handle up to 1,000 lbs of spring pressure, making them a solid choice for many performance applications.

The 1.73 ratio on these rockers helps to increase valve lift, and they're set up for a 7/16" stud size. COMP Cams designed these with precision-sorted needle bearings and hardened roller tips. This setup helps to distribute the load more evenly and reduces wear on the valve train components, leading to a longer service life for your engine. They're also designed to work with most common spring and retainer diameters, simplifying installation.

This particular set is intended for use with Ford Boss 302, 351 Cleveland, and 429-460 engines. They fit a wide range of Ford and Lincoln vehicles from the late 60s through the early 90s, including models like the Ford Mustang, Torino, and Lincoln Continental. These rockers are also fully rebuildable, so you can maintain them for continued performance.
