Th350/Th400 Tork Master

The TH350/TH400 Tork Master from B and M AUTOMOTIVE is a heavy-duty transmission torque converter designed for drivers who demand maximum power transfer and reliability in high-performance driving conditions. Whether you're building a street machine, drag racing platform, or restoring a classic American muscle car, this converter bridges the critical gap between engine output and transmission input, ensuring your vehicle launches hard and maintains consistent power delivery across the RPM band. Mechanics and enthusiasts trust B and M AUTOMOTIVE components for their proven engineering and durability in both stock and heavily modified powerplants.

The TH350/TH400 Tork Master utilizes precision-engineered stator geometry and optimized blade design to minimize slippage and heat generation while maximizing torque multiplication at launch. This converter features a stall speed matched to aggressive cam profiles and higher-displacement engines, allowing you to build boost and RPM before engagement for superior acceleration off the line. The robust internal construction handles sustained high-load cycles without cavitation or wear, critical for drivers running consistent hard launches or sustained performance driving where thermal stress on traditional converters would cause premature failure.

Ideal for TH350 and TH400 transmission applications, the Tork Master converter performs exceptionally in vehicles ranging from daily-driven performance cars to weekend drag racers and high-horsepower street builds. Installation is straightforward for any mechanic familiar with standard torque converter replacement procedures, and the converter pairs seamlessly with stock or modified transmission internals. The 33.04-pound assembly mounts directly to your existing flexplate, making it a bolt-in upgrade that delivers measurable improvements in launch feel, acceleration response, and overall drivetrain efficiency without requiring transmission rebuild or extensive modification.
