What is the primary function of rocker arm shafts?

Rocker arm shafts are crucial components in your engine's valvetrain. They serve as the pivot point for the rocker arms, which in turn open and close the intake and exhaust valves based on the camshaft's action.

Are these shafts sold individually or as a set?

These are sold as a set of rocker arm shafts, designed to replace the stock shafts in your engine's cylinder heads. You will receive the necessary shafts for your application in one package.
