SBC Roller Rocker Arms - 1.5 Ratio 7/16 Stud

The SBC Roller Rocker Arms - 1.5 Ratio 7/16 Stud from PRW Industries is designed for small-block Chevrolet builds that aim to enhance valve train efficiency and reliability. These roller rocker arms are essential for engine builders and performance enthusiasts looking to maximize horsepower and RPM capabilities in both classic and modern SBC platforms.

By replacing traditional stamped steel arms with precision-engineered roller bearings, these rocker arms significantly reduce friction at the valve stem. The 1.5 rocker ratio geometry increases valve lift by 50% of the cam lobe rise, allowing for taller valve openings and improved cylinder head breathing. The roller bearing at the tip minimizes sliding friction, reducing wear on both the rocker and valve stem while enabling the valvetrain to operate at higher speeds with greater mechanical efficiency.

With a 7/16-inch stud mounting configuration, these rocker arms ensure proper alignment and provide the structural rigidity necessary for both street and strip applications. This specification is crucial for compatibility with your cylinder head casting and stud girdle setup. PRW Industries' commitment to high manufacturing standards guarantees concentricity and precise arm geometry, making these roller rocker arms ideal for those running tighter valve lash and higher spring pressures.
