GM TH350/TH400 Torque Converter 3500 Stall

The Hughes Performance GM TH350/TH400 Torque Converter 3500 Stall is engineered for street and strip enthusiasts who demand responsive acceleration and improved launch characteristics from their classic Chevrolet transmissions. This torque converter is purpose-built for drivers upgrading their powertrains for high-performance applications, ensuring it can handle the torque multiplication and heat load that comes with increased power.

Constructed from high-quality billet aluminum, the Hughes converter is designed to provide maximum durability under extreme operating conditions. Its precision-machined internals minimize slippage and heat generation compared to traditional stamped steel designs. The 3500 RPM stall speed allows for effective torque multiplication until the engine reaches 3500 RPM, delivering a firm bite off the line while maintaining efficiency at cruise.

This converter fits both TH350 and TH400 transmissions, making it an excellent choice for muscle car restorations or modern restomods. Proper cooling system support and synthetic transmission fluid are recommended to manage the increased thermal demands of performance driving, ensuring longevity and reliability in high-horsepower applications.
