Looking for an axle that will bolt in. It has a 8.25 rear end with 3.55 gears and want to change to 3.9. I know the 9.25 will need the u bolts and plate to mount. What years and models should I look for? 8.25 or 9.25 is OK just looking for the gear ratio.
The Jeep axles may not have the same shock attachment points like the Dakota does.
Durango from 98-03 have different shock attachment points as well.
Any 97-04 Dakota rear axles are direct swap. The best is going to be the rear disc optioned trucks to grab from and they are fairly common. 8.25 vs. 9.25 means the difference of whether or not you want the higher payload and towing capacity.
