SBF Roller Rocker Arm - 1.72 Ratio 7/16 Stud

The SBF Roller Rocker Arm – 1.72 Ratio 7/16 Stud is a precision-engineered component designed for small-block Ford enthusiasts seeking reliable valve train upgrades. Manufactured by Scorpion Performance, this roller rocker arm replaces traditional cast iron pivot designs found on stock engines, enhancing valve actuation and minimizing friction across the RPM range.

The 1.72 ratio indicates that the valve lift is 1.72 times that of the camshaft lift, making it suitable for solid roller cam conversions and high-lift applications where stock rocker arms may restrict valve travel. The roller design significantly reduces sliding friction compared to conventional stamped-steel arms, which decreases wear on pushrods and camshaft lobes while allowing for sustained RPM capability without valve float. The heat-treated construction and precision tolerances ensure long-lasting durability under demanding conditions.

Mechanics and builders often choose Scorpion roller rocker arms when upgrading valve trains on classic Fords, street rods, or performance engines where OEM rockers have become a bottleneck. This rocker arm's 7/16-inch stud mount is the industry standard for small-block Ford platforms, ensuring straightforward installation into existing cylinder head configurations. Proper installation will require checking valve clearance to ensure compatibility with your specific engine setup.
