Installation took approximately 8 hours instead of 2 as stated in the instructions. The hardest part was positioning the frame support so that there was no interference. In fact, in my case, both the driver and the passenger faced increasing problems. I spent most of my time cutting out each spacer to get the exact fit. The kit included everything you need for installation, including metal hardware. At about 50 psi I saw about 0.5 inch of extra lift with no load. You can really feel how much more solid the truck feels when pumped up.
