COMP Cams Rocker Arm CS Tw 1.52 7/16 Ultra

Starting with the investment cast 8650 chromemoly steel body, these COMP Cams 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. This particular rocker arm is designed for the intake valves on Small Block Chevy engines equipped with Twisted Wedge heads, using a 7/16" stud and featuring a 1.52 ratio.

The black oxide exterior finish not only looks sharp but also helps prevent corrosion and increases durability. Inside, you'll find oversized trunnions, precision-sorted needle bearings, and hardened roller tips for reliable performance. COMP Cams engineered these with optimized retainer and valve spring clearances, meaning they work with most common spring diameters, retainers, and +.050" locks without issues. They're rated for use with up to 850 lbs of open spring pressure, making them a solid choice for many performance builds.

These rocker arms fit a wide range of vehicles from the 1980s and 1990s, including popular models like the Chevrolet Camaro, Chevrolet Corvette, and Buick Regal. Remember that Twisted Wedge heads use standard SBC exhaust valve rockers, so these are specifically for the intake side.
