COMP Cams Rocker Armes Tw 1.52 3/8 Ultra

Starting with investment cast 8650 chromemoly steel, these Ultra Pro Magnum roller rocker arms are built for strength and rigidity. The arched, web-like design helps reduce rotational inertia while optimizing balance, and the black oxide exterior finish adds a layer of corrosion resistance for improved durability. These are specifically designed for the intake valves on Small Block Chevy engines equipped with Twisted Wedge heads, using a 3/8" stud and offering a 1.52 ratio. They are intended for use with up to 850 lbs of open spring pressure.

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 fitment issues. These fit a wide range of vehicles, including popular models like the Chevrolet Camaro, Corvette, and C10, as well as Buick Regal and Cadillac Eldorado.
