I know Rancho has a 4" lift for the 4X4, but is there a 4" lift in the works for the 2004+ 4X2's???

 

I would bet that the kits for the 4x4's will work on the 4x2's since the suspension is the same. I know this is true for HD Chevy 4x2 and 4x4 trucks and Jeep Grand Cherokee's. You could check with Rancho to find out for sure.

 

i talked to the guys from rancho at the 4wheelparts truck fest a couple weeks ago and they told me they discontinued their 2wd line of lifts

 

What's wrong with a 6" lift? That's what I have on mine plus a 3" body lift and I'd still kill for another couple inches.
