The Gold Race rocker arms are manufactured from heat-treated billet aluminum extrusions, and CNC machined to exacting tolerances. They feature Crane's exclusive Quick-Lift technology and employ heavy-duty precision-ground steel needle bearings, a heat-treated steel roller tips. They can handle up to 700 lbs of open spring pressure, and come complete with adjustable locking nuts.
