I'm going to do the swap out in my 01 XJ, so what year explorer and model/package should I be looking for when in search of the 8.8 with 4:10 gears? Also if limited slip diff or not. All help is greatly appreciated..

 

95-01 explorer/mercury mountaineer look at the tag on the axle if it says c355 then its open diff and 3.55 gear,Now if it says L410 that means locker 4.10.Or you can open the driver door and look at the axle code you want D2 or R7 both are 4.10 with a locker.

 

Thanks for this info, it should get me started.
