What is the benefit of using roller rocker arms over standard ones?

Roller rocker arms, like these Magnum models, reduce friction at the valve tip due to the roller. This allows for more of the camshaft's lift to be transferred to the valve, potentially increasing horsepower and improving engine response.

What is the advantage of the 8620 chromemoly steel construction?

This material is chosen for its strength and rigidity. It resists flexing under the stress of engine operation, ensuring that the rocker arm accurately transfers the cam's intended lift to the valve, leading to more consistent performance.

Do these rocker arms come with the necessary hardware for installation?

This set includes the Magnum Roller Rocker Arms themselves. It is recommended to consult the manufacturer's installation guide for a complete list of any additional hardware or components that may be needed for proper installation on your specific vehicle.

Product Details

COMP Cams is well-known for making performance valvetrain components, and these Magnum Roller Rocker Arms are a popular choice for street performance builds. They're designed to work with Chevy Small Block V8 engines (265-400 cubic inches) and V6 engines (200-262 cubic inches) that use a 3/8" stud. If you're looking to get more out of your engine's valve lift without going to a full race setup, these are a solid option.

What makes these rockers work so well is their construction and design. They're made from 8620 chromemoly steel, which is a strong material that resists flexing. This means more of the cam's lift actually makes it to the valve. The roller tip on these arms also helps reduce friction compared to traditional stamped steel rockers, and their stiff design and accurate 1.52 ratio contribute to more effective valve lift. COMP Cams claims you can see a 15 to 30 horsepower increase over stock rocker arms, especially when used with less than 350 lbs. of open spring pressure.

You'll find the COMP Cams logo stamped on the underside of each rocker, a mark of their quality. These are a self-aligning design, which simplifies installation on many Chevy applications, including vehicles like the Chevrolet Camaro, Corvette, and GMC C1500.
