COMP Cams Rocker Arms Ultra Gold SBC

The Comp Cams Ultra ARC Aluminum Series Rocker Arms increase engine power, improve valvetrain stability, and enhance oiling efficiency. Their extruded design—developed using FEA analysis—creates a stronger, stiffer rocker body without adding unnecessary weight. The ARC series rocker arms feature an Arced, Recessed, Contoured design delivers an optimal strength-to-weight ratio. Backed by a Lifetime Warranty—buy them once and use them forever. Engineered for applications running up to 700 lbs of open spring pressure. Perfect for initial break-in, these Ultra-Gold ARC rockers for Chevrolet Small Blocks reduce valve lift by limiting the rocker ratio to 1.3. A great asset to engine builders who prefer to limit the valve lift over removing an inner spring.
