Product Description

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

Operation

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.

Performance

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.

Recommended oil is standard 80/90 weight (non-synthetic) (no additives).

Application: Ford 8.8" Rearend

Axle Spline: 31

  1. Very nice posi unit for the 8.8 5 Star Review

    Posted by on 8th Jun 2019

    Installed this in my 11 ford crown Victoria PI.
    Its nice to have complete traction to both tires now. Best I can tell its quiet in operation,my 3.90 gear whine a little bit, but she kicks sideways in a hurry when I want her to now.
    Overall pleased with the purchase I also have the same unit in my 92 f150 with 4.56 gears and 35" tires and it also performs great.
