How does the Detroit Truetrac differential improve traction?

The Truetrac uses helical gears that automatically bias torque to the wheel with more grip. This means if one wheel starts to slip, the differential directs more power to the other wheel that still has traction, helping you move forward.

Does this differential require special fluids?

No, the Detroit Truetrac is designed to be maintenance-free and does not require any special lubrication or friction modifiers. You can use standard gear oil suitable for your vehicle's differential.

What specific axle dimensions does this differential fit?

This Eaton Detroit Truetrac differential is built for axles with a 1.12-inch axle shaft diameter and 27 splines. It is also designed for rear differentials that use a 7.5-inch ring gear.
