SBC Sportsman R/A's - 1.5 Ratio 7/16 Stud

The SBC Sportsman R/A's - 1.5 Ratio 7/16 Stud by PRW Industries are engineered rocker arms designed for small-block Chevrolet engines, ideal for performance enthusiasts building street machines, bracket racers, or high-RPM drag applications.

These rocker arms feature a 1.5:1 lift ratio, which effectively multiplies the camshaft lift by 1.5 times, optimizing valve lift for enhanced power delivery and engine efficiency. The robust 7/16-inch stud configuration ensures a secure mounting interface that withstands high valve spring pressures, making them suitable for various camshaft types, including solid and hydraulic roller camshafts.

Engine builders and racers in Sportsman classes will appreciate the reliability and performance these rocker arms provide, allowing for improved valve timing and flow characteristics without the need for extreme cam durations.
