Product Details

If you're working on the top end of your 1970-1976 Chevrolet Caprice, especially a Big Block engine, these COMP Cams Ultra Pro Magnum XD rocker arms are a solid choice. This set includes 12 rockers, each featuring a 1.6 ratio and designed for a 7/16 inch stud. They're built to handle the demands of performance engines, offering an improved way to manage valve lift and duration.

What sets these apart is the durable 8650 steel construction, which is known for outlasting many other rocker arms. You'll find a unique machined billet pushrod seat insert that adds exceptional durability right where it's needed most. COMP Cams also incorporated precision-sorted needle bearings and hardened roller tips. These features work together to better distribute the load across the valve train and reduce wear, leading to a longer service life for your engine components. They're also designed to work with most common spring and retainer diameters, making installation more straightforward. The XD design itself has been developed using advanced engineering tools to optimize strength and stiffness.

This set is fully rebuildable, meaning you can service them down the road if needed. They are a well-built option for anyone looking to get the most out of their Chevrolet Big Block engine, whether it's for endurance, drag racing, or circle track applications.
