When towing or hauling heavy gear, rear-end sag can throw off your handling and braking. The LoadLifter 5000 Ultimate air helper springs add up to 5,000 lbs of load-leveling capacity to keep your truck level from front to back. The setup helps maintain safe headlight aim and steering response while reducing strain on your factory suspension. With air pressure adjustable from 5 psi to 100 psi, you can fine-tune support for whatever you’re carrying.
Rough roads and uneven loads don’t have to mean a rough ride. Each air spring has a closed-cell urethane jounce spring inside that steps in when air pressure isn’t enough to handle the bumps. The jounce spring engages progressively—the more weight you add, the stiffer it gets—so your suspension stays smooth and stable instead of bottoming out. Even if air pressure drops, the jounces temporarily support your suspension so you can keep moving without damage.
Durability matters when you depend on your suspension every day. These 2-ply, fabric-reinforced rubber air springs are built with high-strength Zytel nylon endcaps that are lighter, stronger, and more corrosion resistant than steel. Air Lift’s exclusive upper and lower roll plates protect the bags from moving parts under your vehicle, adding strength and extending spring life. Urethane internal jounces require no maintenance and hold up through heat or cold for consistent performance season after season.
Installing these springs is straightforward with included mounting brackets, hardware, air lines, and manual inflation valves. Once mounted, just pump up each side through the valves—typically placed on the bumper—for easy access. You can inflate both equally for front-to-back leveling or separately for side-to-side balance when loads aren’t even. If you want more control, compressor systems with in-cab gauges or wireless operation (sold separately) make it easy to monitor and adjust pressure while you drive.

After about a year the Air Lifts are doing just great! The 5th wheel trailer that loads the rear axle now rides level and is exactly why I purchased the Air Lifts. Easy to add or reduce air pressure as needed. Thanks for asking.

This product really answered all the complications I was having with pulling my camper, I keep 10psi in them when I’m not pulling anything and it has improved the overall handling of my truck, this is an awesome product and I highly recommend it

I double checked with the manufacturer and it seems that this kit will only fit a 2 wheel drive truck

Great, these Air Bags were a great addition to my towing setup. Much smoother ride when towing. I would however add the compressor so you can easily adjust while driving

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?

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?
