I have x metal lowering kit on an 05 quad cab. Have just put on Caltracs which did help a little with vibration from pinion angle but I still need to raise the rear up when towing. Gary from x metal says just put air bags on. Well it does not seem to be that easy, I am in Dallas and have taken the truck to several reputable off road shop to get air bags installed and have had no success. They have all said with the setup I have on the truck there is no room for an air bag. Will someone please post a pic of the underside of your truck if you have airbags and x metal lowering kit installed? If you have a model # and manufacturer of the air system that would be appreciatted also. Thanks in advance.
