COMP Cams Rocker CS 1.6 7/16in Ultra Pro

Machined from tough 8650 steel, these COMP Cams Ultra Pro Magnum XD rocker arms feature a unique billet pushrod seat insert that adds a notable layer of durability. They are built to handle significant spring pressure, up to 1,000 lbs, making them a solid choice for performance builds. The 1.6 ratio is designed for use with 7/16" studs on a variety of Chevrolet V6 and Small Block engines, including popular applications like the 265-400 cubic inch small blocks.

These rockers are also designed with precision-sorted needle bearings and hardened roller tips. This setup helps to better distribute the load across the valve train components, reducing wear and extending the service life of your engine. They are fully rebuildable and generally work with most common spring and retainer diameters, simplifying installation and maintenance. The XD design itself uses advanced engineering analysis to optimize strength and stiffness for demanding use.
