Eaton Detroit Truetrac differentials use a patented design of parallel-axis planetary helix gears to provide a quiet, automatic splitting of torque. They perform like a limited-slip differential under normal driving conditions, automatically transferring torque to the wheel with better traction when ground conditions warrant. These replacement units are available for dozens of axle applications.

Q:

I have a 1996 gmc 1500 with a 4:56 gear in the rear. Will this product still work? I obviously have drum brakes in the back.

Asked by MATTHEW on July 18, 2016

A:

As long as your current diff is a 10 bolt. & your axles are 30 spline. I replaced my 28 spline axles w/ Moser's 30 spline.

Q:

Would this fit my 1996 2 door tahoe?

Asked by DANIEL on November 18, 2017

A:

Yes, If you were to click on the "Find out if this fits your application" window on the right it lets you know the applications that it fits. 8.5" and 8.6" are nominal and the earlier ones were 28 spline while later (like yours) is 30 spline as long as it is the original rear axle assy.

The PERFECT replacement for the G80 this differential is by far the best thing I've installed on my truck. No more one tire fires, and the design, and build quality tops OEM. 100% bulletproof! Pure engineering here.. no wearable parts. no little springs, no ticking time bomb. 100% Made in Detroit goodness!

Very happy with it

Summit RacingSummit Racing Verified Purchase

DTL-913A481
I was expecting something more similar to a factory Posi unit, but I actually like this better. On the road you don't even notice it working, other than the improved traction. On a loose surface it locks up solid like it should. There is no noise or jarring when it engages or dis-engages. Need to make sure you get the proper bearings if you have the GM 10 bolt 8.6 axle. ...read more

Install this in 2004 Chevy

DTL-913A481
I installed this Tru trac in my 2004 Silverado. It was my first time working on a rear end. I did not change the ratio. It went real good. A video on you tube was a great help. I was surprised they said to not use synthetic fluid. I put 2000 miles on, check the fluid, and there was no metal in the bottom, so I call it a success.
