What Comes With What?
For swapping into a Ranger, a 4.0L Ranger donor is the best choice, as it is in most cases a bolt-in affair. Explorers and others will work, check the notes below for specifics. Pre-1990 Rangers will need minor driveshaft modifications, or the driveshaft from the donor, as the driveshaft flange on pre-90's is smaller. All axles listed below have a 5 on 4.5 bolt circle.
