When you’re towing a trailer or hauling heavy gear, the rear of your truck shouldn’t drag down. The LoadLifter 5000 Ultimate air helper springs add up to 5,000 lbs of load-leveling capacity to keep your ride level and balanced. They reduce strain on your suspension, improve braking and steering response, and help maintain proper headlight aim even under heavy loads. Adjustable air pressure from 5 psi to 100 psi lets you fine-tune the support for any situation.
Rough roads or uneven loads can make your truck bounce and sway. Each LoadLifter 5000 Ultimate air spring has a closed-cell urethane jounce spring inside that engages progressively as weight increases. This design absorbs road shock, smooths out bumps, and keeps cornering controlled without a harsh ride. If the air pressure drops, the internal jounce acts as a backup to temporarily support your load until you can refill the bags.
These springs are built for serious work with 2-ply, fabric-reinforced rubber air bags and corrosion-proof Zytel nylon endcaps that are lighter and stronger than steel. Air Lift’s exclusive upper and lower roll plates protect each bag from moving parts under the vehicle while boosting load capacity. The urethane jounce springs inside require no maintenance and perform reliably in hot or cold temperatures, ensuring years of dependable service.
Getting your truck leveled is straightforward. The kit includes manual inflation valves and air lines that mount conveniently on the bumper or another accessible spot. You can inflate both sides equally or adjust them independently for side-to-side leveling when carrying off-center loads. If you want in-cab control, the system is ready for an optional compressor setup that lets you monitor and adjust air pressure on the fly.
Designed for heavy-duty applications like 3/4-ton and 1-ton pickups, motor homes, and commercial trucks, this hybrid system combines the adjustability of air springs with the reliability of jounce-style springs. With quality hardware, protective roll plates, and a lifetime warranty with a 60-day satisfaction guarantee, it’s built to handle the toughest towing and hauling tasks trip after trip.

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?

That’s a pretty clever spot for the air fittings, I’m definitely taking note for the future! Also, if you ever run into instructions where the images are hard to see, feel free to reach out. We’re happy to email you a clearer digital copy anytime!

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?
Do you have a question about this Vehicle Suspension?

Im amazed that they havent popped. I definitely put these air bad through more torture than they were intended for. It does seem like they dont lift as well after a few years.
