Had to do some adaptation for my application. I still need to run down a leak that started about two months after use. 673875


Comments
If an air bag suspension is going to leak, it will typically do so at the point where the air lines into the fittings. Its crucial that when the air lines are cut to length, the cut needs to be perfectly perpendicular or it will leak. Brushing a solution of dish washing liquid and water on the fittings and then looking for the bubbles is the easiest way to locate the leak.

2018 Ford F-350 Super Duty

A year after installing this I'm happy to say that this kit is still working great. I use it to tow an 18k lb 5th wheel trailer (3200lb pin weight) with my 2018 F350 SRW and it rides so much better and safer. Installation was a breeze, and everything seemed very high quality. It's been near the ocean it's whole life with frequent trips to salted snowy roads and there are no signs of rust. And with the larger air bags I can keep the pressure lower in them (60psi) and not have to worry about exceeding limits on hard bumps etc. All in all I would buy these again, and believe they are an absolute must for anyone towing a large load. 651151

Box arrived on time and in good condition. I opened the box and removed all parts, nothing was missing or damaged. I am very impressed with the quality and how well parts are made. I did a pre assembly and everything seems to be okay. I will update after I install the airbags. 729792

Installed on my ‘19 Sierra 2500 4x4 diesel. Installed professionally February ‘19. Vehicle came factory with 5th wheel hardware, but with a little work, they attached just fine. Used in conjunction with my OBA system these bags both improved the ride quality of the truck empty, as well as loaded and towing. I tow a 24’ travel trailer full time. These bags improve the ride dramatically, especially depending on the road surface I’m on. Absolutely problem free. No air leaks. No bag failures. Very satisfied in over 30k miles. 744948

2018 Dodge Ram 3500 dually 4 wheel drive with 6.7 Cummins. My Fifth Wheel tongue weight was around 4500 pounds. It would make my headlights at night blind people on road. And my steering wasn’t that great! After installing these Air Bags my lights and steering are so much better. Installing these air bags I did it myself on ground. No jacks truck on level ground. I put together everything. Then went under truck on my back. Mounted the top mount. Then I took strap and smash the air bag down to fit. After in place I took strap off. And bolted it all up. Took me 30 min. Per side. Very easy to install. Just basic hand tools needed. I buy a lot of stuff from etrailer they have the finest stuff at excellent prices. They have my business for life! 692501

Review from a similar LoadLifter 7500XL in Vehicle Suspension


Hello George, I purchased the Air Lift Load Lifter 7500 XL Air Helper Spring kit for my F450 Ford Dually. I pull a heavy 5th Wheel Trailer and wanted something to raise the rear if the truck when the 5th Wheel was attached. I run with about 4,200 lbs, pin weight and these air lift bags did a great job at leveling things out once hooked up. The kit was very complete, good instructiona and fairly easy to install, (I used a four post lift to install this kit, but it could be installed at home if necessary). I typically run about 60 lbs air pressure in the bags (when loaded), and get about 1 1/2" of lift with that pressure. When empty, I run 5 - 10 lbs. Great product!! John 871646

The install was a breeze about 4 hours, we have traveled several thousand miles with our 10 foot Lance camper loaded on back, while towing a side by side on a tandem axle trailer. The added support made the stability much better, we also installed the twin beam receiver about the same time. Happy trails good investment. 809184

I added this to level my truck when hauling heavy loads like my truck camper. It took longer than expected to install, but the documentation was comprehensive. Plan on an all day installation with two people if you have never installed one before. I haven't driven the truck with the camper installed yet, but confident if will meet my needs. 794267

Review from a similar LoadLifter 7500XL in Vehicle Suspension


I just finished the airlift 7500xl install on my 2020 Duramax dually and because of the 5th wheel prep doesn’t allow for the top U bolts to go into position. However if you remove the rear six bed bolts and loosen the front two about half an inch than lift the rear of the bed from the rear. I used a piece of cable and D-rings in the lower in bed tie downs and an engine hoist tow lift the bed about an inch in the rear being careful not to let the bed hit the cab- This allowed for the bolts to slide under the bed supports and into place Hope this helps someone. 793364

  • 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...

This kit is a direct bolt-on option so no drilling will be required and it is also made right here in the USA.

  • 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.

    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.

  • 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.
