TH350/400 11in Torque Converter

The TH350/400 11in Torque Converter from TCI is a specialized transmission component designed primarily for performance applications in vintage muscle cars, classic hot rods, and performance trucks. This 11-inch converter replaces the factory unit to enhance throttle response and optimize power delivery, making it suitable for street and strip use.

Torque converters serve as hydraulic couplings between the engine and transmission, controlling how early the engine can load the drivetrain. TCI's focus on flow dynamics and clutch pack design aims to improve fluid coupling efficiency while minimizing heat generation and slippage during acceleration. The precision-balanced components help reduce vibration and extend the longevity of the clutch pack under repeated loading cycles.

This torque converter is particularly beneficial for vehicles with aggressive cam profiles or turbocharged engines, as it allows the engine to reach optimal RPM before the transmission locks. Buyers should ensure compatibility with their existing transmission model, as TH350 and TH400 converters are not interchangeable with newer overdrive transmissions.
