Your experancing a problem that happends to every make of 4WD when lifted with big tires and driven off road, the big differance with a Kia is you are not wheeling the normal 4WD so no one make a reinforcement for them. I have wheeled a lot of differant vehicles and this Kia is as tuff as they come. Mine has been lifted for 12 year, 140,000 miles with no issues but I inspect mine alot. Build a reinforcement, weld it up and Keep wheelin.
