Haul and tow with confidence! Air Lift LoadLifter 5000 air springs level your ride for better braking, handling, and comfort while reducing strain on your suspension. With a 5,000-lb capacity, they keep your vehicle stable and ready for heavy loads.
When you're carrying heavy payloads or towing large trailers, keeping your vehicle level can be a challenge. The Air Lift LoadLifter 5000 air springs provide up to 5,000 lbs of load-leveling support for your rear suspension, reducing sag and improving both braking and steering. By distributing the load evenly, these air springs ensure you maintain a safe and smooth ride, no matter the cargo.
Hauling uneven loads can put significant strain on your vehicle's suspension. With the LoadLifter 5000, you can manually adjust the air pressure from 5 psi to 100 psi for optimal load distribution. Inflate each spring independently to meet specific leveling needs, whether front-to-rear or side-to-side. This adjustability helps diminish sway and road shock, offering a stable towing experience.
Protect your investment and enhance safety with the LoadLifter 5000's robust design. Constructed from high-quality, two-ply, fabric-reinforced rubber, these air bags are paired with endcaps made from high-strength Zytel nylon, which resists corrosion and damage better than steel. This thoughtful construction safeguards your air springs, extending their lifespan and ensuring consistent performance.
For those who want ease of use, consider adding an air compressor system, like the Air Lift WirelessAIR. This system allows you to adjust the air pressure directly from your vehicle's cab, providing flexibility on the go. Monitor and personalize your suspension settings effortlessly, ensuring your vehicle remains level and ready to tackle any terrain or load.
Carrying heavy loads can wreak havoc on your vehicle's original suspension, leading to accelerated wear and costly repairs. By using the LoadLifter 5000, you can significantly decrease the stress placed on your OEM suspension components. Not only does this protect against uneven tire wear and unsafe headlight aim, but it also contributes to the overall longevity of your vehicle's systems.
Built to last, your Air Lift air helper springs are proudly made in the USA. Backed with a lifetime warranty, you can trust its durability and performance for every mile of your journey. Whether you're embarking on your first or fiftieth road trip, rest easy knowing your air springs are crafted with precision and care.

Hi everybody. Andy here with etrailer. Let's take a quick look at this Air Lift LoadLifter 5,000 Air Helper Spring Kit for your rear axle. So this has been designed to fit your 2025 to current Toyota 4Runner and on custom fit parts such as this kit, I do recommend taking advantage of our Vehicle Fit Guide here at etrailer. Just pop in 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 if you're doing a lot of towing or hauling heavy stuff, this kit is a helper system for your 4Runner's OEM rear suspension.
This does use airbags, actual rubber air springs that are going to sit between your frame and the rear axle. So when you add weight to the back of your vehicle, things naturally start to sag and that sag can make the steering feel light, it can change how your headlights are aimed and generally make your 4Runner feel less stable. This kit is going to fix that by letting you add air to the bags whenever you're carrying a heavy load. So more air equals more support. And the cool thing is that these are fully adjustable.
If you're towing a trailer, you pump the air bags up and when you're not carrying anything, you run them at a low pressure and then the 4Runner is going to ride normally. The adjustable air pressure is from five to 100 PSI. So this kit is designed to give you up to 5,000 pounds of load leveling support. It doesn't actually increase your 4Runner's official payload or tow rating, but it does help the rear suspension handle weight more confidently. People who tow regularly notice an improvement in stability, braking, and even tire wear because the vehicle stays level instead of sagging.
So as you can see here, I do kind of have these just loosely assembled here. I wanted to give you an idea of what the springs we inchesre gonna look like with the roll plates and the brackets put together, how it's going to look when it's mounted to your 4Runner. But this kit does include everything that you're going to need, the springs, the brackets, the air line, the fittings and everything, everything that you're going to need. Everything's designed to bolt on without drilling on your 4Runner. Once installed, you just need to add or release air depending on what your load looks like that day.
Now something else that I want to mention just kind of for your consideration, if you want ease of use, you ought to consider adding an air compressor system like the one that I have listed there on your page, on your screen rather. This is the Air Lift Wireless Air and this system allows you to adjust the air pressure directly from your 4Runners cab. It's gonna give you flexibility on the go. You're gonna be able to monitor and personalize your suspension settings effortlessly. That's going to ensure that your 4Runner remains level and ready to tackle any terrain. What's nice about this as well is maybe you're doing, you're going over rough terrain or you're rock crawling in your 4Runner. This is going to allow you to also adjust the pressure in your tires. It comes with a line in a chuck there where you can blow things up like inflatables or adjust the tire pressure on your 4Runner. So you've got a lot more capability with this particular system. So if you're interested in taking a look at that, I do have that part number for you on your screen. Take that part number, pop it in the search field of our website. That will take you to that kit and you could add that to your order if you so desire. One other thing I wanna mention, if you want help with installation, we do have you covered. If you take a look at this product page underneath the photo section, we have a link to our Installer Locator. Click that link, 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. That's gonna conclude our look today. I do hope that it 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! '

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?

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.

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.

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 :)
