Overall install took me about 4 hours.Important to note that you should remove the rear coil springs for easiest access, and you must cut off the rear bump stop then grind down any sharp edges from the old bracket.The install itself really wasn't difficult but meticulous trying to get some bolts in tight locations.Instructions are well detailed and easy to follow, along with recommended torque specifications. The air line came with plenty of slack to run two individual hoses to the rear bumper and was very easy to connect.I'm happy with the quality.
