Review on Enhance Your Ride Comfort with AIR LIFT 59544 Ride Control Rear Air Spring Kit by Corey Listner

As others have said this is a good product for its intended purpose. If you are looking for "lift" then this is probably NOT what you are looking for. However, if you want to correct for sag due to weak leaf springs, this will bring you back up to original height and keep you there under load. I can't substantiate the 2000 pound claim, but I put an 800 pound Harley in the back and at about 50 psi my truck sits where it used to sag. My headlights dazzled oncoming traffic, and in response, the high beams kept hitting me; that fixed it too. Bolt a 2006 Ford F150 Lariat with a 6-inch lifter.
