COMP Cams Rocker CB 1.8 7/16in Ultra Pro

If you're working on a Chevrolet Big Block engine, these COMP Cams Ultra Pro Magnum XD rocker arms are a solid choice for improving valve train performance. They feature a 1.8 ratio and are designed to work with 7/16" studs, commonly found on engines like the 396, 427, and 454. These rockers are built to handle demanding applications, including endurance and drag racing, thanks to their robust construction.

What sets these apart is the durable 8650 steel construction, paired with a unique machined billet pushrod seat insert. This combination offers exceptional durability and can withstand up to 1,000 lbs of spring pressure. They also utilize precision-sorted needle bearings and hardened roller tips. This design helps distribute load more effectively, reducing wear and extending the service life of your valve train components. Plus, they are designed to work with most common spring and retainer diameters, making installation more straightforward.
