COMP Cams Rockers CB 1.75 7/16in Ultra Pro

COMP Cams Ultra Pro Magnum XD Roller Rocker Set with 1.75 ratio for BBC (Big Block Chevrolet). Built for accuracy and strength in demanding applications, these rocker arms are constructed from durable 8650 steel for enhanced accuracy and strength in high-stress environments. They include a machined billet pushrod seat insert for precise ratio control and are equipped with precision-sorted needle bearings to effectively distribute load and reduce wear.

Designed using advanced FEA and CAD analysis to optimize strength, stiffness, and moment of inertia, making them suitable for endurance, circle track, and drag racing applications. They work with most common spring and retainer setups. This set includes 16 rocker arms and features a 7/16 inch stud size, common on many performance big-block Chevy engines. Also fits various Ford applications.
