What material are these rocker arms made from?

These COMP Cams Ultra Pro Magnum XD rocker arms are constructed from durable 8650 steel. This material is chosen for its strength and ability to withstand the stresses of engine operation, contributing to a longer service life.

Are these rocker arms a direct replacement for all Chevrolet engines?

These rocker arms are designed for a wide range of Chevrolet, Buick, and Cadillac vehicles, particularly those with 7/16 inch studs. While they fit many applications, it's important to verify fitment for your specific engine and year to ensure compatibility.

What is the benefit of the roller tip design?

The hardened roller tips on these rocker arms help to reduce friction and wear on the valve stem and tip. They also assist in better distributing the load across the valvetrain, which can lead to improved performance and a longer service life for both the rocker arms and the associated components.

Product Details

This set includes eight COMP Cams Ultra Pro Magnum XD rocker arms, featuring a 1.5 ratio and designed for a 7/16 inch stud. These are well-built components designed to handle the demands of performance engines, commonly found in a wide range of Chevrolet, Buick, and Cadillac vehicles from the 1970s through the 1990s, such as the Chevrolet Camaro, Buick Regal, and Cadillac Brougham.

Constructed from durable 8650 steel, these rocker arms are made to last and outperform many other options. They incorporate a unique machined billet pushrod seat insert for added strength and durability. The rocker arms are also fully rebuildable and utilize precision-sorted needle bearings along with hardened roller tips. This design helps to better distribute the load across the valve train and reduce wear, contributing to a longer service life for your engine components. They are designed to work with most common spring and retainer diameters.

The XD design benefits from advanced FEA and CAD development, which helps to optimize strength, stiffness, and moment of inertia. This makes them a solid option for endurance, drag racing, and circle track applications where reliability and performance are critical. If you're rebuilding or upgrading the valvetrain on your classic Chevrolet or GM vehicle, these offer a strong combination of durability and performance.
