As I've stated in the FAQ, it is not as necessary to do on a 4-door as the drive shafts are quite long. If you have an automatic, you may want to get a new front shaft as its smaller diameter will give you a bit more clearance between it and the auto skid. Other than that, the factory shafts seem to do quite well.

Well, as I say in the FAQ...

However, in order to do this, you will need to buy a set of rear adjustable upper control arms so that you can properly set your pinion angle... As far as the front goes, if you have an automatic transmission, you should really consider replacing the drive shaft with a double cardin U-joint style unit as well as the diameter of aftermarket shafts tend to be considerably narrower and will not come into contact with the skid plate. An alternative to this would be to remove the automatic transmission skid plate or cut out a notch along the edge to prevent the drive shaft boot from making contact with it.
