Air Lift 89338 LoadLifter 5000 Ultimate Plus Air Suspension Kit

Awesome product! Easy install! I would recommend these to anyone. Installed these on my 2019 Duramax with a 5th hitch and they worked great!

Installation is super easy. Works great to level my truck back out after hooking to my fifth wheel.

Stiffer ride but worth it. It is a 3/4 ton truck. It’s better to be level than squatted when you are hauling anything.

This is the stainless version and while the plates and lines are stainless the rest of the hardware is not. Its a bummer - i wanted the stainless because i live in in the rust belt. The instructions list several places you can mount the air inlets but the braided lines are only long enough to reach the bumper area - it would have been nice to have them in the gas tank door but the passenger side would never reach that far - despite the instructions indication that installing at that location was an option.These have JIC ends on the stainless lines however they are made very poorly and all leaked when tightened snug,. I had to remove them and reinstall with thread sealant If they are going to use crappy ends the least they could do is provide some teflon or pipe dope to seal them with,. JICs are not supposed to need anything to seal jus 1/6 turn past finger tight but these are craptastic. They do not tell you to do this but I inflated the bags and sprayed all the connections with soapy water to ensure they were not leaking. If I had not done this I would have had trouble.After everything that they are nice bags. I put them on my GMC 2500 and it nicely leveled it with the truck camper on. It takes some effort to get the pressure right. They don't really give instructions on how to set them and they really should. If you put just enough pressure in them to separate the overload spring from the main pack you get a good ride with level headlights. They do not take much air at all, inflating from shop pressure takes some effort to get right, they inflate very fast and if your trying to get to say 20 PSI on both its tough. Understand that you need to set the pressure with the load on the truck because 5psi with the truck empty could be 15-25 with it loaded. It makes sense, PV=NRT from physics and all but again its not explained in the manual. when i set them at 5psi and then put the camper on they were at 18. If you had them to high with the truck empty you could be over the PSI limit on the bags with the truck loaded.Overall, the install was easy and not at all time consuming, just frustrating because of the leaks. There is on the gas tank side a bastard bolt that you cannot get to with a torque wrench and have to just snug up by feel because the gas tank skid is in the way.I just used this for a 1200 mile trip with the truck camper right after installing them and highly recommend them for improved ride quality and keeping your head lights level .

These should come installed from the factory for all hd trucks. Installed easily on my 2015 Silverado 2500hd longbed. Took about 2 hours for the bags and another hour for the wireless one compressor. Made a huge difference when towing heavy loads. Being able to level the truck out with 15000lbs on the back helps just about everything. Steering is better, no floating. That white knuckle disconnected feeling went away after installing these. 35psi makes the truck feel as it should have from the factory when loaded. Why call any truck heavy duty and not include these is beyond me. Why does GM think we buy these trucks, for Sunday strolls? Headlights shine where they are supposed to. If you use your truck to tow and pull heavy loads, or if you have a long bed and bumper pull anything. Buy these and the wireless compressor. Be investment you can make in your work truck. I also installed the rear Hellwig Big Wig anti sway bar with these. Together it made the 2500hd a different truck when towing, and aired down to 5psi unloaded I can't tell any difference in the ride quality. I'll be installing these on my new silverado dually just as soon as it gets here.

I leveled my truck, so when i hooked up the camper, the truck was sagging, big time. Installed these, inflated them to 60 psi and —— perfect, was riding level! It does add some tighter shock absorbent but, a truck is a truck, I’m ok with it.

I previously ised the Firestone bags on a different truck and really liked them. I sold that truck and needed to add air bags to my new truck. I started pricing them and these bags had very good reviews and the price was much cheaper than the Firestone bags.My first tow with them I wasnt very happy with the ride. Come to find out the bags were deflating. Checked for leaks and found where the air tubing was leaking at one of the push in fittings due to the cut not being square. I trimmed the tubing and put it back together and they have worked great since then. (The cut on the tubing could have been my fault but Im pretty certain that wasnt a cut I made, but it could have been). Other than that cut the bags have worked great and really help the ride when I am towing. My 5th wheel is a 2002 32' trailer than weighs approx 12k. With about 44 psi in the bags the truck rides great. My truck is a 2011 GMC 2500 Denali HD Duramax 4x4.

I installed this on a 2015 Silverado 2500HD with a 5th wheel. I was originally hesitant of this kit when I read "drill into the frame". There are two ways to attach the top. With drilling if the U-bolts won't fit over the 5th wheel attachment. I lucked out and the U-bolts fit, air bags were very simple to install. Had to jack up the truck to allow more room between suspension to put these in. Air bags took about 1hr to install. No leaks, like some people say watch YouTube videos and this will be easy. Required only a few tools.I had a 14 Silverado 1500 and put firestone ride rite. I like the air lift mounting better. The lower mounting is much easier.I haven't towed yet with these but the truck has a much better ride than before I Installed these.I did get a wireless compressor for these which was a pain to install but that's for another review.

Excellent installation instructions and product works as advertised. Installed on a 2016 Silverado and has made towing a heavy trailer much more enjoyable.

Could not ask for a better experience dealing with a warranty issue. They stand behind their products like a company should. Very impressived

Easy install

Very happy easy to install

Good product so far. Works great for hauling a trailer.The bad thing is that I have only had the air bags for a week and both are leaking from the AN 90 fitting, not from the threads but from the swivel part. Kinda disappointed with that as now I have to track down parts and have it fixed.
