What is the benefit of nitriding these rocker arms?

Nitriding infuses nitrogen into the steel's surface, significantly increasing its hardness. This leads to improved wear resistance for longer life and better lubricity, which helps reduce friction.

Do these rocker arms come with everything needed for installation?

This set includes adjusting nuts and pivot balls where required for installation. Always refer to the manufacturer's installation instructions for any additional hardware or procedures.

Can I use these with a very aggressive camshaft?

These rocker arms feature a long slot design, which allows them to accommodate camshafts with higher lift than stock. They are specifically recommended for stock or COMP Cams High Energy camshafts.

Product Details

If you're rebuilding the top end of your engine, these COMP Cams Hi-Energy rocker arms are a solid option for a range of Chevrolet and GMC big block applications from the mid-60s through the mid-90s, including models like the C10 Pickup, C2500 Suburban, and even the Pontiac LeMans. 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 set features a 1.7 ratio, which is great for engines using stock or COMP Cams' own High Energy camshafts, especially if you're running a camshaft with higher lift than stock, thanks to the long slot design.

What really sets these apart is the nitriding process. This treatment infuses nitrogen into the surface of the steel, making it much harder. This improved surface hardness means better wear resistance, both when the engine is new and over the long haul. It also helps with lubricity, reducing friction. These are well-built steel rocker arms that are ready for higher spring pressures and hardened pushrods, making them a dependable choice for your engine build.
