What is the benefit of nitriding on these rocker arms?

Nitriding is a heat-treating process that increases the surface hardness of the metal. For these rocker arms, it improves their durability and longevity, especially when used with higher spring pressures or hardened pushrods.

Do these rocker arms come with everything needed for installation?

Yes, the rocker arms include the necessary adjusting nuts and pivot balls where required for installation on compatible Chevrolet Small Block engines.

Can I use these rocker arms with a camshaft that has more lift than stock?

Absolutely. These rocker arms feature a long slot design specifically to accommodate camshafts with higher lift than stock, making them a good choice for mild performance upgrades.
