COMP Cams High Energy Alum Rocker SBC 1.

Starting with a needle bearing fulcrum and a roller tip, these COMP Cams High Energy rocker arms are designed to reduce friction. This is a key detail because less friction means lower oil temperatures, which can lead to improved engine response and even a bit more horsepower. They're made from die cast aluminum, which gives them a good strength-to-weight ratio, making them lighter than stock but still strong enough for street use and moderate racing applications. The 1.5 ratio helps increase valve lift, and they're built to handle up to 550 lbs of open spring pressure.

These rocker arms fit a wide range of Chevrolet Small Block engines from 265 to 400 cubic inches, specifically those using a 3/8" stud. You'll find them commonly used in vehicles like the Chevrolet Camaro, Corvette, and Caprice from the 1980s and early 90s, as well as many C/K series trucks and SUVs. The aluminum construction is cost-effective and durable, offering a solid upgrade over factory stamped steel rockers. Snap rings are used to keep the trunnion and bearings securely in place.
