SBC Sportsman R/A's - 1.52 Ratio 3/8 Stud

The SBC Sportsman R/A's - 1.52 Ratio 3/8 Stud rocker arms are designed specifically for small-block Chevy engines, catering to weekend warriors, restoration enthusiasts, and street engine builders who prioritize reliable valve actuation and consistent lift ratios. This set includes 16 rocker arms, providing the precision geometry necessary for optimal engine performance.

Engineered by PRW Industries, these sportsman-grade rockers feature a 1.52:1 lift ratio that effectively multiplies cam lift, enhancing valve opening characteristics. The roller tip design reduces friction and wear on the pushrod interface, which can extend component life and minimize parasitic losses compared to traditional ball-socket designs. Constructed from steel with a natural finish, these rocker arms are built for durability and longevity.

These rocker arms are ideal for engine builders looking to upgrade from original equipment, restorers of classic muscle cars, or enthusiasts seeking improved valve control for both carbureted and fuel-injected small-block Chevy engines. The three-eighths inch stud mounts ensure a secure attachment to the cylinder head, providing stability during high-rpm operation.
