I'd go with a body kit. I already have a 3/4 ton (rougher riding) but I put one ton springs underneath it and it lifted it about 2 inches, but it beats the crap out of you unless you're on a super-smooth road. I'm seriously considering lowering it back down to stock height so it'll ride better. I like the lift, but not enough to let those one-ton springs beat me and my truck to death. I got a good taste the other day in an industrial area I had to goto where the roads are super-rough from all the big trucks in and out of there, man that sucked!
