SBC Ultra Gold R/A's - 1.5 Ratio 3/8 Stud

The SBC Ultra Gold R/A's - 1.5 Ratio 3/8 Stud from COMP CAMS is a precision-engineered rocker arm assembly designed for serious small-block Chevrolet performance builds. These aluminum roller rocker arms cater to builders and mechanics who require reliable valve actuation under high-RPM conditions and aggressive cam profiles.

The 1.5 rocker ratio geometry provides a mechanical advantage over the cam lobe, translating smaller lobe lift into greater valve travel for enhanced cylinder breathing and scavenging efficiency. Constructed from high-strength aluminum and featuring precision roller bearings, these rocker arms minimize friction losses and reduce parasitic drag on the crankshaft, which is crucial for maximizing horsepower.

Ideal for engine builders working on small-block Chevrolet applications from 265 to 400 cubic inches, the Ultra Gold rocker arms deliver durability and accuracy to keep the valvetrain synchronized and responsive across the power band. Their robust 3/8 stud diameter ensures superior clamping force and vibration damping, making them suitable for various performance scenarios.
