I've done it on my rodeo. My spring pack was sagging pretty badly, so I decided to leave my add-a-leaf in. As it is, its resting on the add-a-leaf, so if I took it out my springs would invert. It first netted me somewhere around 8" of rear lift. I threw about 400 lbs of cinder blocks in the rear and that brought it down to a more reasonable 6". I've been slowly removing the blocks as it settles.

I first cranked the front until it was sitting on the bumpstops, at about 4.5" lift. It gets a bit <img src="/forums/images/graemlins/zombie.gif" alt="" /> going over bumps though, so I cranked it down just a little bit so its at least not sitting on the bumpstops.

So about 4.25" front, 6" rear, it has a definite rake to it, doesn't look rediculous though. I still plan on redrilling the front spring hanger to lower the rear some, then I can dial the front down too.

Yes, still have the two piece driveshaft. It vibrates real bad from 0-5 mph then surprisingly, evens out. Still has enough extension for full flex.

Overall, I would not recommend it, unless you are planning on SAS soon.
