Just finished this truck up. Specs are... Michigan Metal Works control arms with drop spindles. 3/4 ton brake rotor/hub, bearings and seals. Slam RE7 bags up front. I built the rear 3 link setup with Firestone 2107 bags and bilstein shocks. Viair 480 dual pack, two 7 gallon aluminum tanks, Accuair VU4 manifold, Accuair switchspeed controller, ect. I also had Todd at The Interior Shop redo the interior.
