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

The PRW Industries SBC Sportsman R/A's rocker arms deliver proven performance for small block Chevy engine builders and enthusiasts seeking reliable valve train geometry. This complete set of 16 rocker arms features a 1.5 ratio design with 3/8 inch stud mounting, engineered to maximize lift characteristics while maintaining precise valve actuation across a wide RPM range. Steel construction with roller tip design reduces friction and wear on valve stems, a critical consideration in high-performance and competition applications where durability and consistency directly impact engine longevity and power output.

The 1.5 ratio specification means these rocker arms multiply camshaft lift by 1.5 times, translating to increased valve opening distance compared to 1.2 or 1.3 ratio alternatives. This geometry is ideal for cam profiles designed to maximize cylinder head flow without excessive spring pressure or structural stress. The 3/8 inch stud mount configuration provides secure, repeatable fastening on compatible small block Chevy cylinder heads. Roller tip construction eliminates point-load contact with pushrod ends, distributing force across a larger surface area to reduce deformation and extend component life in both street and track environments. Natural steel finish requires proper lubrication and maintenance to prevent corrosion.

This set serves engine builders restoring classic small block Chevys, racers tuning stock or modified engines, and technicians upgrading worn or original equipment rocker arms. Buyers should verify compatibility with their specific cylinder head casting and confirm that valve spring pressures and pushrod geometry match the 1.5 ratio lift multiplier. The complete 16-piece set covers a full small block Chevy complement, eliminating the need for mixed-brand or mismatched rocker arms that compromise valve train precision.
