Before you rule out the diesel springs.. also consider if you'll be adding a heavier bumper, winch or what not to the front end. If you're getting them for a 3/4T diesel, I don't think they'd be that bad.. You're adding some extra weight, have room to add even more accessories, and since you don't have as much weight compressing them.. you'll probably pick up a little more height as well.
