Air Lift 57131 LoadLifter 5000 Air Suspension Kit

The box was dropped outside my gate and the box was broken and parts were out on the ground, it’s a terrible kit and not for a ford E450 motorhome !!, and the heat shield would not work properly, it’s a terrible terrible design, and I had to return it to Amazon, and this kit should not even be sold , in fact it’s possibly one of the worst things that I have ever seen in my life, and very dangerous to install too under a vehicle . I would advise you get the 88242 kit that mounts outside of the frame , between the frame and the tyre a much better design for a ford E450 motorhome .The lower bracket sits above the brake line , and a crazy dangerous design, and if you don’t set it up correctly, you can damage your brakes/ damage a brake line with brake fluid in it, pay for the outside frame mounting kit, that bolts to the frame and then to the leaf springs, way way better and safe too !!, and unfortunately I am not just a pretty face !!, this kit is a nasty awful design, and don’t even think about buying it!!.

Great quality kit. Kind of tough to install in my driveway with the motorhome on the ground. The key is to compress the bags as much as possible. I used zip ties. I am happy with this product. At 80PSI it lifted the back of my 29'class C over 2".

Very easy to install on my E450 RV, even though I am 70 years old. Raised rear of vehicle +2 inches @ 60 psi. Transferred some weight to front end for better drivability. Highly recommended.

It was a vast improvement to my ride it was so easy to install took me a little longer because it was heavy duty equipment

This was purchased to replace an original but worn out system.I ordered a model specific application, but the fit was muchworse than the original system it was replacing.Maybe the manufacturing was "out sourced".
