Billet Flexplate SFI LS/LSX 168-Tooth 6-Bolt

The Billet Flexplate SFI LS/LSX 168-Tooth 6-Bolt by ProTorque is designed for serious LS and LSX engine builders who prioritize reliability and precision in high-performance drivetrain applications. This flexplate acts as a crucial mechanical link between the engine's crankshaft and the automatic transmission torque converter, effectively transmitting horsepower while absorbing rotational shock loads.

Constructed from solid billet aluminum, this flexplate offers superior stress distribution compared to weaker OEM stamped steel designs, minimizing the risk of catastrophic failure under extreme conditions. The 168-tooth configuration is standard for LS-family engines compatible with popular automatic transmissions, including TH400, 4L60E, and 4L80E. The SFI certification indicates that it meets safety standards for racing applications, having been rigorously tested for durability.

Ideal for LS engine swaps, high-horsepower street builds, and competition vehicles, this flexplate provides the strength necessary to handle elevated boost levels and aggressive power adders. While installation typically requires engine removal in many vehicles, specific requirements may vary based on the vehicle model, so it's essential to consult your vehicle's specifications before proceeding.
