A heavy trailer or full bed can make your truck squat and throw off braking and steering. The Air Lift LoadLifter 5000 Ultimate air springs add up to 5,000 lbs of load-leveling capacity to keep your ride level and stable. Whether you’re towing a camper or hauling equipment, the adjustable air bags distribute weight across all four wheels for better control and even tire wear. You’ll keep your headlights aimed properly, your handling steady, and your confidence high even with serious weight on the hitch.

Rough roads and uneven loads can make any trip uncomfortable. Inside each air spring is a closed-cell urethane jounce spring that helps absorb bumps and shock at lower air pressures. These jounces engage progressively—the more you load them, the stiffer they get—so you get a smoother, less jerky ride when towing or hauling. If air pressure drops, they even act as a temporary fail-safe to protect your suspension until you can reinflate the bags.

Every load is different, so being able to fine-tune your setup matters. With manual inflation valves and included air lines, you can adjust each bag independently between 5 psi and 100 psi for side-to-side or front-to-back leveling. Add more air for heavy loads or drop it down when empty for a softer ride. A compressor system with in-cab gauges or wireless controls can be added later for easy monitoring and adjustment on the go.
When you’re relying on suspension support day after day, durability counts. Each LoadLifter 5000 Ultimate uses 2-ply, fabric-reinforced rubber air springs with high-strength Zytel nylon endcaps that are lighter and more corrosion resistant than steel. Exclusive roll plates guard against damage from moving parts under the truck while increasing spring capacity. With quality brackets, hardware, and urethane jounces that need no maintenance, this setup is built to handle real work through heat, cold, and long miles without leaking or wearing out.
Installing suspension upgrades shouldn’t be complicated. The system includes mounting brackets, hardware, manual inflation valves, and air lines so you can bolt everything in with standard tools. With a clean layout and easy-to-reach valve mounting on the bumper or another accessible spot, you can be up and running quickly. Once installed, just add air and hit the road knowing your load is level and your suspension is supported for whatever the day brings.

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.

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!

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?

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

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?

Wow that's great, Slater :) Did you get the travel trailer a year ago too, or have you had it for a while? Any recommended destinations for your viewers at home?
