When you’ve got a heavy trailer or bed full of gear, the rear end can sag and throw off your steering and braking. The Air Lift LoadLifter 5000 Ultimate air springs add up to 5,000 lbs of load-leveling capacity so your truck stays level and stable under pressure. They balance the load across all four wheels, helping maintain safe headlight aim and confident handling even when you’re hauling serious weight.
Rough roads and uneven loads don’t have to mean bouncing down the highway. Each air spring has a closed-cell urethane jounce spring inside that absorbs bumps, resists bottoming out, and smooths out the ride. When air pressure is low, the jounce spring still provides support so you can keep moving until you can add air. The more weight you carry, the stiffer the jounce gets for progressive control that keeps your setup comfortable and steady.
Different loads call for different setups. With adjustable air pressure from 5 psi to 100 psi, you can fine-tune each bag to match what you’re carrying. Inflate both equally to level front-to-back or adjust them individually for side-to-side balance when your load is off-center. Manual inflation valves are included for easy access, and if you want more convenience, compressor systems are available separately for in-cab or wireless control.
Air Lift built these springs to last through years of towing and hauling. The 2-ply, fabric-reinforced rubber air bags use high-strength Zytel nylon endcaps that won’t rust or corrode like steel. Exclusive roll plates protect each spring from sharp edges and moving parts under the truck while increasing their effective load area for a smoother ride at lower pressures. All mounting brackets, hardware, air lines, and inflation valves are included for a solid install backed by a lifetime warranty and a 60-day satisfaction guarantee.
This system includes everything needed to mount directly onto your rear axle with simple hand tools—no complicated mods required. Once installed, just add air through the valves and go. Whether you’re towing a camper a few times a year or hauling bed loads every day, these Air Lift LoadLifter 5000 Ultimate springs give your suspension the support it needs without giving up ride comfort when empty.

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?

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?

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!
