SBC Ultra Gold R/A's - 1.6 Ratio 3/8 Stud

The COMP Cams SBC Ultra Gold R/A's - 1.6 Ratio 3/8 Stud are precision roller rocker arms designed for small-block Chevrolet engines that demand maximum reliability and consistent performance. These rocker arms are ideal for street machines, bracket racers, and high-RPM applications, providing repeatable results across thousands of engine cycles.

Featuring premium investment-cast construction and roller bearing technology, the Ultra Gold rocker arms significantly reduce friction at the valve tip. This design enhances valve control, allowing for faster opening and closing, and ensures consistent lift across the RPM range. The 1.6 ratio design increases valve lift by 6.67% over the stock 1.5 ratio, improving flow potential and cylinder head efficiency without the need for cam grinding or port work.

These rocker arms are perfect for enthusiasts looking to upgrade from stock stamped steel rockers, especially when combining a performance cam, ported heads, and higher-lift valve springs. The 3/8-inch stud mount secures directly to standard SBC cylinder head bosses, ensuring robust valvetrain geometry that can withstand load and vibration, making them critical for engines with aggressive cam profiles or extended race duty.
