Air LiftLoadLifter 7500 XL Air Spring Kit for 2020-2025 Chevrolet Silverado 2500HD & 3500HD, 2020-2025 GMC Sierra 2500HD & 3500HD - 57541

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.

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!

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.

Installed and they fit & Work well

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.

Third time getting this kit. Works great, makes towing much more comfy!

Solid product, better be good with tools to install yourself but doable for a knowledge handy man with common sense.

Said it fit a 2020 dmax and they sent me kit for a ford 🤦🏽‍♂️🤦🏽‍♂️🤦🏽‍♂️like if they can’t tell difference between ford and a Duramax
