Description

The Eaton Detroit Truetrac limited-slip differential uses helical gear-based traction technology to automatically transfer torque to the wheel with the best traction. This enhances mobility, stability, and handling, providing up to 3.5 times more torque transfer. It operates smoothly and quietly without driver action. It has no wearable parts and requires no maintenance, contributing to a lower overall cost. It is engineered to keep both wheels in drive mode, maximizes traction, unlocks for different wheel speeds, and eliminates traction problems.
