Heavy trailers, campers, or bed loads can make the rear of your vehicle sag and throw off braking and steering. The LoadLifter 5000 air springs add up to 5,000 lbs of load-leveling support to keep your ride height normal and your handling safe. By distributing the weight across all four wheels, it reduces strain on your factory suspension and keeps your headlights properly aimed. Whether you’re towing or hauling, you get a level stance and stable control under load.
Every haul is different, so it helps to have control over how your suspension responds. The LoadLifter 5000 lets you fine-tune air pressure between 5 psi and 100 psi for the right amount of support. Inflate each spring separately to even out side-to-side loads or keep things level front to rear. Manual inflation valves are included, and they mount easily on the bumper for quick access. Add air for heavy towing days or drop it down for a smooth everyday ride.
Rough roads and heavy loads can beat up factory suspension parts fast. These air springs are built with two-ply, fabric-reinforced rubber and fitted with exclusive upper and lower roll plates that protect the bags while boosting their load capacity. The endcaps are made of high-strength Zytel nylon that’s lighter, stronger, and more corrosion resistant than steel, so you can count on them to stay sealed tight mile after mile.
Installing real suspension support doesn’t have to be complicated. The kit comes with mounting brackets, hardware, air lines, and manual inflation valves—everything you need to get set up. Just bolt the springs in place, connect the air lines, inflate them, and you’re ready to roll. You can even add a compressor and in-cab gauge system later for automatic or on-the-fly adjustments if you want even more convenience.

Hi, everybody, Andy here with etrailer.com. Let's take a look at this Air Lift LoadLifter 5000 Air Helper Spring Kit for your rear axle. Now, this kit has been designed to fit your 2019 and newer Mercedes-Benz Sprinter 2500 with the four-wheel drive. And on custom fit parts, 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 kit will work for you or if we have something comparable that will work for you. So with this kit, you're going to get a safer ride, while at the same time protecting your Sprinter from the strain that comes from hauling heavy loads.
Now, as you know, carrying heavy cargo can put tremendous stress on your Sprinter, your brakes erode faster, your tires wear unevenly, and handling will suffer very severely. Now, when towing, you might experience excessive sway, bottoming out, or even improper or unsafe headlight aim. So by pairing your existing suspension with this LoadLifter 5000 Kit, you can seriously beef up your suspension and ensure equal load distribution, and give your Sprinter the support that it desperately needs when hauling heavy loads. These air helper springs are going to give you up to 5,000 pounds of load-leveling capacity, and it's going to distribute the weight of your payload to all four wheels. And as a result, the stress on your OEM suspension is going to be significantly reduced.
Now, taking a slightly closer look here, these air bags are made here in the USA of high-quality, two-ply, fabric-reinforced rubber. Most air bags lose air at the ends where the air bag is enclosed with the steel cap, because the steel can rust and corrode over time, creating small holes. That's why some of those other air bags will lose air. But the end caps on these Air Lift air bags are fashioned from corrosion-proof Zytel nylon. That's a material that is both stronger and lighter than steel, ensuring that these air bags will not lose air over time.
Also, these springs come with Air Lift's exclusive roll plates that you see here. And as you can see, I do have them kind of loosely assembled, just to kinda give you an idea of what the installed product is going to look like on your vehicle. But here, we do have our roll plates here. They're gonna protect both your air springs and beef up the load capacity of the springs. The springs are adjustable from 5 to 100 psi, giving you precise support.
They can be inflated independently of one another for front-to-rear or side-to-side leveling. Everything that you see laid out here on my table is going to be included in this kit. It includes the custom mounting brackets, again, that I have kind of loosely assembled to the springs, all the hardware that you're going to need to install it, some of the hardware I'm using here to hold the brackets onto the spacers and to the springs. You're gonna get manual inflation valves, the air line is included. The manual valves are typically gonna be mounted on the bumper for easy access. And this also includes instructions to guide you through the installation process. Now, you can also get compressor systems with in-cab gauges that can be added to monitor and automatically adjust the air pressure. Those items we do sell separately on our website here at etrailer.com, but you can find them under the related products section on this product page. Now, the load-leveling capacity is 5,000 pounds, as I mentioned. But it's important to note that these air helper springs do not actually increase your Sprinter's weight carrying capacity. So you wanna make sure that you're not exceeding your manufacturer's recommended weight limit. And these do have a lifetime warranty from Air Lift. Well, I think that's gonna wrap up our look today. I do hope that our brief time together was 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.

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 :)
