installation started a bit difficult. First you need to remove the bumper beams from the frame. The screws were well rusted in the clamps so they had to be coaxed! Bulgarian, mounts, hammer, but after 3 hours they ran out. The rest of the installation was pretty easy and completed in a couple of hours. They work great! This is my fourth set of Airlifts and I would recommend them to anyone looking to upgrade their rear suspension!
