Detroit Truetrac Differential
The Detroit Truetrac is a helical-gear style performance differential that maximizes wheel traction and enhances driving and handling characteristics.

The Truetrac operates as a standard or open differential under normal driving conditions, allowing one wheel to spin faster or slower as necessary. When a wheel encounters a loss of traction or the terrain changes, the gear separation forces take effect and transfer torque to the high-traction wheel. The helical-shaped gears mesh with increasing force until wheel spin is slowed or completely stopped. When the vehicle exits the low traction situation, the differential resumes normal operation.

Operation of the Truetrac is smooth, quiet and automatic. The unit will engage without any driver knowledge or action required. It also has no wearable parts and requires no maintenance, meaning less time in the garage and more on the road.

5 of 5 Rear Differential install September 3, 2014
Reviewer: Kent Newsom from APO AE, NY United States  
Again I was really apprehensive about purchasing the Eaton Truetrac  for a delivery and install in the states when I was stationed overseas.  I bought the 4.56 gears and Eaton truetrac limited slip differentials after the people at justdifferentials convinced me that they wouldn't ship the wrong parts to my brother in law for installation before my jeep was sent to me overseas.  I told them that I couldn't be there to handle any problems that might pop up with wrong parts and they assured me that the correct parts only would be sent.  After they arrived my brother in law installed everything without a hitch and told me they couldn't have fit better or functioned better.  Hats off to justdifferentials for outstanding service and commitment to customer needs!
