COMP Cams Rocker Arm CS Tw 1.52 3/8 Ultra

Starting with investment cast 8650 chromemoly steel, these Ultra Pro Magnum rocker arms are built for strength and rigidity. The arched, web-like design helps reduce the moment of inertia, optimizing the dynamic balance of your engine's valvetrain. A black oxide exterior finish is applied to help prevent corrosion and increase overall durability. These are designed for SBC intake valves with Twisted Wedge heads and use a 3/8" stud, featuring a 1.52 ratio.

You'll find oversized trunnions, precision-sorted needle bearings, and hardened roller tips inside, all contributing to dependable performance. The design also accounts for optimized retainer and valve spring clearances, meaning you can generally use most common spring diameters, retainers, and +.050" locks without running into clearance or fitment issues. These rocker arms are well-built to handle up to 850 lbs of open spring pressure and come with a lifetime warranty against breakage of the rocker bodies.

This rocker arm is a solid option for a wide range of vehicles from the 1980s and 1990s, including popular models like the Chevrolet Camaro, Chevrolet Corvette, and Buick Regal. Always refer to the manufacturer's installation instructions for specific details regarding your application.
