Heavy loads can make the rear of your truck sag, throwing off your steering, braking, and headlight aim. The Air Lift LoadLifter 5000 Ultimate air helper springs provide up to 5,000 lbs of load-leveling capacity to keep you level when hauling or towing. By pairing these air bags with your existing suspension, you reduce stress on factory components and maintain even weight distribution across all four wheels. Whether you’re loaded down or pulling a trailer, your truck stays steady and predictable on the road.
Rough roads and heavy loads don’t have to mean a harsh ride. Each air spring has an internal urethane jounce spring that absorbs bumps and shocks before they reach the cab. These jounces engage progressively—the more you load up, the stiffer they become—helping prevent bottoming out and reducing sway or bounce through corners. Even if your air pressure runs low, the internal jounce springs temporarily support the suspension so you can stay safely on the move.
Every load is different, so being able to adjust your suspension makes a big difference. The LoadLifter 5000 Ultimate lets you dial in air pressure anywhere from 5 psi to 100 psi for precise support. Inflate both sides equally for front-to-back leveling or adjust them independently to correct side-to-side lean from uneven loads. Manual inflation valves and air lines are included for simple setup, with optional compressor systems available if you want in-cab control later on.
These air springs are made with 2-ply, fabric-reinforced rubber that holds up under heavy use. Each one includes Air Lift’s exclusive upper and lower roll plates to guard against punctures and add load capacity. High-strength Zytel nylon endcaps are lighter and stronger than steel while resisting corrosion over time. With urethane internals that stay reliable in hot or cold conditions and a lifetime warranty backing it all up, this setup is designed for years of dependable suspension support.
Installing real suspension support doesn’t have to mean a trip to the shop. The LoadLifter 5000 Ultimate kit includes mounting brackets and hardware for straightforward installation using standard tools. Once mounted, just inflate through the manual valves—no specialized equipment required. It’s a solid upgrade that fits into a weekend project while giving your truck a major boost in capability and confidence under load.

Sorry to hear that, Fred. What is your specific year, make, and model? We may have a better option for you. And did you already get a return label to send this one back?

Glad to hear the install went smoothly! Thanks for the suggestion on the brake line/ABS brackets too. Definitely something that could make a good kit even better!

Product works great and helps level the truck during towing. I have noticed a difference in the amount of travel my back wheels have when offloading. But I knew that would be a sacrifice.

Happy to hear these are getting the job done! Your set up looks great, and man! What a beautiful picture. Blue, sunny skies, green grass, a cool breeze (I'd wager) perfect day to hitch up the trailer and get some work done!

Been great! I really don’t like the internal jounce stops though. When you are unloaded and running lower bag pressure, a dip or bump will hit the bump stops really hard and jar your passengers in the backseat. It’s almost too uncomfortable to ride in the backseat now. As for the loaded and high pressure performance it’s great! Great handling and no sag at all when towing.

Install looks fantastic Lloyd! Glad to hear they helped with the side to side movement. What kind of trailer are you going to be towing with the new set-up? Fun camper, work trailer?

That is great to hear, even with some modifications I am glad this is what you were wanting. That truck bed camper set up looks awesome. Do you have any big trips planned this year?

That’s a pretty clever spot for the air fittings, I’m definitely taking note for the future! Also, if you ever run into instructions where the images are hard to see, feel free to reach out. We’re happy to email you a clearer digital copy anytime!

Wow, Brian. Thanks so much for your in depth review and experience with installing the air bags. You gave some really solid tips and advice, especially the one about removing the tires. How's the ride now when you're off road?

What all did you end up having to do to the brackets to get them to fit, if you don't mind sharing?

Well after a year and several long trips I can say these were a great investment, took most of the seat out of the motor home and helped in windy conditions. I would highly recommend them to anyone!
