SBF Ultra Gold R/A's - 1.6 Ratio 7/16 Stud

The SBF Ultra Gold R/A's - 1.6 Ratio 7/16 Stud from COMP CAMS represents a precision-engineered rocker arm assembly designed for serious small-block Ford builders and engine builders who demand maximum performance and durability. Built for high-RPM applications, these rocker arms address the critical weak points in stock and mid-range Ford engine packages: inadequate valvetrain geometry, excessive deflection under load, and marginal strength at elevated cylinder pressures. Whether you're assembling a street-performance 347, a vintage race engine, or a modern fuel-injected stroker, this ultra-gold treatment and optimized 1.6 ratio delivers the valvetrain precision required for consistent power delivery and longevity.

The 1.6 rocker arm ratio is engineered to increase valve lift and duration across the entire RPM band, optimizing cam profile utilization and improving volumetric efficiency without replacing your existing camshaft. The 7/16-inch stud specification ensures compatibility with standard small-block Ford cylinder head drilling patterns while maintaining the structural rigidity necessary for sustained high-RPM operation. COMP CAMS' ultra-gold finish provides superior corrosion resistance and reduces friction at the rocker-to-pushrod interface, extending component lifespan and reducing parasitic losses. The precision-forged steel construction withstands the dynamic loads and harmonic frequencies generated by aggressive power curves, eliminating the chatter and wear associated with marginal factory geometry.

These rocker arms are ideal for engine builders, restoration specialists, and performance enthusiasts upgrading small-block Ford heads on the 260, 289, 302, 351W, and 5.0 platforms. Proper installation requires verification of pushrod length and valve clearance adjustment after assembly—critical steps that prevent valve-to-piston interference and ensure optimal cam lift transfer. The 7/16-inch stud diameter is standard for most aftermarket and factory small-block Ford heads; however, confirm your cylinder head's rocker stud specification before ordering. Installation onto existing studs is straightforward for experienced engine builders, making this an excellent mid-level valvetrain upgrade that delivers measurable gains in power consistency and engine reliability.
