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 professional-grade valve train components engineered for small block Ford engine builders seeking precise valve lift and reliable performance. These roller rocker arms are designed for high-rpm applications where consistent lift curves and reduced friction are critical to engine efficiency and durability. Available as a complete set of 16 units, they eliminate the guesswork in matching rocker geometry across all valve positions.

The 1.6 ratio designation means each rocker arm multiplies camshaft lift by a factor of 1.6, translating cam motion into precise valve travel while the full roller design minimizes friction and heat generation compared to traditional shaft rockers. Constructed from billet aluminum and finished in blue anodize, these arms combine lightweight construction with corrosion resistance and professional appearance. The 7/16-inch stud mount system provides secure fastening to standard small block Ford cylinder head configurations, and the roller design reduces parasitic drag on the camshaft, freeing up horsepower for usable output.

Street, strip, and race engine builders rely on these roller rocker arms when rebuilding or upgrading SBF valve trains for increased reliability and performance consistency. The complete 16-piece set ensures symmetrical installation across all intake and exhaust positions without mixing components or ratios. Installation requires proper pushrod length measurement and preload adjustment to optimize rocker geometry and prevent valve train noise or clearance issues. Whether you're restoring a classic small block or building a modern high-output engine, these PRW roller rocker arms deliver the durability and precision that professional engine builders demand.
