What does the nitriding process do for these rocker arms?

Nitriding infuses nitrogen into the steel's surface, significantly increasing its hardness. This makes the rocker arms more resistant to wear, which is especially beneficial for long-term durability and when used with higher lift camshafts.

Do these rocker arms come with everything needed for installation?

This set includes the rocker arms themselves, and also comes with adjusting nuts and pivot balls where they are required for proper installation on your specific engine.

Can I use these rocker arms with a stock camshaft?

Yes, these High Energy rocker arms are an excellent replacement choice for engine rebuilds using either stock or High Energy camshafts. They help eliminate noise and slop from older, worn stock rocker arms.

Product Details

If you're rebuilding a Chevrolet V8 engine, these COMP Cams Hi-Energy rocker arms are a solid choice for applications using stock or High Energy camshafts. They're designed to replace worn-out stock rocker arms, helping to get rid of that annoying noise and looseness that can develop over time. This particular set fits a wide range of Chevrolet V8 engines, including popular small blocks like the 265 through 400 cubic inch displacement, and also works with certain V6 engines. You'll find them on vehicles like the Chevrolet C10 pickup, Camaro, and Corvette from various years.

What sets these apart is the nitriding process. This treatment infuses nitrogen into the steel's surface, making it much harder. This improved surface hardness means better wear resistance, especially important when you're running higher lift camshafts, which these rockers accommodate thanks to their long slot design. They also handle higher spring pressures and hardened pushrods well, making them a durable option for engine builds that see regular use.

This set includes the rocker arms, and where required, adjusting nuts and pivot balls, making for a more complete replacement. They feature a 1.6 ratio and are set up for a 3/8-inch stud diameter, which is common for many Chevy V8s.
