FTI 9.5in Ford C4 Spragless Mud Racing Converter - 10.5in BC - 26 Spline - 3000 Stall

This FTI Performance 9.5-inch torque converter features a spragless design, meaning it doesn't rely on a traditional internal sprag for lockup. Instead, it uses a unique multi-plate clutch system that engages directly with the transmission input shaft. This setup is built for the extreme demands of mud racing, where consistent, strong engagement under heavy load is critical. The 10.5-inch bolt circle and 26-spline input shaft are specifically chosen to mate with Ford C4 transmissions commonly found in drag racing and mud bogging applications.

The spragless configuration is a key advantage for mud racing because it eliminates a potential failure point under shock loads. The multi-plate clutch system provides a more robust and durable engagement, capable of handling the high torque multiplication and sudden impacts characteristic of off-road racing. This converter is rated for a 3000 RPM stall speed, which is optimized for engines built for maximum power in the mid-range, allowing for a strong launch off the line when you hit the throttle. The internal components are well-built to withstand the intense heat and stress generated during competition.

When installing this torque converter, ensure you properly fill it with transmission fluid before mating it to the transmission pump. It's also crucial to confirm that your C4 transmission is built to handle the increased power and torque this converter is designed for. This unit is not CARB approved and cannot be shipped to California due to emissions regulations.
