Extreme Duty Flexplate - SFI SBC/BBC 168 Tooth

The Extreme Duty Flexplate - SFI SBC/BBC 168 Tooth from PRW Industries is designed specifically for high-performance small-block and big-block Chevrolet engines that require reliable torque multiplication and vibration damping between the crankshaft and torque converter. This component is particularly beneficial for street machines, bracket racers, and daily-driven powerhouses, as it connects the rotating assembly to the transmission while managing extreme loads and shock.

PRW's Extreme Duty design features premium nodular iron construction and SFI (SFI Foundation, Inc.) certification, indicating it has undergone rigorous testing to withstand catastrophic failure during high-rpm operation and detonation events. The flexplate effectively absorbs harmonic vibrations from the crankshaft while accommodating the torque converter's rotational requirements, helping to prevent issues like cracked ring gears and converter hub damage that can occur with inferior units.

At a weight of 8.33 pounds, this flexplate maintains rigidity without adding excessive weight, and the precisely machined 168-tooth ring gear ensures accurate starter motor mesh for reliable engine cranking. The SFI rating is crucial for applications such as bracket racing and forced-induction builds, where detonation or over-rev conditions pose significant risks. Engine builders and mechanics looking for a dependable flexplate will find this product to be an excellent choice for their performance needs.
