Features to know about
Stay Level and Confident Under Heavy Loads: Up to 7,500 lbs of Load-Leveling Support
When you’re hauling a big trailer or heavy bed load, sag and squat can throw off braking, steering, and headlight aim. The Air Lift LoadLifter 7500 XL Ultimate Air Helper Springs give your rear suspension up to 7,500 lbs of load-leveling support to keep your ride level and under control. The 7" diameter double-bellows air springs hold more air volume than the 5000 series, giving stronger leveling performance at lower pressures so your truck stays steady whether you’re towing or loaded down for work.
Smooth Ride Quality Even When Loaded: Large-Volume 7" Air Springs with Internal Jounce Bumper
Heavy loads don’t have to mean a rough ride. The larger 7" air springs on the LoadLifter 7500 XL Ultimate absorb road shock and diminish sway for smoother handling on highways and rough roads. Each spring has an internal jounce bumper that protects against damage if you ever drive with low or no air pressure, so even if you forget to fill the bags, your suspension stays protected and functional.
Dial In the Support You Need: Adjustable Air Pressure from 5 psi to 100 psi
Every haul is different, and these air springs give you full control over how your suspension responds. Adjust each side independently between 5 psi and 100 psi for even load distribution or side-to-side leveling when loads are off-center. Manual inflation valves mount easily on the bumper for quick access, and if you ever want to upgrade, these springs are compatible with compressor systems that let you adjust pressure from inside the cab.
Tough Construction That Lasts: Reinforced Rubber and High-Strength Components
When you’re pulling real weight, reliability matters. Each spring is constructed of 2-ply, fabric-reinforced rubber with high-strength Zytel nylon endcaps that are lighter and more corrosion resistant than steel. Air Lift’s exclusive upper and lower roll plates guard against wear and extend the life of the system. Mounting brackets, hardware, air lines, and manual valves come included so you can install it right and get dependable performance trip after trip.

57575 AirLift Load Lifter 7500 XL Air Bag Suspension Support System - Back Axle
I haul a Northern Lite 10-2 truck camper and the Airlift 7500 air bags are working out great. I have lower stabiloads that work great as well but the camper is significantly heavier on the right side so the airbags help level things up. Adding the on board compressor has been really helpful and I’m impressed with how quickly the compressor fills the bags. I have used it to help level the camper at campsites. As others have said the bolts at the top of the bags can be challenging to install so remove the spare tire and rear shocks to save yourself some trouble. I also made a tapered wooden dowel to make alignment of the bolts easier. Happy with my purchase. 3503616
Installment instructions are very vague for a novice. If you don't have a vehicle lift it is very difficult. 3566102

This is my second Air Lift 7500XL purchase from Etrailer. Each time the and (actually) everything I've purchased here has been great and the experts that have helped along the way have been top-notch. I highly recommend the Air Lift 7500XL bags, I had them on a 2008 Silverado 2500HD extended cab, and my current truck, 2008 Silverado 2500HD Crew Cab. I haul a 20' double axel steel livestock trailer and slide-in truck camper. My family shows livestock and the air lift system handles it all great. 1569104

Nice kit. I got this one specifically because of the upper bracket. It prevents flex on the frame channel while under load. Good install instructions with pictures. 1110331
I’m so glad that I purchased this air lift kit. I originally purchased it for when I was towing the fifth wheel. But it has proven itself over and over again as I tow the tractor, dump trailer, or any other load that needs a lift. Easy to install and the only thing I did differently was to connect the two hoses so that I only had to put air in one time and both sides fill up. Great addition to have. Thanks etrailer! 3384995

Definitely a heavy duty and easy kit to install. Like others have recommended, save yourself the aggravation and take the rear rims/tires off. Also, I used 1/4" expandable braided sleeve on the air lines for added protection against the outside elements. Lastly, if you have an after market exhaust you will need to buy bigger stainless hose clamps for the heat shield. 1709100

Outstanding product. I used my truck with a 14,000lb gvwr trailer this summer frequently. Of course it was probably loaded heavier than it should be but the truck sat level and the ride quality was excellent. Would buy product again! Really easy to adjust pressure to get the ride quality needed with small carry around air compressor.

Doesn’t fit a 2008 GMC Sierra 2500HD without major fabrication. The brake controller bracket prevents the driver side upper bracket from fitting properly. Is this an issue with the Firestone product? If so I’d like a return and replacement. I am not about to cut off my brake controller bracket. I was really hoping to have these installed for my upcoming camping trip. Very disappointed. 1573182

The hard portion of the brake line will need to be bent by hand slightly to ensure it indexes between the upper bracket supports. See figure D5 on page 7 in the manual.

I needed to reseat one of the airlines into a connector on the right side. Also, the right side air line was a little difficult to install due to exhaust pipe and a rather tight curve in the air line. The instructions were unbelievably good, you get a full 5 stars for that. 1680384

This product makes the ride on the truck much smoother while towing and carrying a load. It was fairly involved installing it due to my having a lift kit on the vehicle...which required quite a bit of modification. Overall, I am pleased. 1457769

Etrailer was excellent in pricing, shipping and product information. Great product once installed. The top bolts from frame to air bag are a SOB to get lined up. If Air lift just put some tabs on the bag and holes in the top support to line things up it would be a few minute project, not the hours spent trying to get the 4 upper bolts in. Love the performance once installed. Very helpful in windy conditions in stabilizing ride. Thanks once again etrailer for being by far the best in all ways. 1741483

Hey Luke, we have the Firestone Ride Rite kit part # F2613 that fits your 2024 Chevy Silverado 2500. I really like the Firestone kits over other air bag options as they have the highest quality bags as we have found. view full answer...
You really should go with the Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88275 over the Air Lift LoadLifter 7500 XL # AL57575 for your 2006 Chevy Silverado 2500HD. The weight rating refers to the maximum amount of support they are going to provide your Silverado and since your payload/Tongue weight is going to be below 5,000lbs you will not have any benefit from the 7500. Also as the 5,000lb bags are rated lighter they are going to diminish your unloaded ride quality less... view full answer...
Hey Gene, thanks for reaching out!
For your application I recommend going with the Air Lift LoadLifter 7500 XL Ultimate Air Helper Springs # AL57575 because they offer a higher weight rating at 7,500 lbs so they will have to work less for the constant load on your 2008 Chevy Silverado 2500. These also have an internal jounce bumper so that in the event the unthinkable happens (the air bag fails) you aren't left high and dry.
As is, this kit is manually adjustable via valve stems, but... view full answer...
Yes, it does! You'll just need to add a set of spacers to get the Air Lift LoadLifter 7500 item # AL57575 to fit your 2005 Chevy Silverado 2500. Most 6" lifts aren't actually 6" in the rear. All you'll need is the 4" spacers item # AL52440. view full answer...
Hey Paul, there really isn't any downside to going with the 7500 rated Air Lift kits like the part # AL57575 over the 5k rated kits aside from them costing a little more so for you I would definitely recommend the # AL57575. Are you wanting a compressor too? Did the truck and camper get stolen? view full answer...
Hello Vic,
You can use the Replacement Schrader Valve Fitting for Firestone Coil-Rite Air Helper Springs - 90-Degree # F3438 in your Air Lift air bags.

Hey Tim, such a kit does exist. I recommend checking out the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers # AL88286.
These helper springs will bolt right up to your 2003 GMC Sierra 3500 cab and chassis, has a load leveling capacity up to 5,000 lbs, and an adjustable air pressure range of 5 to 100 PSI. view full answer...
Hello Darren, thanks for reaching out. I am sorry to say that there is not a stainless steel hardware kit available for the Air Lift LoadLifter 7500 XL Ultimate Air Helper Springs # AL57575. I do recommend that you use the hardware that comes with the kit. If you want stainless hardware that is something you would need to source from a local hardware store view full answer...
Hey Nicholas, we have an Air Lift kit that fits your 2004 Chevy Silverado 1500 with the part # AL57250 but the kit you referenced only fits the 2500 and 3500 models. Are you looking for a compressor kit as well? view full answer...
Installing the Union Tee # AL21838 with your # AL57575 will tie the pressure of the two air bags together. So yes, a shift in a very heavy load like a truck camper will potentially result in air being forced from one into the other. The reason I say potentially is because it depends on the pressure you are keeping in the air bags.
If you have them both at the max 100 psi I would expect full support between the two. If you are keeping them at 95 psi there won't be much room for pressure... view full answer...
We have a Firestone air bag kit that fits your 2023 Ford F-550 with the part # F2404 but the Air Lift you mentioned does not fit. The Firestone kit can provide up to 5,600 lb of suspension support. view full answer...
I have an air bag option for your 2023 Ford F-350 Super Duty 4WD, but the Air Lift # AL57575 is only designed for select 2001-2010 Chevy/GMC trucks and won't work on your truck.
Instead I recommend the Firestone # F35FV which give you 5,000lbs of load leveling support which is plenty for 99% of trucks towing on the road. If you have an extremely heavy 5th wheel trailer, or a really heavy gooseneck trailer then you may want to step up to the 7,500lb rated # F95FV instead.
I also highly... view full answer...
When it comes to choosing between the Air Lift 7,500 and the Air Lift 5,000 I recommend going with The Air Lift LoadLifter 5000 Air Helper Springs # AL57275. The 7,500 pound air springs will be over kill for you and will give you an uncomfortable stiff ride. The Air Lift LoadLifter 5000 Air Helper Springs # AL57275 have a 5,000 pound weight capacity and has an adjustable air pressure between 5 psi to 100 psi.
To make life easier I also recommend The Air Lift WirelessAIR Compressor System... view full answer...
Air Lift LoadLifter 7500 XL Air Helper Springs - Rear Axle Item # AL57575 does not have the internal jounce bumper. Those are found in the Air Lift LoadLifter 5000 Ultimate Air Helper Springs line such as # AL88275.
The Air Lift LoadLifter 7500 XL Air Helper Springs # AL57575 have Air Lift's exclusive upper and lower roll plates which are basically the same in all the LoadLifter kits.

The best airbags we have for your 2009 Chevrolet Silverado 2500 are the Firestone Ride-Rite Air Helper Springs part # F2250. These airbags will do an excellent job of helping maintain stability and support when you are using your truck bed camper or towing your 5th wheel trailer. They will also not interfere with the frame brackets you have for your hitch which can be a problem for some airbag kits. I recommend Firestone airbags over Air Lift airbags as they have a stronger sleeve and will... view full answer...
Yes, the Air Lift LoadLifter 7500 XL Ultimate Air Helper Springs # AL57575 are going to be compatible with the RoadActive Suspension # RAS3611-HD. Both of these mount to different parts of your 2007 Chevrolet Silverado 3500 classic so they will not interfere with each other.
I do recommend installing the Air Lift WirelessAIR Compressor System # AL58WQ to adjust the air pressure in the air springs. I prefer this system as it has a smart manifold which allows you to easily control the air... view full answer...
According to our fitguide and Air Lift, their # AL57575 Load Lifter 5000 air helper springs are indeed a fit for a 2006 Chevy Silverado 2500 HD, whether it be a RWD or a 4WD model.
You might also be interested in an on-board compressor kit like part # AL25854 which would allow you to add or remove pressure from the system with the push of a button.
I've linked to a product video for the # AL57575 as well as to a video showing a typical install of the compressor kit I mentioned. view full answer...
The 7500XL series you mentioned only fits the 2500HD models of the 2002 Silverado. That has to be what you have since you have the Duramax Diesel engine. So the part # AL57575 will fit your truck and work well.
The way these install shouldn't be a problem at all with custom exhaust. view full answer...
The space between the top of the leaf springs and bottom of the frame rail on your 2006 Chevrolet Silverado 2500 HD is not ideal for air suspension. I do have an air suspension option for you, however, neither AirLift or Firestone make an airbag kit that attaches to the top of the factory leaf springs on your vehicle. For an airbag kit that attaches to the outside face of the frame rail and on the side of the axle closest to the tire, I recommend using the Air Lift LoadLifter 7500 XL Air... view full answer...
I have a solution for you but no I do not have a taller air bag for the Air Lift LoadLifter 7500 XL Air Helper Springs item # AL57575. The Air Lift Universal Air Spring Spacers for LoadLifter 5000 and 7500XL item # AL52420 are 2 inch spacers. These steel spacers go between the air springs and the mounting brackets, filling the gap between the air springs and your suspension. view full answer...
Yes, the Air Lift LoadLifter 7500 XL Air Helper Springs # AL57575 will fit your 2007 Chevy Silverado 2500HD with a fifth wheel hitch installed and be the perfect way to help keep you level and improve the ride of your truck while you are towing.
I also strongly recommend installing the Air Lift WirelessAIR Compressor System # AL74000 with the helper springs because it has a wireless remote control which allows you to adjust the air pressure in each bag from the comfort of your truck's... view full answer...
The correct Air Lift LoadLifter 7500 XL Air Helper Springs for your 2022 Ram 3500 is part # AL57531 - this will work as long as you don't have a factory air suspension system. I also recommend picking up an air compressor kit like the Air Lift Load Controller System # AL25856 so you can monitor and adjust the air in both bags as needed and you don't have to plan out any stops just to mess with your air bags.
The parts # AL57575 and # AL86KV you referenced are essentially the same thing... view full answer...
The Air Lift LoadLifter 7500 XL Air Helper Springs - Rear Axle # AL57575 will work well for the aftermarket utility body as long as your 2005 GMC Sierra is a 2500 or 3500 model. It will mount directly to the truck without any issues.
If you are interested in a compressor for the air bags to give you that adjustment convenience I recommend the Air Lift WirelessONE Compressor System for Air Helper Springs - Remote - Bluetooth - Single Path # AL25980. view full answer...
For your 2021 Ford F450 Super Duty 4x4, you'll want to go with Air Lift LoadLifter 7500 XL Air Helper Springs - Rear Axle # AL57577.
I recommend adding a compressor kit so that you can adjust the air bags from the cab of your truck. Firestone Air Command I - Analog Gauge w/ Heavy-Duty Compressor - Single Path - 150 psi # F2097 would work well for your setup. I attached demonstration videos that you can check out. view full answer...
