What is a spragless torque converter and why is it used in mud racing?

A spragless torque converter does not have an internal one-way clutch (sprag). This design is often preferred in mud racing because the sprag can be a point of failure under extreme stress. By eliminating it, the converter is generally more robust for high-demand applications.

What does the 3800 stall speed mean for my vehicle?

The 3800 stall speed indicates the engine RPM at which the torque converter will typically lock up and transfer power most efficiently. A higher stall speed like this is generally suited for performance applications, allowing the engine to rev higher before the converter fully couples, which can be beneficial for launching off the line in racing.

What transmissions does this FTI torque converter fit?

This FTI Performance torque converter is designed to fit transmissions identified as TF-8 and 727. These are common Mopar automatic transmission designations.

Product Details

This is the FTI Performance 9.5-inch Spragless Billet Mud Racer Series torque converter, designed for serious off-road competition. It features an aluminum stator and is built with a 3800 RPM stall speed, making it a strong choice for mud racing applications where consistent performance and durability are key. You'll receive the torque converter itself, ready for installation into compatible transmissions.

FTI Performance builds these converters with a billet cover for added strength and uses furnace brazing and TIG welding for solid construction that can handle the demands of racing. The spragless design means there are no internal one-way clutches to fail, which is a common point of breakage in high-stress off-road environments. Triple Torrington bearings are used to ensure smooth operation and support the rotating assembly under load.

This torque converter is designed to fit a wide range of vehicles, including many classic American Motors, Chrysler, and Dodge models from the 1970s and 80s, such as the American Motors Hornet, Chrysler Cordoba, and Dodge Aspen. It's a well-built component aimed at racers looking for a reliable torque converter that can withstand the rigors of mud racing.
