Dana 30 Detroit TrueTrac - FRONT 27 Spline (3.73 & Up)

Sku: DTT 912A585

Part Number: DET 162SL60A
Brand: Eaton Detroit

The Dana 30 27 spline Detroit Truetrac uses a patented design of parallel axis, planetary helical gears, to provide a smooth and quiet, automatic division of torque. The Truetrac performs like an open differential under normal conditions, and automatically transfers torque to the wheel with the highest traction when required. On wet, muddy, icy or loose terrain, imbalanced gear forces automatically transfer power to the wheel with the highest traction.


- Helical worm gear design, no clutches to wear out
- Can transfer up to 3.5 times more torque to high traction wheel
- Smooth and quiet operation
- Limits wheel spin-out and improves handling
- ABS Compatible
