Switched to Icon multi rate rear leaf springs and the Eibach Pro Truck Stage 2R shocks (front coilovers and rear reservoirs).
The Icons with the additional leaf did a good job bringing the rear back up to stock height with all the weight on the back. I was a bit surprised how much of the coil adjustment the shop had to use to get the front up to level, though.
I was a bit nervous about the Adaptive Cruise Control and the parking sensors, but all seem to be working fine after relocation. Dixie 4 Wheel Drive in St George did a great job on this.
