Okay. Thanks. Not sure I wasn't getting notifications. I'm leaning toward XD Monster 18" wheels with -12 offset and Toyo Open Country MT's in 275/70R18 tires which are 33.6" diameter x 11" wide. My shocks look brand new. They are Bilsteins with Arnott labels and a UPC with a number printed on it that says 29-4491, but I can't source the part number to tell what they really are.
Rear air bags are still there. Front stock shocks are still on, but the passenger side is leaking, so I'm looking at Fox coilovers for the front, but I might cheap out for now and go with adjustable Bilsteins and reuse the coils. I plan to just start with removing the running boards and adding the wheels and tires, so hopefully with this combo and moving the rear sensors I can get it to work. Once I can afford it, I'll do the bumpers, sliders and add a winch.
I would have gone with 17" tires for more meat, but I really love those monster wheels.
