When your trailer, camper, or bed load starts weighing down the rear, the LoadLifter 5000 Ultimate air springs step in to keep your ride level and steady. With up to 5,000 lbs of load-leveling capacity, they take strain off your rear suspension so braking and steering stay predictable even when the load gets heavy. Adjustable air pressure from 5 to 100 psi lets you dial in just the right support to keep your truck sitting level for safer handling and correct headlight aim.

Every bump or dip on the road doesn’t have to knock your cargo or your confidence around. Each LoadLifter 5000 Ultimate air spring has a closed-cell urethane jounce spring inside that kicks in when needed to absorb shocks and reduce sway. The jounce engages progressively—the more weight you add, the stiffer it gets—so the ride feels smooth instead of harsh. Even if your air springs lose pressure, those internal jounces help carry the load temporarily to protect your suspension until you can make adjustments.

These air springs are built to handle real work and long miles. The 2-ply, fabric-reinforced rubber bags are protected by Air Lift’s exclusive upper and lower roll plates that guard against damage from moving parts under the vehicle. High-strength Zytel nylon endcaps are lighter, stronger, and more corrosion-resistant than steel, so you don’t have to worry about rust eating away at your suspension support over time. It’s a setup made to last through tough jobs and rough roads.
Installing serious suspension support doesn’t have to be complicated. The kit comes with mounting brackets, hardware, manual inflation valves, and air lines. Just mount the springs, hook up the valves—typically on your bumper for easy access—and inflate. If you want hands-free control later on, an optional compressor system with in-cab gauges can be added separately. It’s a straightforward install that fits right into a weekend project for anyone who likes to handle their own upgrades.

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?

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?

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?

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!
