Product Details

COMP Cams is well-known for making performance valvetrain components, and their Ultra Pro Magnum XD Rocker Arms are a solid choice for anyone looking to improve their engine's performance. These stud-mount rockers are built from tough 8650 steel, which is known to last longer than many other materials. They also feature a unique machined billet pushrod seat insert for extra durability where it counts.

What makes these rockers stand out is their attention to detail. They use precision-sorted needle bearings and hardened roller tips to help spread the load evenly and cut down on wear, meaning they'll keep working well for a long time. The XD design itself was developed using advanced computer analysis to optimize strength and stiffness, making them suitable for a wide range of vehicles, including many Chevrolet V6 and Small Block engines from the 1950s through the 1990s, like the Chevrolet Camaro, Corvette, and Chevelle. They can also handle up to 1,000 lbs of spring pressure, so they're ready for more aggressive setups.
