Pro Series Flexplate GM LS 168T SFI Quick Launch

The Pro Series Flexplate GM LS 168T SFI Quick Launch is engineered for serious LS engine builders and drag racing enthusiasts who demand lightweight, SFI-certified performance components. This flexplate serves as the critical link between your LS engine and transmission, replacing the factory cast iron unit with a precision-machined aerospace-grade aluminum design that reduces rotating mass and improves engine response.

Built for high-horsepower applications, the 168-tooth configuration ensures compatibility with modern LS engine blocks. The quick-launch design specifically minimizes converter lag in racing scenarios, translating to faster throttle response and improved power delivery during acceleration. Manufactured by PRW Industries Inc., this Pro Series flexplate combines aerospace-grade aluminum construction with CNC precision machining to deliver a product that weighs just 8.04 lbs—substantially lighter than OEM cast alternatives.

This flexplate is ideal for LS-swapped vehicles, naturally aspirated high-displacement builds, and turbocharged or supercharged engines. All mounting surfaces are precision-finished to ensure proper alignment and eliminate vibration issues common with inferior aftermarket units. With SFI certification, you can trust that it meets stringent safety standards for high-performance and racing environments.
