My question is whether you plan on taking the truck off the pavement. If so, i have had better luck with Superlift. They just seem to hold up a little better. It might be to your benefit to pay the extra bill to get the Superlift. Like I said, I've had better luck with Superlift. My truck has a 12" Superlift on it right now. It rides a little rough, but that's to be expected with 12" springs. The only problem I have right now is my steering Drag link is not for a lifted truck so all the joints are bad. Make sure your kit has one with it, or you can buy one separately.
