When the front end starts to sag under a heavy load, steering and braking can get unpredictable. The Air Lift LoadLifter 5000 Ultimate air springs with internal jounce bumpers give you up to 5,000 lbs of load-leveling capacity. They help keep the front of your vehicle level from side to side and front to back so steering stays tight, braking feels consistent, and your headlights stay aimed where they should.
Rough roads and uneven pavement don’t have to make your ride harsh. Each air spring has a closed-cell urethane jounce inside that kicks in when air pressure isn’t enough to handle the load. The jounce absorbs shocks smoothly and progressively stiffens as weight increases, cutting down on bounce, sway, and bottoming out. Even if the air pressure drops, the jounce springs act as a fail-safe to keep your suspension protected until you can refill the bags.
Every load and road is different, so being able to tune your suspension matters. These air springs adjust from 5 psi up to 100 psi for precise support. Inflate both evenly for front-to-back leveling or set each side independently for off-center loads. Manual inflation valves are included, or you can pair the system with an onboard compressor (sold separately) for in-cab control while driving.
Longevity matters when you’re depending on your suspension for safety and control. The LoadLifter 5000 Ultimate uses 2-ply, fabric-reinforced rubber air springs with high-strength Zytel nylon endcaps that are lighter, stronger, and more corrosion resistant than steel. The urethane internal jounces need no maintenance and perform reliably in both hot and cold conditions. Along with heavy-duty brackets, hardware, and tubing included for install, the design is built for years of service under heavy-duty use.
This system mounts between your frame and leaf springs with hardware and air lines included. Once installed, just inflate through the manual valves to set your preferred pressure. The layout makes it ideal for DIY installation using basic tools—no complicated wiring or special equipment required—so you can get back on the road with balanced support under load.

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.

One year and many more miles on the road my air bags are still intact and performing better than expected. Thank you etrailer folks.

Airbags made a BIG difference,once I was able to get the right air pressure my 2015 Thor A class rides so much better!
