When the bed or trailer is packed heavy, sag and sway can make the ride unstable. The LoadLifter 5000 Ultimate air springs add up to 5,000 lbs of load-leveling capacity, keeping your vehicle level from front to back and side to side. By reducing the strain on your rear suspension, they help maintain safe headlight aim and improve steering and braking response when towing or hauling serious weight.
Every bump and dip in the road doesn’t have to rattle the cab. Each air spring has a closed-cell urethane jounce spring inside that engages progressively as loads increase, absorbing shocks and helping prevent bottoming out. Even with low or zero air pressure, the internal jounces provide temporary support so you can still carry a load until you refill the system. The urethane material compresses smoothly for a stable, comfortable ride compared to harsh rubber bumpers.
Every trip is different—sometimes you’re towing heavy, other times you’re running light. With these springs you can fine-tune support anywhere between 5 psi and 100 psi using the included manual inflation valves and air lines. Inflate equally for front-to-back leveling or separately for side-to-side adjustments when carrying uneven loads. The system works with optional compressor setups for in-cab control if you want easier adjustments down the road.
These air springs are ready for real work. Each one is made from 2-ply, fabric-reinforced rubber with high-strength Zytel nylon endcaps that are lighter, stronger, and more corrosion resistant than steel. Air Lift’s exclusive roll plates guard against damage from moving parts under the vehicle while extending spring life and increasing load capacity. All mounting brackets and hardware are included for a solid install that’s built to last through years of towing and hauling duty.

Instructor Today we're gonna be taking a look at Air Lifts line of LoadLifter 5,000 Ultimate Air Helper Springs with internal jounce bumpers. These bags are specifically designed for three quarter and one ton trucks and motor homes, you're big heavy dogs here. These bags are a custom fit for your particular truck so you want to use our fit guide to ensure you get the appropriate hardware and brackets to install them. To show off our airbags, we're going to add about a thousand pounds of water weight to the back of our truck. We're working with a Chevy Silverado 3,500 today, but the principles are the same regardless of your vehicle. Having your vehicle loaded down like this, bringing the back down and the front up, changes the geometry of your suspension, and it also changes the way weight is loaded onto your front brakes.
So this causes poor handling, as well as poor braking performance. By adding air bags into the back of our vehicle, we can raise the back of our vehicle back up, and that's also gonna help restore the suspension closer to that factory ride height as well. That's gonna give us better contact on the road with our tires so they don't wear excessively fast, it's gonna increase our handling because we're going to have better contact to the road, and with it level back up here at the front again, our weight's gonna properly transition onto the front brakes restoring a lot of that loss breaking performance. Another added benefit is by bringing the back of our vehicle back up, we're picking our headlights that we're pointed up towards the sky and bringing them back down on the road, so we we're able to see better at night as well. And here we can see our airbags installed.
They're going to sit between the axle and the frame of your vehicle, and they'll provide up to 5,000 pounds of leveling support. Now this doesn't increase the amount of weight that you can carry with your vehicle, that's just how much these can help to support and lift your vehicle back up to restore that lost ride height that you had from being weighed down. Inside of our airbag here, there's a jounce bumper, and what that does for us is in the event that we've got it so loaded up and we hit a really big bump, and our axle moves up. If it we're to go up so far, it could contact the internal jounce bumper and that's going to prevent any metal on metal contact, And it's also going to save our bag from any potential damage. This is mostly for when you get really heavily loaded, really pushing it, getting close to the maximum load limit of your vehicle, that jounce bumper can really come in handy when you're maybe doing some good speeds and you hit a pretty big pothole or something like that, that could save you and your vehicle from any issues.
To further increase the structural integrity of our bag, there's roll plates on the top and bottom, so as our vehicle goes to sway to the left or to the right, when we're making invasive maneuvers or just regular turns, the bag as it wants to lean to one side of the other, from that sway can contact on the roll plate here, and that'll provide it with additional support to ensure that our bags stay in place doing their job. The double convoluted design will help increase the structural integrity of our bag. It gives it a higher burst pressure by displacing the air as necessary as it moves up and down. And to further ensure the durability of our gags, they're constructed of a two ply fabric reinforced rubber, and they're very durable here. They have a increased size on that internal jounce bumper as well.
The urethane bumper is a little bit taller so it'll contact a little bit sooner, and that's really nice if you maybe haven't adjusted your air pressure quite yet, either. Maybe you've loaded it up and it's still a little bit lower pressure, that jounce bumper is always gonna be in there to provide contact, and then if you find that, hey, you're hitting that jounce bumper, it's a little stiff, you can up the air pressure a little bit to help bring that away and get the best ride quality, as well as the best support. You also receive a heat shield in your kit, this is gonna further protect your bag from any excessively hot sources, such as your exhaust here. You'll receive clamps with it and everything, so that makes it nice and easy to get that installed, and it's very easy to position it and however you need to for your particular exhaust system. So it's nice, even if you upgrade your exhaust system, you'll still be able to use something like this. Included with your kit, you're gonna receive airlines and all the hardware you need to get it installed. You'll receive two air fittings so that way you can inflate each bag independently from one another. This is nice if you're trying to correct any uneven loads, but really in most cases, when you're loading down your truck, you typically want to load both of your bags the same to just bring that support back up and level your truck back out, and in those instances, the easiest way to do it will be to install a compressor on your vehicle. On this vehicle, we've installed Air Lift's WirelessONE compressor, and this is one of the easiest compressors to install. It's completely wireless and you can operate it with your phone, so you don't have to worry about losing any kind of device when you're trying to inflate it. And you don't even have to get out of your truck to inflate it. So you could pull up to a place and have somebody drop a pallet in the back of your truck, adjust the pressure on your phone and take off. The operating range of our bags is between five and a hundred PSI. Five pounds is when we're just normal driving around, completely unloaded. It is important to have five pounds in there because as your suspension moves up and down, it can create a small vacuum in there if you don't have any pressure, so we just keep that five pounds in there. And then for your heaviest loads, we can go up to all the way to a hundred pounds to provide that support. Just wanna keep in mind that up at those higher pressures it does get pretty stiff, and in most cases, about 40 to 50 pounds is gonna probably be sufficient. And that completes our look at Air Lift's line of their LoadLifter 5,000 Ultimate Air Helper Springs with internal jounce bumpers..

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?
