FTI 9.5in Ford C4 Spragless Mud Racing Converter - 10.5in BC - 26 Spline - 3800 Hard Hit Stall

If you're building a Ford C4 transmission for serious mud racing, you know how crucial a robust torque converter is. This FTI Performance spragless converter is built to handle the extreme demands of that environment. It's designed to put the power down when you need it most, giving you that hard-hitting stall speed that mud racers rely on to get moving.

This converter features a 9.5-inch diameter housing and a 10.5-inch bolt circle, making it a solid choice for many C4 applications. The 26-spline input shaft is designed to match specific transmission setups, ensuring proper engagement. What really sets this converter apart for mud racing is its spragless design. Unlike traditional converters with a one-way clutch (sprag), this spragless unit allows for bi-directional rotation. This means it can handle the intense, back-and-forth forces common in mud racing without the risk of damaging a sprag, which can be a weak point under extreme load. The advertised 3800 RPM stall speed is engineered for a hard hit, meaning it's intended to launch the vehicle aggressively off the line, providing the immediate torque multiplication needed to dig through tough terrain.

When installing a high-stall converter like this, it's important to ensure your engine's cooling system is up to the task, as higher stall speeds can generate more heat. Also, confirm that your C4 transmission is properly built to handle the increased torque and stress that this converter will put through it. This FTI converter is a well-built component designed for a specific, demanding application.
