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

Roller rocker arms, like these from COMP Cams, use a needle bearing fulcrum and roller tip. This design creates significantly less friction than the sliding contact of stock rocker arms, which can help lower oil temperatures and improve engine response.

What is the spring pressure rating for these rocker arms?

These High Energy aluminum rocker arms are designed to work with engines using up to 550 lbs of open spring pressure, making them suitable for street use and moderate performance applications.

Are any other components needed for installation?

While these rocker arms are a direct replacement for the stock rocker arms, it's always recommended to consult the manufacturer's installation instructions for any specific hardware or setup requirements.

Product Details

This set includes 12 High Energy Die Cast Aluminum Roller Rocker Arms from COMP Cams, designed for Chevrolet Small Block V8 engines. These are a solid choice for street use and moderate racing applications, offering an affordable way to get improved performance from your engine's valvetrain. They feature a 7/16" stud diameter and a 1.5 ratio.

The rocker arms themselves are made from die cast aluminum, which is stronger and lighter than stock cast iron components. This construction helps reduce overall engine weight and allows for a stiffer rocker arm that can handle more open spring pressure, up to 550 lbs. The design includes a needle bearing fulcrum and a roller tip, which significantly cuts down on friction compared to traditional sliding rocker arms. Less friction means lower oil temperatures, which can lead to better engine response and a slight increase in horsepower.

Snap rings are used to keep the trunnion and bearings securely in place, ensuring durability. If you're rebuilding the top end of your Small Block Chevy and looking for a well-built, cost-effective upgrade, these roller rockers are a popular option.
