Pro Series Flexplate SFI 29.1 82-95 SBF 157T

The Pro Series Flexplate SFI 29.1 82-95 SBF 157T is a purpose-built flexplate engineered for serious small-block Ford enthusiasts and performance mechanics who demand reliability during high-rpm operation and engine swaps. This component serves as the critical mechanical bridge between your crankshaft and torque converter, absorbing shock loads while transmitting power to the automatic transmission. Whether you're building a carbureted street engine, restoring a classic Ford, or assembling a modern EFI conversion in a vintage chassis, this flexplate delivers the structural integrity and SFI certification required for safe, durable operation.

Manufactured by PRW Industries Inc., a trusted name in aftermarket engine components, this flexplate features SFI 29.1 certification—the industry standard for sanctioned racing and high-performance street applications. The 157-tooth ring gear provides optimal engagement with modern starter motors, while the robust construction resists cracking and warping that can occur under sustained boost or aggressive launch loads. At 7.745 lbs, it delivers the necessary mass and rigidity without excessive weight penalty, critical for engines spinning above 6,500 rpm. The precision-engineered design ensures concentricity with your small-block Ford crankshaft, eliminating vibration and transmission converter slip that compromise efficiency and longevity.

This flexplate is ideal for mechanics and builders working with 1982–1995 small-block Ford engines paired with automatic transmissions, from stock C-4 and AOD applications to modern overdrive units. Installation requires proper torque specification and alignment with your existing crankshaft flange and torque converter; use a dial indicator during fitment to verify runout and prevent converter damage. Its SFI certification makes it race-legal for sanctioned events, while its robust engineering ensures streetable reliability under daily driving, weekend cruising, or track duty.
