Review on 🚚 Air Lift 57399 LoadLifter 5000 Air Suspension System by Muhammad Balding

I installed this kit on a 2017 Ford F450 pickup for use when towing a heavy fifth wheel. My truck was already fairly level when towed before I installed the air springs, but I saw signs of sag. Even when it wasn't touching the ground, the ride was pretty harsh. After installing and selecting the right pressure, driving performance improved significantly. My F450 is VERY tall from the factory and the air springs can make this problem worse. If you have a tall truck and are relying on sag to tow height, the airbags may not deploy until you raise the trailer to accommodate your truck.
