On 98 and newer Rangers the 4x4 Rangers got a Torsion bar front suspension. Also the Edge and Trailhead 2wd models got Torsion bar front suspensions, which can be lifted just the same as a 4x4 (crank the t-bars). I've heard a rumor that Sport models have it too, but I'm not sure.
If it's A-arms and coils you may be able to stuff a 2" lift coil in there. Or you have to go with a spindle lift or a different set of A-arms and coils. Fabtech was the brand that made a bunch of that sort of stuff, not sure if they're still making it or not.
In the rear, standard 2wds are the same as a 4x4 minus the 2" lift block. But Edge and Trailhead 2wds got lift blocks, IIRC. IMHO, lift blocks are a poor choice for lifting. I'd rather do a Belltech 6400 drop shackle and/or changing/modifying the leaf spring pack.
I did a custom leaf pack in my Ranger, when I first put it in I had gained about 4" out back, but after it settled in I figure it sits at a solid 2" or slightly more. And when I'd load it down it wouldn't sag to the bump stops like before, so it worked well for me. I could change the pack around and probably gain up to 5" out of the pack and another 2" with a shackle if I wanted. But I've retired it from regular work duty so I'm not sure what I'm going to do with it yet. (lift or lower)
