Eaton 915A568 Detroit Truetrac 11.5" 30 Spline Differential for American Axle

This worked perfect for my 11.5 differential. Company was great to work with! I have yet to drive my truck but install was easy, given the correct tools

This unit was relatively easy to install, Went into Chevy 3500 dually 11.5 AAM replacing a the open carrier as shown in the photo. I reused the bearings and ring/pinion. This kind of unit was originally designed by Quaife in England and is a Auto-Torque Biasing, not a true Limited Slip. Works great in mud/snow/trails all while towing 12,000 Lbs.

So far it has been good 6000 miles , it locks at any speed , it is so so on ice at 75 MPH , just keep it in 4 WD and all is GOOD

Very good quilty. Feels about twice as heavy ad factory. Smooth and quiet. Could have been packaged better but nothing was damaged.

It looks good. I have not installed yet. So I cannot give a good review.

I love the eaton true Trac locker assembly. Quick easy instal and engages smoother and quicker then the factory rear diff. Quick shipping my truck was only down for a week sat-sat.

Got this diff for my 06 gmc 2500 what a difference compared to my factory diff with 180,000mi. I drive on dirt/gravel roads on a daily basis and the traction is extremely noticeable. So smooth dont even know it's there. I might be crazy but Im pretty sure my mpg went up about 2 mpg!

The rite part the first time
