What is the main benefit of using aluminum rocker arms with a roller tip?

Aluminum construction makes these rockers lighter while maintaining strength. The roller tip and needle bearing fulcrum significantly reduce friction compared to stock sliding rockers, which can lower oil temperatures and improve engine response.

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

These COMP Cams High Energy rocker arms are designed to withstand up to 550 lbs of open spring pressure, making them suitable for street use and moderate racing applications.

Do these rocker arms come with the necessary studs and hardware?

This set includes the rocker arms themselves. It is designed for use with 7/16" studs, which are not included and should be verified for compatibility with your specific engine build.

Product Details

Starting with a 1.7 ratio and a 7/16" stud diameter, these COMP Cams High Energy Roller Rocker Arms are built with a die cast aluminum body. This aluminum construction offers a better strength-to-weight ratio than stock steel rockers, making them lighter overall while still being strong enough for street use and moderate racing applications. They fit a wide range of Chevrolet Big Block engines, including popular models like the 396, 402, 427, and 454.

Inside, you'll find a needle bearing fulcrum and a roller tip. This design significantly reduces friction compared to the sliding contact of factory rockers. Less friction means lower oil temperatures, which can lead to improved engine response and a small bump in horsepower. The die cast aluminum body is also designed to be stiffer, helping to increase valve lift and withstand the demands of performance use, handling up to 550 lbs of open spring pressure. Snap rings are used to keep the trunnion and bearings securely in place.

These rocker arms are a cost-effective way to upgrade your engine's valvetrain. They are designed to fit many Chevrolet vehicles from the late 1960s through the mid-1990s, such as the Impala, Chevelle, and C10 Pickup. For installation, ensure you are using the correct 7/16" studs and compatible valve springs.
