Pro Series Flexplate SFI 29.1 SBC BBC 168T

The Pro Series Flexplate SFI 29.1 SBC BBC 168T by PRW Industries is a precision-engineered flexplate designed for serious engine builders and hot rodders running small-block or big-block Chevrolet powerplants. This component sits between your engine and transmission, transmitting torque while absorbing vibration and damping shock loads during hard acceleration and shifting. Whether you're building a street machine, strip-ready racer, or comprehensive restomod, a quality flexplate is non-negotiable for reliable power transfer and longevity.

This 168-tooth flexplate meets SFI 29.1 safety certification, the industry standard for racing and high-performance applications where component failure carries real consequences. The SFI specification ensures the flexplate can withstand extreme torque loads and thermal cycling without cracking or warping. PRW's Pro Series construction uses premium ductile iron that balances strength with controlled flex characteristics—too rigid and you risk cracking; too flexible and you lose efficient power delivery. The 168-tooth design provides optimal starter engagement geometry while maintaining concentricity critical for smooth transmission operation and minimal driveline vibration at highway speeds and launch.

Weighing 8.19 lbs with compact overall dimensions, this flexplate is compatible with both small-block and big-block Chevrolet engines paired to automatic transmissions. Installation requires engine-out service in most applications, making it ideal for comprehensive engine rebuilds, transmission swaps, or performance upgrades where access is already available. This is the choice for builders who refuse compromise on driveline integrity—from weekend warriors tackling 400+ horsepower street builds to dedicated racers running consistent power at the strip.
