Heavy trailers and loaded beds can make the rear of your truck sag, throwing off braking and steering. The LoadLifter 5000 Ultimate air helper springs add up to 5,000 lbs of load-leveling capacity to keep your vehicle level and stable. They pair with your existing suspension to distribute weight evenly and help maintain safe headlight aim. With air pressure adjustable from 5 psi to 100 psi, you can fine-tune support for towing or hauling without overstressing your factory suspension.
Rough roads and changing loads can make any suspension bounce or bottom out. Inside each LoadLifter air spring is a closed-cell urethane jounce spring that absorbs bumps and adds stability when your air pressure is low. These jounces engage progressively—the more you load them, the stiffer they become—so you get a smoother ride with less sway and better cornering control. They also act as a fail-safe, temporarily supporting your suspension if pressure is lost.
Air springs only work as long as they hold air, so durability matters. Each LoadLifter 5000 Ultimate uses 2-ply, fabric-reinforced rubber with exclusive upper and lower roll plates that protect against damage and extend life. High-strength Zytel nylon endcaps are lighter, stronger, and more corrosion resistant than steel, keeping the system leak-free through years of use in any weather.
Setting up your air springs doesn’t require a shop visit. The LoadLifter 5000 Ultimate includes mounting brackets, hardware, air lines, and manual inflation valves so you can get up and running with basic tools. The valves can be mounted on the bumper for quick access and individual adjustment side to side for uneven loads. If you want more control from the driver’s seat, a compressor system with in-cab gauges or wireless control can be added later.

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!
