The COMP Cams rocker arm spacer is made from SAE 8620 chromemoly steel and replaces the spacers used with COMP's 1621 and 1622 Ultra Pro Magnum shaft-mount rocker systems. Rocker bodies are heat-treated for strength and stiffness, and the spacer supports the system's unique oiling that lubricates critical parts. A Big Block Chrysler version includes a special adjuster to accept conventional ball-ended pushrods.
