FTI TH400 Valve Body Kit - Billet Aluminum - Reverse Pattern - External Transbrake - Sportsman Brake

When you open the box for this FTI Performance TH400 Valve Body Kit, you'll find the billet aluminum valve body itself, along with the external transbrake assembly. This kit is designed for racers looking to get the most out of their TH400 transmission, especially in drag racing applications where precise control and quick reaction times are critical. The reverse pattern setup means you'll shift through the gears in a familiar pattern, while the external transbrake allows for a powerful launch right off the starting line.

The heart of this kit is the billet aluminum valve body. Machining from a solid block of aluminum makes it incredibly strong and resistant to warping or cracking under the high pressures and temperatures found in racing transmissions. This robust construction is key to consistent performance lap after lap. The external transbrake is a significant upgrade, offering a more reliable and powerful way to hold the car at the line before launch compared to internal brake designs. This setup is geared towards the Sportsman racer who needs dependable, high-performance components that can withstand the rigors of competition.

Installing a performance valve body like this often involves a deep understanding of transmission internals. It's a job that requires careful attention to detail to ensure all the passages are clean and the components are seated correctly. While this kit provides the core components for a significant performance upgrade, it's important to ensure you have the necessary supporting parts and knowledge for a successful installation. Many racers pair this with a high-stall torque converter and a robust transmission cooler to handle the increased demands.
