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

A spragless torque converter uses a different internal mechanism than a traditional converter with a sprag. In mud racing, this design is often favored because it can handle higher torque loads and is generally considered more robust under extreme stress, potentially offering better longevity in demanding conditions.

What does the 4000 RPM stall speed mean for my vehicle?

The 4000 RPM stall speed indicates the engine RPM at which the torque converter will typically start to effectively transfer power to the transmission. This rating is suited for engines that produce significant power at higher RPMs, allowing you to build engine speed before launching for maximum acceleration.

Are there any special installation considerations for this torque converter?

Yes, as a specialized racing component, it's important to ensure your Ford C4 transmission is properly built and capable of handling the stresses associated with mud racing. Always refer to the manufacturer's installation instructions and consider consulting with a transmission specialist for optimal setup.

Product Details

What you get with this FTI Performance torque converter is a complete, well-built unit designed specifically for the demands of mud racing. This converter features a 9.5-inch diameter housing and a 10.5-inch bolt circle, with 26 splines to connect to your transmission. It's built to handle a 4000 RPM stall speed, meaning it's set up to let your engine rev up before the torque converter engages the drivetrain, giving you that crucial launch power off the line.

This isn't just any torque converter; it's a spragless design. That means it relies on a different internal mechanism for torque multiplication, which is often preferred in high-stress racing applications like mud bogging because it can handle more abuse and doesn't have a weak point like a traditional sprag. The construction uses solid materials throughout, aiming for durability under extreme conditions. The 4000 RPM stall rating is tuned for engines that make their power higher in the RPM range, helping you get the most out of your setup when you need it most. This converter is a serious piece of equipment for anyone looking to maximize their C4 transmission's performance in a mud racing environment.

When installing this converter, remember it's a specialized part for a specific type of racing. Ensure your C4 transmission is in good condition and properly set up to handle the power and stress. It's always a good idea to consult with your transmission builder or FTI Performance directly if you have any questions about compatibility with your specific engine build or transmission modifications. This converter is not CARB approved and cannot be shipped to California.
