Turbo TH350 TH400 9.5" High Stall Torque Converter 4100-4500 Billet Front Hub Big Shot

 Torque Converter TH350 TH400 w/ Dual Bolt Pattern & Billet Hub Plate

With heavy-duty Billet Front Hub

Stall RPM: Small Block 4100-4500 / 4300-4700 Strokers 

Designed with the street/strip application in mind, this Turbo 400 / Turbo 350 torque converter benefits more radically prepared street machines (those with performance cams, aftermarket carbs and higher compression ratios) to bring the launch RPM in line with the performance enhancements. 

Perfect torque converters for the street & strip. These TH400 converters are "tight" which allows the best street manners and allows the engine to flare when standing on the accelerator peddle. Best of both worlds. 

Transmission Specialties is renowned worldwide for the highest quality racing torque converters. As the innovators for the industry, we know what works and what doesn’t.

The TSI 9.5” 245MM Torque Converter is the perfect converter for the racer with 300-1000HP. This converter is known in the industry as many names such as 9”, 9.5” 245MM and 10”. Don’t get confused, they are all the same, just different ways of advertising the same product. Only the highest quality hand fabricated or billet front covers, furnace brazed pumps and turbines are used in our converters. Our stator designs are revolutionary and will give you lightning-fast launches while still coupling hard on the top end. 

The mechanical diodes we use at TSI are the strongest in the industry and have been tested for over a decade in the most demanding applications!
