Product Details

When you're rebuilding the top end of your Ford engine, you want components that are built to last and perform. This set of COMP Cams Ultra Pro Magnum XD rocker arms gives you a 1.7 ratio, designed to work with 7/16" studs on Ford 289, 302, and 351 Windsor engines. These rockers are a solid choice for a wide range of Ford vehicles, including models like the Mustang, Fairlane, and F-Series trucks from various years.

What sets these rockers apart is their construction. They're machined from durable 8650 steel, a material known for its strength and longevity, and they feature a unique machined billet pushrod seat insert for added toughness. COMP Cams has also incorporated precision-sorted needle bearings and hardened roller tips. This design helps distribute load more effectively and reduces wear, which means a longer service life for your engine. They're also designed to handle up to 1,000 lbs of spring pressure and work with most common spring and retainer diameters, making them versatile for many builds. The XD design itself has been refined using advanced engineering tools to optimize strength and stiffness for demanding applications.

These Ultra Pro Magnum XD rocker arms are fully rebuildable, giving you the option to service them down the line. If you're looking for a well-built rocker arm set that can stand up to the demands of your Ford V8, this COMP Cams option is worth considering.
