Photo Comparing LoadLifter 7500 XL with LoadLifter 5000

LoadLifter 7500 XL Ultimate 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.

  • Air Lift Air Bag and Compressor Kit for 2019 Ford F-250 with 6 inch Lift
    Hey Jimmy, so we can't get Fox shocks but we can help with an Air Lift air bag and compressor kit. The correct part number for the air bag kit would be the part # AL57577 and since you have a 6 inch lift you'd need the spacer kit part # AL52460. For a compressor kit I would go with the WirelessONE part # AL25980EZ which can be controlled with the included remote or your phone.

  • 7,500 lb Capacity Air Bag Kit that Fits 2025 Ford F-450
    Hey Robert, there was a big enough change between the 2022 and 2023 models of the F-450 that Air Lift had to release a new fit for the trucks. So for your 2025 F-450 you would need the Air Lift LoadLifter 5000 part # AL57399. It's pretty common with newer trucks that fits change often as vehicles are updated pretty often now. Do you have a compressor? With that said only Firestone has a 7,500 lb bag kit available for your truck and for that you'd need the part # F95FV.

  • Air Lift 5000 or 7500 Air Bags For 2019 Ford F-350 Super Duty 4x4 Towing 5th Wheel
    Hey Brent, Good question and for your 2019 Ford F-350 4x4, I would go with the Air Lift LoadLifter 7500 XL Ultimate Air Helper Springs # AL57577. Compared to the Air Lift LoadLifter 5000 # AL57399, the the 7500 XL are going to give you the best load-leveling both now and, like you mentioned, into the future. The ride won't be rougher than the 5,000 lb bags if you keep them at a low psi, as the internal jounce bumpers on the 7500 XL won't be engaging. The 7500 XL # AL57577 are also larger...

  • Air Lift Air Bag Suspension Enhancement Recommendation for 2018 Ford F-350 Dually
    Air Lift makes several different lines of air bag suspension that fits your 2018 Ford F-350 but I'd need to know which exact kit you bought. I also am not seeing any fits that exclude dually models of the truck either. To offset the cost of the kit you bought that does not fit it might be worth considering selling the entire kit you have as a whole and buying the correct fit your truck part # AL57577. If you replace the brackets you have currently you'd be left with extras that you'd...

  • Will the Air Lift AL57577 Fit a 2019 Ford F-350 Dually Diesel
    The Air Lift LoadLifter 7500 XL # AL57577 will fit your 2019 Ford F-350 dually with the Diesel engine. I did some looking and was unable to find any caveats for the diesel models for this year. Though we do not have an install video of this on a dually, I did include one we did on a single wheel model.

  • Will the Air Lift 7500 Air Bags Fit a 2019 Ford F-350 DRW with Pucks
    I checked with Air Lift and can confirm the LoadLifter 7500 XL Air Helper Springs part # AL57577 will fit your 2019 Ford F-350 DRW with the factory puck system. This kit is a direct bolt-on option so no drilling will be required and it is also made right here in the USA. In order to complete your setup I highly recommend an air compressor system because this allows you to adjust the air pressure at will, as needed for different loads. The best option for this is the Air Lift WirelessAIR...

  • Air Lift Suspension Kit Recommendation for 2017 Ford F-350 Towing Fifth Wheel
    Most vehicle suspension is progressively rated like what you mentioned. That means that the further the suspension compresses the stiffer the suspension becomes to bettery suit heavy loads. That said air suspension enhancement like the Air Lift kit part # AL57577 will still provide more support that will be helpful. It helps support the suspension when needed to provide you with the best possible towing experience. What's great about air bags is that when needed you can inflate them to...

  • Air Helper Spring Fit for 2022 Ford F-450 DRW King Ranch
    Air Lift doesn't list an application for the 2022 Ford F450 DRW pickup, but the good news is that Firestone does. This is actually preferable, because Firestone joins the rubber air springs to the upper and lower plates using a roll crimp, which is stronger and therefore more reliable in the long run than the band clamps Air Lift uses to join the bags to the plates. For a system that provides 5000 lb of support, use part # F35FV. A 7500 lb kit is also available as part # F95FV. You might...

  • Will the Air Lift Springs Part # AL57577 Fit a 2018 Ford F-350 with 5th Wheel Prep Package
    I spoke to my contact at AirLift and they informed me that the Air Lift LoadLifter 7500 XL Air Helper Springs part # AL57577 will work with your 2018 Ford F-350 that has the factory 5th wheel prep package. They have not experienced any issues with this setup on vehicles with a factory prep package therefore am confident that it will also work for you. If you would like to add an on-board compressor which will eliminate having to exit the cab of the truck and find access to an external...

  • 5th Wheel Hitch Compatible Air Helper Spring Recommendation for 2019 Ford F-250
    The AirLift LoadLifter 7500 XL, part # AL57577 and the Firestone # F35FV are both a confirmed fit for your 2019 Ford F-250, and both are compatible with in-bed hitches. I'd personally choose the Firestone option, because their crimp sealed spring end caps doe a better job attaching the rubber spring to the end caps which are more durable than the band clamp arrangement used by AirLift. Plus, the 7500 lb capacity of the # AL57577 is more capacity than most folks would ever need. You might...

  • Air Lift LoadLifter Fit on 2019 Ford F-250 With 6" Lift Kit
    It looks like the Air Lift LoadLifter 7500 XL # AL57577 will bolt up on your 2019 Ford F-250 with the 6" lift. Your lift kit moved the overload bracket that contacts the stock bump stop which is where the bottom bracket of the air bag will mount. To ensure that you have the correct height you will need to park your F-250 on a flat and level surface without any extra weight on the rear suspension. The air bag has a working height of 7" between the mounting brackets(see image). If the 7"...

  • Is a Lift Spacer Required for Air Lift Airbags on a Lifted 2017 Ford F-250
    Thank you for the photo! In your case, you are correct in that you will not need a lift spacer to install the Air Lift LoadLifter 7500 XL Air Helper Springs part # AL57577 on your 2017 Ford F-250 as the distance between the contact point and jounce spring has not changed. This is the case for most newer Ford trucks with lift kits installed. In order to take full advantage of these airbags you might also want to consider an air compressor system like the Air Lift WirelessAIR Compressor...

  • Recommended Air Bags and Compressor System for a 2019 Ford F-350 4x4 SRW
    For your 2019 Ford F-350 4x4 SRW, I recommend using the Air Lift LoadLifter 7500 XL Air Helper Springs part # AL57577 because they have the highest rated capacity of 7,500 lbs and they will work with an in-bed 5th wheel/gooseneck hitch. These airbags are also a direct bolt-on fit with no drilling required. Then for an air compressor kit, I recommend the Air Lift QuickShot Compressor System part # AL25690 which has the heavy duty air compressor, on-board tank, single psi gauge, and single...

  • 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.

  • Are Spacers Needed for Air Lift Suspension Kit on 2019 Ford F-250 with 6 inch Suspension Lift
    Since your truck lift is a suspension lift (adding distance between the frame and axle of the truck) you will need to use lift spacers to take up that extra space so that your Air Lift bags engage like needed. If the height added is 6 inches the lift spacers you'd need are # AL52460. A lot of times 6 inch lifts are more like 4 inches which if that was the case you'd want the part # AL52440.

  • Suspension Enhancement Recommendation for 2018 Ford F-350 with Factory 5th Wheel Rail Kit
    We have suspension enhancement that does fit your 2018 Ford F-350 with an in-bed fifth wheel rail kit installed, but the Air Lift and Firestone kits you mentioned will not fit due to the rail kit. Instead we have the Timbrens part # TFR350SDJ which are a confirmed fit for your truck, will give you the support you want, and are compatible with the in-bed hitch. What's also great about the Timbrens is that they install much easier than air bags and you never have to mess with inflating or...

  • Compatibility of AirLift Air Springs with 2017 Ford F-350 Dually with Factory Gooseneck Hitch
    The Air Lift LoadLifter 7500 XL Air Helper Springs - Rear Axle # AL57577 is only compatible with the 4WD version of your 2017 Ford F-350 Dually. If you have 2WD, I recommend the Air Lift LoadLifter 5000 Air Helper Springs - Rear Axle # AL57391. I reached out to the manufacturer and both are compatible with the factory gooseneck hitch. Both come with the manual inflation valves, but if you want to have adjustability at all times, I recommend the Air Lift Load Controller Compressor System...

I reached out to my tech contact at Air Lift to confirm this for you. You may also be interested in the Air Lift Load Controller Compressor System for Air Helper Springs- Heavy Duty - Dual Path # AL25856 or the Wireless unit # AL74000. Either system allows you to monitor and adjust the air pressure in your springs from the comfort of your cab at any time....

    Yes, the Air Lift LoadLifter 7500 XL Air Helper Springs # AL57577 will fit with your 2019 Ford F-250 having a PullRite sliding 5th wheel hitch. I recommend installing the Air Lift WirelessAIR Compressor System # AL58WQ when you install these springs. This compressor system uses a smart manifold which you can control from your smart phone using the Air Lift app. This means not remotes to carry or air lines and gauges to run inside your cab. Best of all the smart manifold monitors air pressure...
