SBF Roller Rocker Arms - 1.6 Ratio 3/8 Stud

The SBF Roller Rocker Arms - 1.6 Ratio 3/8 Stud from PRW Industries represent a premium upgrade for small block Ford engine builders and enthusiasts seeking maximum valve train efficiency. These full roller rocker arms are engineered for serious performance applications where precision valve actuation directly impacts horsepower, fuel economy, and engine reliability. Whether you're building a street engine, competition platform, or restoration project, roller rocker arms eliminate friction losses inherent in traditional stamped steel designs.

Constructed from billet aluminum and finished in durable black anodize, these rocker arms feature full roller design that reduces wear on pushrods and cam lobes while maintaining consistent valve lift throughout the engine's RPM range. The 1.6:1 ratio multiplies camshaft lift by 1.6 times, allowing you to optimize valve timing and duration without requiring a more aggressive cam profile. The 3/8-inch stud mount provides secure, repeatable positioning on small block Ford cylinder heads, and the complete set of 16 arms ensures uniform performance across all cylinders for balanced combustion and reduced vibration.

Professional engine builders and restorers choose PRW roller rocker arms for applications ranging from mild street motors to high-RPM racing engines. The roller design minimizes parasitic friction losses—typically recovering 5–10 horsepower compared to stock stamped rockers—while extending component life under sustained high-load conditions. Installation requires proper valve lash adjustment and compatible pushrod lengths; consult your engine builder or cylinder head manufacturer to ensure correct clearances and geometry before assembly. These arms deliver measurable improvements in valve response and repeatability that justify their investment for any serious small block Ford project.
