COMP Cams Rockers CS 1.65 7/16in Ultra Pro

In this kit, you get a set of COMP Cams Ultra Pro Magnum XD rocker arms, designed with a 1.65 ratio and a 7/16-inch stud size. These are built from tough 8650 steel, which is known to last longer than many other rocker arms out there. They also feature a unique machined billet pushrod seat insert for extra durability where it counts. This set is made to be fully rebuildable, using precision-sorted needle bearings and hardened roller tips. These components work together to help distribute load better and reduce wear, giving you a longer service life from your engine's valvetrain. They're also designed to work with most common spring and retainer diameters.

The XD design uses advanced computer modeling to improve strength and stiffness, making them a solid choice for endurance, drag, or circle track racing applications. These rockers can handle spring pressures up to 1,000 lbs, so they're well-suited for performance builds. They are specifically designed for Chevrolet 200-262 V6 engines that use a 7/16-inch stud. You'll find these fit a range of vehicles, including models like the Chevrolet Caprice, Monte Carlo, and Pontiac Grand Prix from the mid-80s to early 90s.
