Billet Alum Flywheel SBF 302 157t 50oz in bal

The RAM CLUTCH Billet Aluminum Flywheel SBF 302 157-Tooth 50oz external balance is a precision-engineered component designed for small-block Ford engine builds requiring SFI 1.1 certified rotating assembly components. This aluminum flywheel combines lightweight construction with the structural integrity needed for high-horsepower applications, delivering measurable improvements in engine response and acceleration characteristics over cast-iron alternatives.

The 157-tooth ring gear matches common starter motor configurations, while the 50-ounce external balance specification is critical for matching your engine's harmonic balancer and crankshaft balance weight. The replaceable friction surface design extends service life—wear material can be resurfaced rather than replacing the entire component, reducing long-term costs. Weighing 15.2 pounds, the aluminum construction significantly reduces rotational inertia compared to traditional cast flywheels, resulting in quicker engine spin-up, improved throttle response, and reduced parasitic power loss.

This flywheel is engineered for small-block Ford platforms—302, 289, 351W, and similar displacements—in street performance, drag racing, and restoration builds where engine efficiency and response matter. SFI 1.1 certification ensures it meets safety standards for high-rpm operation and competition environments. Proper balance with your specific crankshaft assembly is essential; verify your engine's balance specification matches the 50-ounce external balance rating before installation to avoid vibration and premature bearing wear.
