Photo Comparing LoadLifter 7500 XL with LoadLifter 5000

LoadLifter 7500 XL springs have up to 20 percent more air spring volume than LoadLifter 5000 springs. The available volume in these 7" double-bellows air springs enable greater leveling strength at lower pressures. This ensures maximum load-lifting abilities and a great ride quality no matter the load.

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.

2006 Chevrolet Silverado

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.


Game changer for towing heavy. I got manual bags. Didn't want the fuss of running wires and managing more automation. Have had installed for 1 year thereabouts.

Super simple. Hook up, air up and go. I keep a little dc compressor so I can just air up right off the truck.

I did my own install. I'm Not even close to a mechanic. Hardest part was removing the old corroded hardware on the trucks.

Highly recommend


Easy to install. Follow step by step directions and you’ll have no issues. I found that removing the spare tire was necessary and by doing so it gave me more room to work.


Great product


Easy install. Excellent performance. Great fitment.


Easy install. Works great, other then one side leaks and needs to be refilled quite often if towing for a trip.


Did a great job.With gooseneck & bumper pull trailer.


Customer service is second to none! Alex J. was very helpful submitting my "price match". Will be installing soon.

2020 GMC Sierra 3500

Looking up the application for my vehicle was simply, straight forward and parts were delivered promptly. I will continue to use etrailer for future purchases


The product was exactly as advertised but without a lift it was impossible to align the bolt holes so I do not suggest tackling the job without a lift. It has functioned perfectly to this point


Everything looks good and built well, I will send more in a couple weeks when I have time to install them.


Great kit! Easy and quick installation.
have had them on three RV pickups.....definitely smooth out the trip.
The TX Winter Storm created a two week delay in delivery, it sat for two weeks in a warm UPS warehouse


Great product and easy install!


Very good

2004 Chevrolet Silverado

Shipping was fast. Install was easy. Now to test them out and see how I like them.

Review from a similar LoadLifter 7500 XL in Vehicle Suspension

I have a 2020 Ford F-250 Lariat FX diesel and I pull a 2022 Jayco Eagle HT fifth wheel with a GVWR of 10,995 lbs. I noticed when I was hooked up to my trailer and raised my landing gear the back of my truck would squat causing my headlights to shine somewhat into the sky and sometimes while traveling the interstate in construction zones the ride was rough. So I decided to add airbags. I chose the Air Lift Load Lifter 7500 XL Air helper springs(#AL55FJ). I had them installed by a local garage and he did a great job installing them. I love the end result a much smoother ride and the braking seems smoother also I can easily level off my truck with the 7500 XL Air lift system allowing my headlights to shine straight out now. I give these guys five stars.

In addition to adding the Air Lift 7500 XL system I also had the Air Lift Wireless Air compressor System(#AL58WQ) installed and it is Bluetooth, compatible on my iPhone which is amazing. I can control the lift on my bags individually or paired together with the touch of my phone. No stopping and getting out in the rain or looking for an air hose. I can sit in my cab or get out and increase or decrease the amount of air in my Air Lift system. I can also do it manually if I so choose. In the photo you can see where I mounted the two air fitting on my crossmember right below the compressor on the frame. There were already two holes there so and can be accessed easily. I am very satisfied with my compressor system and I give this a thumbs up in addition to the five stars.


Review from a similar LoadLifter 7500 XL in Vehicle Suspension

Easy install. Would recommend to anyone hauling heavy trailers. Especially with the newer Ford f350. Helped the ride while towing gooseneck and fifth wheel 100 percent.

  • Is There an Air Lift 7500 XL Series Suspension Kit that Fits 2002 Chevy Silverado 2500HD
    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.

  • Fit of Air Lift LoadLifter 7500 on 2006 Duramax With Relocated Shock Absorbers
    The AirLift # AL57575 is designed for a stock suspension setup, and without knowing exactly how your specific suspension is set up, I couldn't say with certainty whether the # AL57575 would fit. What I can do however, is link you to the installation instructions which show full-color photos of exactly how the # AL57575 Load Lifter air helper springs will sit on the vehicle once installed. You should be able to compare the photos to your existing suspension, and determine if everything...

  • Air Bag Mounting Location on a 2006 Chevrolet Silverado 2500 HD
    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...

  • Will Air Bags Fit 2007 Chevy Silverado 2500HD With Fifth Wheel Hitch
    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...

  • Air Lift WirelessOne 7500XL Fault Code
    I did check with Air Lift directly and they said the A 14 Comp Open error message for kits like the Air Lift LoadLifter 7500 XL Air Helper Springs # AL57575 usually indicates a bad compressor ground. Moving the mounting location for the ground or wire brushing the ground connection area to ensure a clean connection is made will usually address this code error.

  • Recommended PSI For Air Lift LoadLifter 7500 XL Air Helper Springs on 2007 GMC Sierra 2500
    I believe you are referring to the Air Lift LoadLifter 7500 XL Air Helper Springs part # AL57575 for the 2007 GMC Sierra 2500. There is not a specific PSI per LB of weight when it comes to the Air Lift springs. They can be adjusted between 5-100 PSI. I recommend to fill them until your setup is level but do not exceed 100 PSI. It it easier to use a compressor if you do not already have one I recommend to take a look at the Air Lift WirelessAIR Compressor System part # AL74000. This will...

  • Compatibility of AirLift LoadLifter 7500 XL Air Springs on 2005 GMC Sierra Utility Body
    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.

  • Recommended Air Lift Air Helper Spring System for 2006 Chevy Silverado 2500HD
    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.

  • 2 inch Air Lift Spacer Kit for Loadlifter 7500 XL Air Helper Spings
    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.

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.

  • Do Air Lift LoadLifter 7500XL Air Springs for 2001 Chevy Silverado 2500 have Internal Jounce Bumpers
    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. I agree with your solutions to the problem: moving weight around and adding additional support. You could...

  • Which Air Bag Suspension Kit Is Best For 2021 Ford F-450 Super Duty 4x4?
    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.

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.

  • Recommended Airbag Kit for a 2009 Chevrolet Silverado 2500HD
    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...
