FTI Performance

Does your car have an automatic transmission and more power than it left the factory with? FTI Performance makes torque converters and automatic transmissions built to handle the extra power and launch harder. Here you’ll find converters for street cars and drag racing, complete transmissions and parts for popular American automatics such as the TH400, Powerglide and 4L60E.

American specialist in automatics and torque converters

FTI Performance is an American brand specialising in the drivetrain behind the engine on cars with automatic transmissions. The focus is on torque converters and complete transmissions, mainly for GM and Ford platforms, from classic muscle cars to modern LS and Coyote cars and trucks. The brand is well known in drag racing, but much of the range is aimed at street cars, where you want a converter that suits the camshaft, gearing and weight without making the car unpleasant to drive every day.

FTI Performance’s key products

Torque converters are at the core of the range. They come with different stall speeds, so the engine can reach its power band before the car moves off, and with lock-up for modern electronically controlled transmissions. For street cars there are series that combine a higher stall speed with good driveability, while the race versions are built for hard launches. FTI Performance also offers complete, upgraded transmissions for the TH400, Powerglide and 4L60E, among others, plus spare parts and accessories. See each product for transmission and engine.

Frequently asked questions

What does stall speed mean on a torque converter?

Stall speed is the engine speed the engine can reach before the converter really starts transferring power to the transmission. A higher stall speed lets the engine get into its power band and gives a stronger launch, especially with a bigger camshaft.

Which FTI Performance converter should I choose?

It depends on the engine, camshaft, rear axle ratio, tyre size and the weight of the car. Check the description on each product and feel free to contact us with your details, and we’ll help you find a suitable stall speed.

How do I know if a part fits my car?

Contact us with your car’s make, model, year and preferably engine code, and we’ll help you find the right part.
