Description

The Eaton Detroit Truetrac is a helical gear-style limited slip differential that maximizes traction and enhances driving and handling characteristics. It operates as a standard differential under normal driving conditions, allowing for smooth, quiet operation. When wheel slippage occurs, the Truetrac’s helical gears mesh to bias torque to the wheel with the most traction, providing improved grip without the need for clutches, cones, or springs, which typically wear out over time. This design makes it a durable and maintenance-free solution for enhanced traction.
