COMP Cams Rockers CB 1.8 7/16in Ultra Pro

If you're working on a Big Block Chevy engine, these COMP Cams Ultra Pro Magnum XD rocker arms are a solid option for your valve train. This set includes 8 rocker arms, each featuring a 1.8 ratio and designed for a 7/16 inch stud. They are built from 8650 steel, which is known for its durability and ability to outperform many import rockers. The unique machined billet pushrod seat insert adds another layer of toughness where it counts.

These rocker arms are designed for endurance and performance, utilizing advanced computer modeling to optimize strength and stiffness. They come with precision-sorted needle bearings and hardened roller tips. This setup helps distribute load more effectively and reduces wear, leading to a longer service life for your engine components. They are also fully rebuildable, meaning you can service them down the line if needed. Plus, they generally work with most common spring and retainer diameters, making installation smoother.

This set is a good choice for a range of classic Chevrolet applications, including models like the Chevelle, Camaro, and Impala from the 1960s and 70s. They are designed to fit right and help your engine perform reliably.
