I just got off the phone with the Rancho technical expert, 734 384-7804, and he advises that there is no application of the 9000X shocks for 03, one ton, 4X4's. I had planned on putting a set on front and rear to haul a rather heavy camper. Anybody know if there is a good replacement shock that is adjustable that will stand up to a heavy load? Or has anybody put a set of Ranchos on a 03 even though they claim not to have a set that fits? Thanks for the help.
