The Flexplate Ford 157 Tooth by Quarter Master is a lightweight steel flexplate engineered for Ford engines requiring internal balance compensation. This component serves as the critical mechanical interface between the engine crankshaft and the automatic transmission torque converter, enabling smooth power transfer while accommodating the engine's rotating mass characteristics.
The 157-tooth count is precisely calibrated for specific Ford engine and transmission combinations where internal balance is required by the engine design. Steel construction combined with lightweight engineering reduces rotational inertia, which improves throttle response and reduces mechanical losses in the drivetrain. Internal balance compensation means the flexplate's mass distribution is specifically calculated to work with the engine's harmonic characteristics rather than relying on external weight distribution, delivering superior balance integrity across the full RPM range. Weighing 4.78 lbs, this flexplate maintains strength while minimizing parasitic drag on engine performance.
This flexplate is intended for enthusiasts and technicians rebuilding or restoring Ford automatic transmission engines where OEM or near-OEM specifications are required. Quarter Master is recognized in the drivetrain component market for precision manufacturing and exact fitment standards. Buyers performing engine swaps, rebuilds, or restorations where transmission compatibility is critical should verify their specific Ford engine displacement and transmission model against the 157-tooth specification before ordering to ensure correct fitment.
Flexplate tooth count directly determines torque converter engagement and must match both engine and transmission specifications. Incorrect tooth count results in converter misalignment, transmission slippage, and severe drivetrain damage. The Quarter Master 157T flexplate is manufactured to dimensional and balance tolerances that ensure proper meshing with the torque converter and crankshaft, making it a core component in any Ford automatic transmission assembly.
