SBF S/S Roller R/A's - 1.6 Ratio 7/16 Stud

The SBF S/S Roller R/A's - 1.6 Ratio 7/16 Stud from PRW Industries is an essential upgrade for serious small-block Ford engine builders looking to enhance their valvetrain stability and performance. These roller rocker arms are designed for applications where precise valve actuation is crucial for maximizing horsepower, improving fuel efficiency, and extending engine longevity.

Engineered with a 1.6 mechanical advantage ratio, these stainless steel roller rockers reduce valve spring loads while accommodating aggressive cam profiles and valve lift characteristics that are vital for power production. The 7/16-inch stud mounting design ensures a secure fit to your cylinder head, providing the necessary lateral support for high-lift camshaft combinations. The roller-style contact surfaces minimize friction at the valve stem interface, which helps reduce parasitic drag losses and prolongs the service life of pushrods and lifters compared to traditional stamped-steel designs.

These stainless steel rocker arms are suitable for both street and race applications, making them ideal for small-block Ford (SBF) enthusiasts upgrading from factory components or OEM alternatives on 260-, 289-, 302-, 351W, and similar displacement platforms. Installation requires compatible components to ensure optimal performance and reliability.
