Billet Flexplate - SFI GM LS1 - 168 Tooth

The Billet Flexplate – SFI GM LS1 – 168 Tooth is a precision-engineered component designed for LS-platform engines requiring maximum reliability during high-horsepower applications. A flexplate is the critical link between your engine's crankshaft and automatic transmission, absorbing torsional vibration and transmitting power while protecting the transmission from shock loads. This component is ideal for street machines, track cars, or performance daily drivers.

Constructed from billet aluminum, this flexplate offers superior strength-to-weight characteristics compared to traditional stamped designs. The 168-tooth configuration matches factory LS1 torque converter applications precisely, and the SFI certification ensures it meets Society of Automotive Engineers safety standards. This is critical for vehicles that are raced or driven hard, as flexplate failure can lead to expensive repairs.

With a weight of 7.7 lbs, this component adds minimal rotating mass while significantly improving durability and power handling capability across the entire engine RPM range. It is essential for any LS1-powered vehicle running an automatic transmission and increased power output, ensuring reliable performance in demanding conditions.
