I have the 3 1/2 inch MetalCloak short arm, long travel kit and love it. First, it came with everything and was easy to install. One part came missing a rubber grommet and MetalCloak took care of it very quickly. I have been running the lift now for 3 years. I have no sagging springs and everything still works great. It gives a firm ride, handles great on the freeway even at 80mph and performs amazingly off road. I have driven it in heavy rain at 70-80mph, through deep snow both freeway and trails, and on forest service roads in the mud. I don’t have squeaks or rattles. Several friends gave me grief about the expense but now that they see there are no problems and no “little issues “ that crop up they are impressed.
