They are constructed from durable 8650 steel, a material chosen for its strength and ability to withstand the rigors of high-performance engines. This robust construction allows them to handle spring pressures up to 1,000 lbs, making them a solid choice for builds that demand reliability under extreme conditions.

The 1.6 ratio on these stud-mount rockers is designed to work with 7/16-inch studs, commonly found on Ford 289, 302, and 351 Windsor engines, as well as a wide range of other V8 applications from American Motors and Ford. Precision-sorted needle bearings and hardened roller tips are used to ensure smooth operation and reduce wear, distributing loads effectively for a longer service life. These rockers are also fully rebuildable, offering a long-term value for your engine build. Their design has been optimized using advanced FEA and CAD analysis to improve strength and stiffness, making them well-suited for demanding applications like drag racing or circle track.

When you're looking for rocker arms that can handle significant spring pressure and offer improved durability, these Ultra Pro Magnum XD units are a well-built option. They are designed to work with most common spring and retainer diameters, simplifying installation into your existing cylinder heads. If you're rebuilding a performance V8 and need components that can stand up to the stress, these COMP Cams rockers are a dependable choice.
