Product Details

When you're rebuilding a Chevrolet Big Block engine, especially one from 1965 to 1987, you want components that restore performance and quiet things down. This set of COMP Cams Hi-Energy rocker arms is designed to do just that. They replace worn-out stock rocker arms, which often develop noise and slop over time, giving your engine a much smoother and quieter operation. You'll get the rocker arms themselves, along with adjusting nuts and pivot balls where needed, so you have the essential pieces for the job.

These rocker arms are well-built from steel and feature a 1.7 ratio, which is a common upgrade that can help improve valve lift. They also have a long slot design, making them suitable for use with camshafts that have higher lift than stock, whether you're using a stock camshaft or one from COMP Cams' High Energy line. This makes them a solid choice for engine rebuilds where you want to bring the valvetrain back to life or give it a slight performance boost.

This set is specifically for Chevrolet Big Block engines that use a 7/16" stud diameter. They fit a wide range of Chevrolet trucks and vehicles from the late 80s and early 90s, like the C1500, C2500 Suburban, and K3500, ensuring a direct fit for many popular applications.
