FTI 9In Custom SST Series Torque Converter - Aluminum Stator With Diode - Turbo Spline

FTI Performance is known for building reliable racing components, and their SST Series torque converters are a popular choice for racers who need a solid balance between street drivability and serious track performance. This 9-inch SST converter, part number SST89-6T, is custom-built for your specific application, featuring an aluminum stator with a mechanical diode and a turbo spline. It’s designed for those who want a well-mannered car on the street but need it to perform when you hit the drag strip.

This converter is built with serious racing in mind. It comes standard with a steel anti-ballooning plate to help keep things stable under load, a forged billet front cover for strength, and billet stator caps. You'll also find hardened turbine and impeller hubs, plus triple Torrington bearings for smooth operation and durability. The furnace brazing and TIG welding ensure these critical joints are strong and won't fail when you're pushing your vehicle hard.

This particular SST converter is set up for a turbo spline and is compatible with THM400 and THM350 transmissions. While it's designed for performance, keep in mind it's not CARB approved and cannot be shipped to California. If you're building a street/strip car and need a torque converter that can handle the demands of both, this FTI converter is a well-built option.
