SBF Roller Rocker Arm - 1.6 Ratio 3/8 Stud

The Scorpion Performance SBF Roller Rocker Arm with 1.6 Ratio and 3/8 Stud is engineered for serious small-block Ford engine builders seeking reliable, race-grade valvetrain geometry. This full roller design replaces traditional stamped steel rockers, delivering consistent mechanical advantage across the RPM band—critical when you're targeting repeatability at the track or maximizing street performance without compromise. Whether you're building a competition 302, 351W, or fuel-injected 5.0L, this component addresses the fundamental need for precision rocker geometry that won't deflect under load.

Constructed from aluminum and finished in blue anodize for corrosion resistance, the 1.6 ratio geometry means your pushrod travel multiplies at the valve tip—specifically, for every 1 inch of pushrod lift, the valve opens 1.6 inches. This ratio strikes the balance between maximum valve opening and adequate pushrod preload, preventing valve lash issues that plague softer stampings. The full roller tip bearing design minimizes friction at the valve stem interface, reducing parasitic drag and improving flow efficiency compared to flat-faced alternatives. The 3/8-inch stud mount anchors securely to your cylinder head, offering rock-solid clamping without the flex inherent in bolt-through designs on older blocks.

These rockers suit any small-block Ford engine platform—290 to 351 cubic inches—and pair seamlessly with aftermarket cylinder heads, cam profiles, and high-lift applications where standard rockers fail. Installation requires proper valve lash adjustment and compatible pushrods; confirm your rocker stud length and pushrod geometry before ordering. Weighing just 0.52 pounds each, they're lightweight enough for street machines yet durable enough for bracket racing and road course duty. Order as singles or complete sets to rebuild both banks of your SBF.
