Classic Performance Traction

Bring modern traction technology to your classic Ford vehicle with the Eaton Detroit Truetrac. Specifically designed for 31-spline axles with a 1.32-inch diameter, this limited-slip differential is the gold standard for enthusiasts restoring or modifying vintage Ford Broncos, Fairlanes, and Galaxies. By utilizing a helical-gear design, it eliminates the need for clutches, providing a smooth, maintenance-free experience.

Why Choose Detroit Truetrac?

  • Automatic Torque Bias: Instantly transfers power to the wheel with the most grip, preventing one-wheel peels.

  • Durability: Engineered to handle high-torque applications, perfect for built engines and larger tires.

Whether you are building a trail-ready Bronco or a street-dominating classic sedan, the Detroit Truetrac offers the reliability you need. Its helical gears ensure quiet operation, making it just as comfortable on the highway as it is capable on the dirt. This differential is a must-have for any serious drivetrain build, ensuring your power reaches the ground effectively.
