Review of the Air Lift LoadLifter 7500 XL Rear Air Helper Springs


Hi there heavy haulers, today we're going to be taking a look at Air Lift's LoadLifter XL series airbags. And these are the heavy-duty series airbags that are going to offer more support than their 5000 series bags. We're showing off a set on our F-350 Super Duty today, but you'll want to make sure that you use our fit guide to ensure that you get the correct bags for your particular truck.Before we install our airbags, we're going to go ahead and hit our test course, just to get a baseline of how our truck feels. We're going to start on our bumps course, and it's going to be an uneven bump section first, and this is going to simulate like hitting a pothole. And we can feel it rock here. It's not too bad.

Our suspension actually feels pretty stiff on this truck already, but I do suspect that with the airbags back there, it can help soften it out just a little bit. Especially if you keep the air pressure a little bit lower. As you increase that pressure, it does make it a little bit stiffer. And when you get towards the upper echelon of what that's rated for, it does get very stiff.Next we're going to be going into the even bump section. And this is going to simulate going over a speed bump, or maybe pulling in and out of your driveway.

And when we hit the bumps here, we can feel in the back, it does still feel pretty stiff. We got a little bit of bounce up and down, but it's not too bad. I do feel like our airbags are going to help stiffen that out. And then lastly, here, we're going to be going into our slalom section, where we're going to simulate an evasive maneuver. And this is really where I noticed the airbags it seems like the most, when we're hauling a lot of heavyweight and things like that.

With the addition of the airbags, it helps out a lot with reducing sway. So we're going to go ahead and get into it now.And again, the suspension on this truck is actually pretty good. It does got a little bit of sway here, but it's not terribly bad, but I expect the bags to really make a big difference there. And the more weight we load this up, the worse it's going to be. So I can see where, when you're putting this truck towards its upper limits, that it could get a little bit squirrely there.Now that we've got our airbags installed, we're going to go ahead and hit our test course once again, to see how it differs.

We're going to start in the uneven bumps section again, and I can definitely feel there's a difference there in the back. It feels quite a bit stiffer than it did before. It's not uncomfortable, but you can definitely feel a little bit more of an impact. There's less kind of bounce to it and it's just more solid.Next, we're going to be going into our even bump section. And this is going to mimic going over a speed bump, or in and out of your driveway. And here we come up on this one, and it's really not too much different than the uneven bumps section. You can definitely tell it's a little stiffer, there's less bounce in the back. Once we go over that bump, it kind of immediately levels itself back out without a bunch of up and down oscillations. We're now going to head into the slalom section, and this is usually where I notice it quite a bit, because it does work with reducing sway. As we want to load down, as the weight wants to shift to one side, that bag wants to push it back up to keep us upright.And wow, yeah, it does feel pretty darn good here in the back. You can feel it's really stiff, there's almost no sway. It had great suspension before, but it definitely feels like it made a big difference in the amount of sway that we've got here. I mean, you can really almost. it has like no roll. It's just kind of us going around a little bit in here.And this is what our airbags look like. You can see here that they are double convoluted design, which increases their burst pressure. And being the XL series, this is actually a slightly larger diameter bag than what the regular 5000 series would be. These have a seven inch diameter. Additionally, there's roll plates on both the top and bottom, that further help increase its carrying capacity and burst pressure. With all of that, the XL series bags here are able to support up to 7,500 pounds of weight. Now that doesn't increase the carrying capacity of your truck, this is just how much it can assist in supporting to help level your suspension back out. And that's also going to help smooth out your ride.The XL series here, with 7,500 pounds, is about 2,500 pounds higher than the regular Air Lift series of LoadLifter, which is only about 5,000 pounds. So if you need that extra carrying capacity, then I highly recommend the XL series. These bags operate between five and 100 pounds of pressure. Five is typically for your unloaded state, when you're just driving your truck around normal. You do want to make sure you have at least five pounds in there, because that can keep your bags from, when they expand for moving over bumps, it can keep them from sucking in and collapsing on themselves due to a vacuum being created. So that five pounds helps it keep its shape. And then when you load it down, you can increase that pressure to level out your vehicle. And in most cases, you're going to be increasing it up to maybe 40 or 50 pounds. Beyond that, most of the time you don't need to go that high, and your suspension usually does get pretty stiff. But if you're really loading your truck up to its maximum, you may need to increase the pressure a little higher than that.And another thing I like about the kits is that it comes with everything you need to get them installed, and there are no drilling required. All of our brackets are going to mount up right onto the vehicle. You get all the clamps and hardware you need. Our customer had put a set of the XL bags on his Super Duty here, for hauling his fifth wheel trailer. And when you're hauling a big trailer like this, once you hook up to the back, it sags down the rear of your truck. And what that does is it changes the geometry of your suspension. So you're losing handling performance, and you're also wearing your tires more. The tires don't have as much contact to the road as it did. There's less surface area. You've also shifted more of the weight towards the rear. So when you go to stop, the weight's not properly being applied onto the front axle, which reduces your stopping distance and your braking performance. And lastly, it also lifts your headlights up towards the sky, which reduces your visibility when seeing at night.We can hook up our trailer now, and then air up our airbags. That's going to level our truck back out, restoring our suspension's geometry to the factory setting, which gives us more contact against the road with our tires, and it gives us more control over our entire rig. Something like this is going to make a big difference in reducing the white knuckle driving that you're going to do, because you're going to have that restored performance, both breaking and handling, which is just going to make you feel like you have so much more control over this big, heavy rig.And they're also useful if you want to get some work done. If you've got some projects at home, you stop by the quarry and you get a bed full of rock at the back, that's going to load your truck down quite a bit. And it's going to reduce that performance like we talked about, just like with the fifth wheel. Our airbags can correct that issue as well, so you don't feel unsafe on your way home. And it's also great for your heavier bumper pull trailers, such as a horse trailer, or things like an in-bed camper.Now, one of the things I would recommend in addition to your airbags is a compressor system, because oftentimes when you're going to be using your truck, you may not be in a location where you can air it up or deflate it. Maybe you get to your camp site, and you just unhooked from your trailer, which you want to run up to town to get some supplies, but you've got all that air pressure in your bags. Sure, you can let it out. But then when you go to hook back up to leave, you're going to have to find another spot to air up.Having a compressor on board will allow you to do so. And it's great, not just for those camping scenarios, but especially for work scenarios where you're constantly loading and unloading your truck. You can adjust it to have the best ride quality and performance every time, regardless of what you're hauling. You're getting right on board, air them up, good to go. You can pick up an air compressor from Air Lift here at etrailer. I highly recommended their wireless, EZ Mount compressor. It's one of the quickest and easiest to install. And in my opinion, it has the best performance out of all the manufacturers. And that completes our look at Air Lift's LoadLifter XL series airbags..
