I have the 2" Thuren kit with Fox Shocks and I added the rear shocks. Truck is perfectly level at 2". Ride quality after the install is amazing. In fact, the ride quality was so much better my wife even noticed. If you do it yourself (which I did) you'll need to make sure you have two jack stands (not harbor freight) and two floor jacks. This part is important and it is noted in the instructions. Make sure you take it to a good alignment shop, the Tire Shop/Alignment place will not do you any favors. The trucks are simple to align but you need to make sure your caster is set correctly. I made the mistake of taking mine to Tire Shop/Alignment shop, I had to go back 3 times as I felt something was off. In speaking with the person aligning the truck I figured out he was going by the alignment machine and would not do anything outside of making adjustments the machine recommended. He was trying to align the truck to stock specs. I ended up talking to a jeep guy in town and asked him where went for alignments and used his guy. Problem solved.
