SBF Sportsman R/A's - 1.6 Ratio 3/8 Stud

The PRW Industries SBF Sportsman R/A's - 1.6 Ratio 3/8 Stud are precision roller rocker arms specifically engineered for small block Ford engine builds. This complete set of 16 rocker arms is designed for builders and engine shops looking to enhance performance in street or moderate racing applications.

Each rocker arm features a roller tip design that minimizes friction against the pushrod and reduces wear on valve stems, ensuring durability during operation. The 1.60:1 mechanical advantage ratio balances valve lift responsiveness with valve spring loading, making these arms suitable for naturally aspirated and moderately boosted applications.

These rocker arms are compatible with stock and aftermarket small block Ford heads, making them an excellent choice for those restoring classic engines or building performance street engines. Properly matching the rocker arm ratio to your camshaft profile and intended RPM range is essential for achieving optimal valve timing and preventing valve float.
