Product Details

COMP Cams is well-known for performance engine components, and their Ultra Pro Magnum Roller Rocker Arms take stud mount rocker performance to a new level. These are designed for Chevy V8 engines with 396-454 cubic inch displacements and use a 7/16" stud with a 1.7 ratio. They offer improved stability and value for your build.

The rocker arms are made from 8650 chromemoly material with an arched, web-like design. This construction increases strength and rigidity while also reducing the moment of inertia for better dynamic balance. A black oxide exterior finish helps prevent corrosion and adds durability. Inside, you'll find oversized trunnions, precision-sorted needle bearings, and hardened roller tips for dependable performance. The design also accounts for optimized retainer and valve spring clearances, allowing compatibility with most common spring diameters and +.050" locks without issues.

These rocker arms are built to handle up to 850 lbs of open spring pressure and come with a lifetime warranty against breakage of the rocker bodies. They fit a wide range of Chevrolet vehicles, including models like the Impala, Chevelle, and Corvette from the 1960s and 70s.
