Picked up my 2016 Durango R/T AWD today after having the 3.45 front and rear differentials installed. Here is some information and my initial thoughts.
I got my differentials off of ebay. I paid $365 for the front differential and I paid $215 for the rear differential. That’s shipped. They were both used. The front one had 36k miles. The rear one had 50k miles. All they needed was fluid, seals and everything were in great shape.
I got them on ebay from terryvilleautoparts and okautopartsms respectively. Both came with 6 month warranty.
Part numbers for mine (there are many numbers for the same differentials. Just cross reference online):
Front: 68263986AA
Rear: 68060039AF
Be sure that they are 3.45 differentials and that the rear says 230mm 9.06 somewhere because it has to be 230mm and a 9.06 to fit the r/t Durango.
Highway Driving:
60MPH rpm increased by about 200rpm in 8th gear
80mph rpm increased by about 100rpm in 8th gear
this won’t kill your gas mileage.
0-60 Improvement: .05 second improvement (went from a 5.55 to a 5.50)
1/4 Mile Improvement: .13 second improvement (went from a 13.94 to a 13.81)
60ft improvement: .02 second improvement (went from a 2.08 to a 2.06)
