Hauling a big trailer or a bed full of gear can cause serious sag and shaky handling. The Air Lift LoadLifter 5000 Ultimate air springs add up to 5,000 lbs of rear axle support to keep your truck level and steady when it’s working hard. With the ride height corrected, steering and braking stay predictable, and your headlights stay aimed where they should be.
A heavy load on rough pavement can make your suspension bottom out and toss you around. The built-in urethane jounce springs engage even at low air pressure to absorb bumps before they reach the cab. These air springs also deliver progressive support—the more weight you carry, the firmer they get—helping control sway and bounce so the truck feels planted and comfortable no matter the road surface.
Every load is different, so your suspension should adapt. The LoadLifter 5000 Ultimate lets you fine-tune firmness with air pressure between 5 psi and 100 psi. Add air when towing or hauling to level things out, then drop back down when empty for a smoother ride. Manual inflation valves mount on the bumper, and you can pair them with an optional WirelessAIR system for quick adjustments straight from your phone.
When you hit uneven ground or need full articulation, losing travel isn’t an option. The included spring cradles keep the air bags properly positioned while allowing complete suspension droop. That means your setup keeps traction off-road without binding or limiting flex, all while maintaining stable support under load.
Air systems are only as reliable as their seals and materials. The LoadLifter 5000 Ultimate uses corrosion-proof Zytel nylon endcaps that are lighter yet stronger than steel, resisting rust and air leaks that can sideline lesser kits. It’s durable hardware with a lifetime warranty and a 60-day satisfaction guarantee for long-term confidence wherever you haul.

Hi, everybody. Andy here with etrailer. Let's take a quick look at this Air Lift LoadLifter 5,000 Ultimate Rear Axle Air Helper Springs with Internal Jounce Bumpers. Now this kit has been designed to fit your 2021 to 2025 RAM 1500 and on custom fit parts such as this kit, I do recommend taking advantage of our Vehicle Fit Guide here at etrailer. Pop into year, make and model of your vehicle, answer any other questions that it might have for you. And our Fit Guide will confirm if this kit will work for you or if we have something comparable that will work for you.
So this is an air suspension upgrade kit that's custom fit for your truck. So it's gonna bolt right into existing mounting points. No complicated modifications are gonna be needed, and what this really does is help your truck handle weight better. So if you're towing a trailer or carrying a heavy load in the bed, this system is gonna be able to support up to 5,000 pounds of load leveling. That's gonna keep your truck sitting level instead of sagging in the back, which is gonna make a big difference in safety and control.
This is also going to help improve your ride quality. As I mentioned, these bags have internal jounce bumpers that are gonna help absorb bumps and rough roads, so you're not gonna be feeling every dip or dealing with that harsh bottoming out feeling. And when you're towing, the system's gonna stiffen progressively under load. So that's gonna help with braking, steering and overall stability. Durability-wise, this system is designed to last.
The end caps of these airbags are made from corrosion-resistant nylon material, so you're not gonna have to worry about rust or air leaks over time. One of the best parts with this kit is adjustability. You're gonna be able to fine tune the air pressure anywhere from five to 100 PSI. So if you're driving empty, you can keep it soft and comfortable. And then when you're loaded up, just add air for more support.
And if you ever take your truck off-road, this is still a solid option because this kit does come with the spring cradles that are gonna let the suspension fully extend without limiting travel. So you're gonna be able to keep traction and flexibility on uneven terrain. And then if you wanna make it even easier, you can add a wireless system that's going to add, that's gonna let you adjust the air pressure right from your phone instead of messing with manual controls. And we do have those kits available here at etrailer, it's gonna come with the compressor and everything that you need to adjust the air pressure from either inside of the cab of your truck or from your phone. This does include everything that you see here on my table. You're gonna get the airline, the air fittings, the hardware, the brackets. I kind of have it loosely set up here as to how that's going to mount on your truck. Instructions are also included to guide you through the installation process. Speaking of installation, if you don't wanna really deal with that installation yourself, we do have you covered on that front. On this product page underneath the Photo section, we have a link that will take you to our Installer Locator, answer the questions that it has for you, and that locator will find an installer in your area that etrailer has partnered with to do the installation for you. Well, again, my name is Andy. Thank you for joining me.

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 you are keeping air in there when not in use Bradley! Are you always going to the same place on those 700 mile trips?

This product has been holding up in the Midwest climate. We have used it several times for hauling our camper. The bags are still in great shape.
