Pro Series Flexplate SFI 29.1 SBF 157T

The Pro Series Flexplate SFI 29.1 SBF 157T from PRW Industries is a premium flexplate engineered for small-block Ford engines requiring SFI 29.1 certification. This component serves as the critical interface between your engine's crankshaft and torque converter, absorbing rotational vibration and absorbing shock loads during acceleration and deceleration. Whether you're building a high-performance street engine, a drag strip competitor, or upgrading an aging stock setup, a quality flexplate is non-negotiable for reliability and longevity.

This flexplate is manufactured to strict SFI 29.1 safety standards, meaning it has passed rigorous testing for burst resistance and structural integrity under extreme torque conditions. The 157-tooth design is specifically matched to small-block Ford engine configurations, ensuring precise starter engagement and eliminating potential misalignment issues. PRW's Pro Series construction incorporates premium materials and precision balancing to minimize vibration transmission to the transmission and drivetrain, which is especially critical in forced-induction or high-displacement builds where stock components fail. The lightweight yet robust design at 6.55 lbs reduces rotational inertia without compromising durability, a key advantage when tuning for faster throttle response and reduced parasitic losses.

This Pro Series Flexplate SFI 29.1 SBF 157T is ideal for enthusiasts and shops rebuilding or upgrading small-block Ford engines destined for automatic transmissions. Installation is straightforward—simply bolt it to your crankshaft flange using the OEM bolt pattern—making it suitable for both DIY projects and professional builds. If you're performing a transmission swap, upgrading to an aftermarket converter, or simply replacing a worn original flexplate, this SFI-certified component provides the safety assurance and performance reliability that serious builders demand. Verify tooth count and bolt pattern compatibility with your specific engine block before purchase to ensure a perfect fit.
