What is the benefit of the roller tip on these rocker arms?

The hardened roller tips on these rocker arms reduce friction against the valve stem. This leads to smoother operation, less wear on both the rocker and the valve stem, and can contribute to improved valvetrain stability.

What is the maximum spring pressure these rocker arms can handle?

COMP Cams guarantees the rocker bodies against breakage for life, provided you do not exceed 850 lbs of open spring pressure. Exceeding this pressure may compromise the rocker arm's integrity.

Do these rocker arms come as a set for all cylinders?

Yes, these are sold as a set of 8 rocker arms, which is suitable for a V8 engine. This set covers all the intake and exhaust valves for one cylinder bank.

Product Details

COMP Cams is well-known for making performance engine parts, and their Ultra Pro Magnum Roller Rocker Arms are a solid option for anyone looking to improve their engine's valvetrain. These are stud-mount rockers designed for a range of Chevrolet Small Block V8 engines, from 265 to 400 cubic inches. If you're rebuilding the top end of your engine or just looking for a more stable and durable rocker arm, these are worth considering.

Built from 8650 chromemoly, these rocker arms feature an arched, web-like design that adds strength and rigidity without adding a lot of weight. This construction helps reduce the moment of inertia, which is important for keeping the valvetrain balanced at higher RPMs. They also come with oversized trunnions, precision-sorted needle bearings, and hardened roller tips for smooth operation and long life. The black oxide finish helps prevent corrosion, and COMP Cams backs them with a lifetime warranty against breakage, as long as you don't exceed 850 lbs of open spring pressure.

One of the practical benefits of these rockers is the optimized retainer and valve spring clearances. This means you can generally use a variety of spring diameters, retainers, and +.050" locks without running into clearance issues during installation. They fit a wide range of vehicles, including many Chevrolet C10 trucks, Camaros, and Caprices from the 1980s and early 90s.
