When the front end sags under heavy gear or towing weight, this setup keeps things level and steady. The Air Lift LoadLifter 5000 Ultimate air springs add up to 5,000 lbs of load-leveling capacity to your front axle, helping distribute weight evenly and maintain safe headlight aim. With pressure adjustable from 5 psi to 100 psi, you can dial in just the right amount of support for steering control and braking under load.
Each air spring has a closed-cell urethane jounce inside that takes the edge off bumps and jolts. These built-in jounces kick in when air pressure alone isn’t enough, absorbing shock and keeping you from bottoming out. They engage smoothly and progressively—the more weight you add, the stiffer they get—so the ride stays comfortable and controlled even on rough terrain or when cornering hard.
This system is made for serious use. The 2-ply, fabric-reinforced rubber air springs handle heavy loads day after day, while high-strength Zytel nylon endcaps resist corrosion better than steel. Air Lift’s exclusive roll plates protect the bags from damage and increase load capacity by spreading out the surface area. Together they extend spring life and keep your suspension performing reliably through heat, cold, and long hauls.
Mounting these air springs doesn’t require fancy equipment—just basic tools and a little driveway space. The kit installs between your truck’s frame and leaf springs with included brackets, hardware, air lines, and manual inflation valves. Once installed, you can inflate each side independently for side-to-side leveling or equally for front-to-back balance. Add an optional compressor system later if you want in-cab control without stepping outside to adjust pressure.

I have left them on and they are still functional with what they do. I still put boards under my front tires to drive up on if the site is off a lot for when my jacks are deployed.

You mentioned that the lower brackets were not strong enough and had to be replaced. I wanted to see if you would be able to send a picture of the location? Was this installed on your 2002 Workhome W Series RV?
Do you have a question about this Vehicle Suspension?
