Air Lift LoadLifter 7500 XL Air Spring Kit for 2020-2026 Chevrolet Silverado 2500HD & 3500HD, 2020-2026 GMC Sierra 2500HD & 3500HD - 57541

Work great. Easy to install. Highly recommend. Using them on my GMC 2500HD with fifth wheel camper with 3500 lb pin weight.

Install was ok, messing around with the ubolt combination leaves a bit to be desired for the upper mounts. I think the upper mounts should be more outboard than they are but the jounce cup lip doesn't fit in the cutout of the upper mount so you only get so much. I don't like that the uppers sit at a bit of an angle from the bottoms. Maybe I'll clearance them a little later so they are more directly inline top and bottom so the airbags are straight. If you have a Banks Monster Exhaust, call it a tailpipe but not to their faces or you will offend them, you may have some clearance problems as they only offer a 5" "tailpipe" now for their dpf back system. I had to slide the whole works back about a 1/2" from the dpf so the upper bag mount wasn't right up against the exhaust. There isn't a lot of room for both oversized airbags and oversized exhaust so gotta play around a bit to make it all work together. You will also need 5" hose clamps to secure the heat shield as they assume you are attaching to the stock 4" exhaust.Ride was nice, only needed 25psi to level out the squat of 3700lbs pin weight on my 23 GMC doodly. Wanted the higher capacity bags so I'd need less air as opposed to going with the 5k bags like I had on my last truck. I had 5k bags on my old truck and at 70psi the ride was much stiffer. Unloaded I run them around 10psi and will keep playing with those pressures both loaded and unloaded to eek a little more ride comfort. It's a one ton so it won't ride like a caddy, but I can sure try to tweak it a little. Also reused the wireless one air pump unit thingy and installed it as well at the same time. Total install 3-4 hours or so.

Installed and they fit & Work well

Airlift is a great company and makes the install easy! I hold a lot of weight in my truck and it took care of it and makes it feel like there is no weight back there!

Anyone that’s going to do any serious towing with their truck needs these. Install wasn’t to bad took about 6 hours. Wish the directions were a little better, and I would not attempt without a lift.

These things are beefy. If you have a 1-ton pickup with a heavy load, these will easily level your truck and help smooth out your ride. With the truck unloaded, I did not notice any difference in ride with the minimum 5lbs of air. After hitching a 5th wheel with 3K pin weight I would get 2 inches of squat until the truck came in contact with the upper overload springs. Airing up to 55lbs helped level the truck and smooth out the ride.Installation was straight forward following the included instruction manual. I had also watched some videos as well. I did come across a neat trick where you cut about a 4-6 inch length of air tube for each spring and insert it into the fitting. Then you compress each spring, and when compressed plug the open end of the air hose (I used golf tees.) This keeps the spring compressed and make it easier to maneuver into position. Once in position, remove the short piece of air hose and the spring return to their resting position/size, and ready for the rest of the install.Really the hardest part of the install was trying to determine how I was going to run my air lines. I did get the WirelessOne compressor with easy mount, but I did run one line to the rear license plate for my manual inflate/deflate option if needed.

They were relatively easy to install. Took about 3-4 hours by the time in found tools needed. Figured out rear lower mounts were in wrong spot. (My fault) Need to be as far back as possible. Overall very good. Haul a LUXE Toy Hauler with close the 5k pin weight. Brought rear end up almost 1.5 inches. Much more level. At 10 lbs truck rode smoother without a load over speed bumps, etc.

Install wasn’t bad if your a handy person, they are very well made and my truck no longer squats when towing heavy bumper pull loads
