What makes this torque converter spragless, and why is that good for mud racing?

A spragless torque converter does not have a one-way clutch (sprag). This design is inherently stronger and can handle more abuse, making it ideal for the extreme demands of mud bogging where sudden, high torque loads are common.

What is the purpose of the anti-ballooning plate?

The steel anti-ballooning plate is integrated into the converter's design to help prevent the unit from expanding excessively under high heat and pressure. This helps maintain the converter's structural integrity and consistent performance during intense use.

What vehicles does this torque converter typically fit?

This converter is designed for GM vehicles with TH350 and TH400 transmissions. Examples include many Chevrolet C/K series trucks and SUVs, as well as various Buick and Cadillac models from the 1980s and early 1990s. Always confirm your specific transmission model.

Product Details

If you're building a mud bogger or a weekend warrior that needs serious grunt off the line, this FTI Performance MR Series torque converter is built for the job. It's specifically designed for GM TH350 and TH400 transmissions and is engineered to handle a wide range of horsepower, from 400 up to 1,200 hp. This converter is a spragless unit, meaning it doesn't have a one-way clutch, which makes it incredibly strong and ideal for the harsh conditions of mud racing. It's a popular choice for those who want a tough converter that can take a beating without breaking the bank.

FTI Performance has put some solid components into this converter to ensure its durability. You'll find a forged billet steel front cover for strength, a billet spragless center, and a hardened flanged impeller hub. It also includes a steel anti-ballooning plate, which helps keep the converter from expanding excessively under extreme load. This spragless design is key for mud racing applications where you need maximum engagement and a robust unit that won't fail when you hit the throttle hard. The aluminum stator is designed for a 4000 RPM stall speed, giving you that hard-hit launch you're looking for.

This converter is designed to fit a wide variety of GM vehicles equipped with TH350 or TH400 transmissions, including popular models like the Chevrolet C10, Chevrolet K5 Blazer, and Buick Regal from the 1980s. It's a direct replacement for many applications, but it's always a good idea to double-check your transmission model to ensure a perfect match. While it's built tough for racing and performance use, please note it is not CARB approved and cannot be shipped to California.
