SBF Roller Rocker Arms - 1.6 Ratio 7/16 Stud

The SBF Roller Rocker Arms - 1.6 Ratio 7/16 Stud from PRW Industries are designed for small-block Ford enthusiasts looking to enhance their high-performance or stroker engines. These roller rocker arms serve as a significant upgrade over stock stamped steel rockers, improving valvetrain geometry and reducing friction across the RPM range.

The 1.6 ratio design allows for a valve lift that is 1.6 times greater than that of a 1:1 rocker, which helps to increase airflow and improve cylinder filling without necessitating a more aggressive camshaft profile. The roller design minimizes friction losses that are common with traditional rocker arms, thereby reducing parasitic drag and enabling more horsepower to reach the wheels.

These rocker arms are particularly beneficial for engine builders upgrading small-block Fords with aftermarket or ported cylinder heads, especially in applications that require higher RPM limits or more aggressive valve timing. Installation requires standard rocker arm studs and adjustable pushrods to ensure proper lash and geometry.
