Review on 🚗 AIR LIFT 59551 Rear Air Spring Kit for Enhanced Ride Control by Robert Wood

I have a half ton truck and tow it almost every day. These bags made a big difference when towing. There is now almost no sag under loads that used to lower my truck 5 inches in the rear. The trailer no longer rocks on the freeway. Since installing them I've towed £11,000 for 40 miles with no problems. But I had one bag where the inlet valve blew off because the cheap plastic lock nut at the top of the bag had come loose. I hit a bump and somehow blew off the nut, which in turn blew off the intake valve. I think those locknuts should be brass or stainless steel, but the Air Lift has replaced the bag without question. (That was 11,000 lbs ago by the way)
