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: GM 10.5" Chevy 14 bolt Rearend (with full float bolt in axles and removeable pinion support)

Axle Spline: 30

Compatible Gear Ratios: 3.42-4.10 (3-series) (also fits aftermarket "thick" gear)

  1. Great Product 5 Star Review

    Posted by on 19th Sep 2021

    I installed this Posi unit with a set of 4.56(thick) gears and everything went together perfectly, in a 2001 10.5 14 bolt. install was easy, as this was the first differential I have ever done.


  2. Great OEM quality Eaton Detroit helical posi! 5 Star Review

    Posted by on 24th Feb 2021

    Easy to install, remove the old carrier, install the ring gear and bearings and it is ready to install! Fits perfectly in place of the original 10.5" 14 bolt carrier. The function is perfect for my 1 ton dually and both tires kick in when 1 is spinning faster.
