COMP Cams Rockers FC 1.73 7/16in Ultra Pro

If you're rebuilding the top end of your Ford engine, especially for endurance, drag, or circle track racing, you need components that can handle the stress. These COMP Cams Ultra Pro Magnum XD rocker arms are designed to do just that. They feature a 1.73 ratio, which means they'll open your valves further and hold them open longer than stock, helping your engine breathe better and make more power.

What sets these rockers apart is their robust construction. They're machined from durable 8650 steel, a material known for its strength and longevity, and they include a unique machined billet pushrod seat insert for exceptional durability. These stud-mount rockers are also fully rebuildable, meaning you can service them down the line. They use precision-sorted needle bearings and hardened roller tips to distribute load effectively and reduce wear, extending their service life. Plus, they're built to handle up to 1,000 lbs of spring pressure and work with most common spring and retainer diameters, making them a versatile choice for many performance builds. The XD design itself has undergone advanced FEA and CAD analysis to optimize strength and stiffness.

These rocker arms fit a wide range of Ford vehicles, including popular models like the Ford Mustang, Torino, and LTD. They are specifically designed for Ford Boss 302, 351 Cleveland, and 429-460 engines using a 7/16 inch stud. If you're looking for a well-built, high-performance rocker arm set that can stand up to demanding use, these Ultra Pro Magnum XD rockers are a solid option.
