COMP Cams Magnum Roller Rocker Chevy SB

You get a set of eight Magnum Roller Rocker Arms, designed for Chevrolet Small Block V8 engines with 3/8" studs and a 1.6 ratio. These are a popular choice for street performance builds, aiming to get more out of your engine's valve lift. They fit a wide range of vehicles, including classic Chevrolet Bel Airs, Camaros, and Corvettes, as well as some Pontiac Firebirds and Oldsmobile Cutlass models.

These rocker arms are built from 8620 chromemoly steel, a strong material that resists flexing, which helps ensure you get the maximum possible lift from your camshaft. The roller tip on these arms is there to reduce friction compared to a standard rocker, and the overall stiff design contributes to more effective valve lift. COMP Cams stamps their logo on the underside, so you know you're getting the genuine article. They're a solid option for performance applications where you're running less than 350 lbs. of open spring pressure.
