SBF H/E Alum. R/A's - 1.6 Ratio 3/8 Stud

The SBF H/E Alum. R/A's - 1.6 Ratio 3/8 Stud from COMP CAMS represents a complete rocker arm solution engineered for small block Ford engine builders and enthusiasts seeking reliable valve actuation. This 16-piece set delivers the precision geometry and durable construction required for high-performance applications where consistent valve lift and timing directly impact engine efficiency and power output. Whether you're assembling a street performance engine, a vintage hot rod, or a competition build, these aluminum rocker arms provide the mechanical advantage and longevity that serious builders demand.

Built with a 1.60 ratio geometry, these high-energy die-cast rocker arms amplify cam lobe lift by 60 percent, allowing smaller cam profiles to produce larger valve openings and extended duration benefits. The full roller design minimizes friction and wear on both the pushrod and valve stem interfaces, reducing parasitic losses and extending component life under sustained RPM and load. The 3/8-inch stud mount anchors securely to small block Ford cylinder heads, ensuring stable geometry and eliminating deflection that could compromise valve train accuracy. Aluminum construction keeps reciprocating mass low, a critical factor in reducing inertial stress at higher engine speeds and improving overall valvetrain response.

This rocker arm set is purpose-built for small block Ford platforms and pairs seamlessly with matching pushrod lengths and stud girdles. Technicians and builders working on 221, 260, 289, and 302 cubic inch engines will appreciate the immediate bolt-on compatibility and the elimination of guesswork in valve train assembly. The complete 16-piece configuration covers a full engine set, streamlining procurement and ensuring matched geometry across all cylinder pairs. Installation requires standard pushrod adjustment and spring pressures appropriate to your cam selection; consult your engine builder or cam manufacturer for final valve lash specifications to guarantee optimal performance and longevity.
