Not being familiar with the Skyjacker lift, only knowing the similarities between the two trucks, I think some parts will and some parts won't. (How's that for an accurate answer?! Dead Link Removed )
Seriously, for the rear, if there are lift blocks, they won't work. Add-a-leaves probably aren't strong enough (the Explorer is heavier than a Ranger). Also, the spring lengths might be different.
For the front, there is a good chance that everything will fit properly.
Call Skyjacker and ask them what will fit - also, you could probably buy any additional pieces that you need (instead of the whole kit).
