Product Details

When you're rebuilding the top end of your engine, you need components that can handle the stress and keep performing. This set of COMP Cams Ultra Pro Magnum XD rocker arms gives you a full set of eight, featuring a 1.6 ratio and designed for a 3/8-inch stud. These are built from tough 8650 steel, a material known for its ability to outlast and outperform many other rockers on the market. They also include a unique machined billet pushrod seat insert for added durability where it counts.

What sets these apart is the attention to detail in their construction. They use precision-sorted needle bearings and hardened roller tips, which help to distribute the load more evenly and reduce wear, leading to a longer service life for your valvetrain. These rockers are also designed to be fully rebuildable, meaning you can service them down the road if needed. They're made to work with most common spring and retainer diameters, making them a versatile choice for many Chevrolet and GM-based engines, including popular models like the Chevrolet Camaro, Corvette, and Chevelle, as well as many Buick and Cadillac applications.
