Heavy loads can cause sag, sway, and uneven handling. The LoadLifter 5000 air helper springs provide up to 5,000 lbs of load-leveling support to keep your vehicle level and stable under pressure. By distributing weight across all four wheels, they reduce strain on your factory suspension and improve steering, braking, and headlight aim when towing or hauling serious weight.
Every load is different, so being able to tune your suspension matters. With manual inflation valves and included air lines, you can adjust each spring independently from 5 psi to 100 psi. Add more air for towing or heavy cargo to keep things level, or drop it down when unloaded for a smoother ride. Independent inflation also lets you correct side-to-side imbalance when carrying uneven loads.
This system is made for long-term hauling. Each air spring uses 2-ply, fabric-reinforced rubber with endcaps built from high-strength Zytel nylon that’s lighter, stronger, and more corrosion resistant than steel. Air Lift’s exclusive upper and lower roll plates protect the springs from damage while increasing their load capacity. It’s a setup designed to handle rough use without leaks or failure.
The LoadLifter 5000 kit includes mounting brackets, hardware, air lines, and manual inflation valves for straightforward installation. Mount the springs, connect the airlines, and inflate—no complicated setup required. Valves can be placed on the bumper for easy access, and if you want more convenience later, a compressor system with in-cab gauges can be added separately for automatic pressure control.

Hi, everybody, Andy here with etrailer.com. Let's take a real quick look together at these Air Lift LoadLifter 5000 Air Helper Springs for your rear axle. Now these have been designed to fit your 2019 and newer Mercedes-Benz Sprinter 2500 with two-wheel drive and a 144-inch wheelbase. On custom fit parts such as this kit, I do recommend taking advantage of our Vehicle Fit Guide here at etrailer.com. Simply input the year, make, and model of your vehicle, and our Fit Guide will confirm if this will work for you or if we have something comparable that will work for you. Now, if you're looking for this kit for the same vehicle with a longer wheelbase, we do have that option available for you as well.
Again, the Fit Guide will point you in the right direction. So with this kit, you are going to get a safer ride while at the same time, protecting your vehicle from the strain that comes with hauling heavier loads. As you know, carrying heavy cargo puts tremendous stress on your vehicle. Your brakes erode faster, your tires wear unevenly, and the handling is going to suffer severely. When towing, you might also experience excessive sway, and bottoming out, and even improper and unsafe headlight aim.
So, by pairing your existing suspension with these LoadLifter 5000s, you can seriously beef up your suspension, you can ensure an equal load distribution, and you can also give your vehicle the support that it's going to desperately need. These air helper springs are gonna give you up to 5,000 pounds of load leveling capacity. It's gonna help distribute the weight of your payload to all four of your wheels. So, as a result, the stress on your OEM suspension is going to be, obviously, significantly reduced. Now, taking a slightly closer look at this system, these airbags are made here in the USA of high-quality, two-ply, fabric-reinforced rubber.
Most airbags lose air at the ends, where the bag is enclosed with the steel cap because that steel can rust and corrode over time, creating small holes. But the end caps on our springs here, and you can't see them because I do kind of have them loosely assembled with the roll plates and the custom fit brackets, just to kind of give you an idea of what these are gonna look like when they're installed. But on these airbags, the end caps are fashioned from corrosion-proof Zytel nylon. That's a material that's both stronger and lighter than steel, so that's going to ensure that the bags won't lose air. Also, these springs do come with Air Lift's exclusive roll plates, which both protect your air springs and beef up the load capacity of the springs.
These springs are adjustable from five to 100 PSI, giving you that precise support, and they can be inflated independently of one another for front, rear, or side-to-side leveling. Now, everything that you see here laid out on my table is going to be included in this kit. It's going to include the custom mounting brackets and then I mentioned the roll plates, the manual inflation valves, air line, the hardware that you're going to need to get this into place, along with this set of instructions to guide you through that installation process. The manual inflation valves are typically mounted on the bumper for easy access. And you can get compressor systems with end cap gauges that can be added to monitor and automatically adjust the air pressure. Those items, we do sell separately on our website, but you can find them under the Related Products section or Related Products tab on this product page. Now, again, the load leveling capacity of this kit is 5,000 pounds, but it is important to remember that these air springs do not actually increase the weight carrying capacity of your vehicle. So you do wanna make sure that you don't exceed what the manufacturer says is your weight limit for your vehicle. Well, I think that's gonna wrap up our look today. I do hope that our time together has been helpful for you. Again, my name is Andy, thank you for joining me.

Things are working well so far. I tow and haul during the spring,summer and fall. The most air I put in the bags was 50 PSI. The air still holds pretty good towing.Time will tell if the bags hold up as the bags age.

Nice job running the Schrader valves through the license plate, that's how I'd do it! '

Definitely should get the job done! Thank you for including the photos - it's always nice to see what things look like in real life situations. Let us know what you think once you've been able to tow, we'd love to know! :)

Excellent!!! This kit gave me a lot more stability and better ride while towing our 24’ camper. Highly recommend to anyone towing with a Tacoma

Glad to hear they are working well for you and they weren't too difficult for your mechanic to get installed, Matthew! Sounds like you have your Taco pretty tricked out! Are you doing an overlanding type thing?

Glad we could make it go smoothly for you, Mary! Speaking of smoothly, had you had a chance to try them out yet?

The Air Lift is working GREAT a year later. We just hauled a Generac 705 miles up north and brought a load of big rocks back for a guy that wanted to build a waterfall for his coy fish and the Air lift system was able to handle the weight just fine and rode great. Every one comments about how smooth the truck rides. The Air Lift system has handled everything we have asked it it to and has been trouble free. These will go on every truck I won in the future.

Besides the time it took, I am glad you were able to get these installed and notice a difference right away! They look nice installed. Are you towing anything other than your dump trailer?

Glad to hear you are still liking them, Zach! Are the picture you sent in before or after the bags were installed? If it's after, I think you could actually go with a little higher pressure to really level out!

So far, After a year of use, these air bag helpers I installed on our 21 Ram 1500 Laramie 4x4 Crew Cab are working just fine. Id recommend them in a heartbeat.

Sounds like the perfect upgrade for you, Randy! How often are you towing your 5th wheel?

Wow, I love this review because you really show how versatile these air helper springs can be! Towing, hauling, off-roading...what else is there? This is great!

Airlift Bags have performed well, compressor does adjust more at low pressure 10 psi I assume for air temp change, I have checked for leaks multiple time and none found. 6500 towing miles at 80 psi with little auto adjusting pressure and no issues.

Inflation valves tend to loosen. Must be checked regularly. Suggest some type of lock washers be supplied. The only way I found to improve the rear seat ride is to decrease tire pressure. I only do this when expecting passengers so I don’t wear the tires excessively.
Do you have a question about this Vehicle Suspension?

Would love to know your thoughts on them once you're able to try them out with the travel trailer, too! Thanks for sharing the different things you've used them with. Sounds like they are just the ticket for your scenario :)
