Air Lift LoadLifter 5000 Ultimate Air Spring Kit – Fits 2007-2019 Chevy Silverado/GMC Sierra 1500 Legacy With Short & Standard Bed, 2019 Chevy Silverado/Sierra 1500 Limited – 88204

Great set of bags, getting the one with the internal bumper is worth the extra money, trust me! I've already had my air line come apart (Totally my fault for not paying attention during installation). This is my third truck with air bags, only way to go if you've never had them. This is my first set of AitLift bags, I've always had Firestone RideRite before. Honestly there is no real difference between the products. The no drill mounting and location are identical, the quality of the bags are equal. To me it comes down to which ones you can get for cheaper at the moment you are ordering them.Now if you're not sure if you should install single or dual path then do both. If you are buying a compressor rig for dual path for twice the money because you might need it once in awhile DON'T, get the single path and think about it! The beauty of air lines is that you can actually do both for a back up. Go to a napa truck center, or any tractor trailer parts store (Or order on here) and get a 1/4" air line valve and put it in between. However from their plumb the rest of the system as single path (so if that confused you, plumb dual path from the back of the truck to the bags. Plumb single path from the compressor to the bags. then install a shut off crossover line between the back lines) This will let you run the system single path (crossover line open) on a normal day for everyday ride, or single point hauling such as a bumper pull trailer. However if you have a random side heavy load, air it up until the heavy side is riding where you need it then close the crossover valve and bleed the lite side down until it's riding rite (or you can inflate each side thru the Schrader valves if you have access to an air fill station at that time)I actually put mine together with a 12v ball valve on my crossover line so I now have a switch inside the cab for single/dual path. I also installed a push button bleed valve for each side so I don't have to bleed off the Schrader valves. Final hint, air line and fittings are way cheaper at a napa truck center or a tractor trailer parts store. You can also find the other things I've been talking about. Good luck.

This is my second set of airlifts. last set was the 5000. By far the best money I've spent for towing, leveling the truck out takes care of sway issues and handling issues when pulling at the upper end of your rating. The ultimate seems to require less air than the 5k, maybe because its a different truck but 15psi in the 5k on an '05 silverado 1500 was a comfortable empty ride with almost no lift (45psi 900lb tongue, 7000 trailer), on '16 sierra 1500 15psi lifts the rear better than 2" empty and ride is stiffer, I suspect the inner buffer that allows you to run them at 0psi has something to do with it. customer service is awesome with airlift, on both sets I was missing or had incorrect components (2 left upper mounts, missing bolts), called airlift and they just ask for your address and the send the right parts out, got them in 2 days. install is pretty basic if you've ever turned a wrench. I did use a different air line because the airlift stuff wouldn't stop leaking but still give the product 5 stars for how it works and the ease of install.

I put these on as a last ditch before going to a larger tow vehicle. The best way I could describe my towing experience with my large RV trailer was a small boat bobbing in moderate seas. While this product will not bolster your GAWVR, it will stabilize the snot out of it. I put these on and after attaching the trailer, I put 20lbs in each bag and went camping. The ride was WAY better. The bobbing and rocking, even with a 4-way sway hitch, made for a more comfortable ride. One which, I may add, did not leave me with a clenched jaw for 4-6 hours.The rear end tends to be a little stiff when not under load, so make sure to air back down and follow the instructions Airlift provides. You do need to check the air at least monthly. Make sure you don't lose a socket in the frame!

Work well and like the added capacity and ride height improvement. Connected both side together in one air circuit. This way the pressure is the same for both sides, while towing the trailer. I find that keeping 4 to 5 Psi in system works well. When weight is added, the pressure rises up to the needed system loaded pressure (approx 24 to 27 psi) to keep the truck level. The unloaded ride is a bit rougher, but not bad (hence 4 star rating)... One could reduce the pressure to 1 psi if needed (Yes, you can run zero psi if wanted... I prefer some air in system). If you are going to connect both sides together you will need the Air Lift Union Tee 21838. Mounted my Air Fill in the rear bumper under the spare tire lock, there is a plastic filler panel there and is easy to drill a hole. Be sure that it is low enough not to interfere with the spare tire lock in a 2015-2017 Silverado. Also ran lines through the frame using existing frame holes from the axle back to bumper. Very clean install.I have AirLift Air Bags in the rear springs on another vehicle... They are about 15 years old... They work...

Ok guys, I installed this kit on a 2015 GMC Sierra 1/2 ton. The kit was delivered on time, well packaged and wasn't missing any parts. I'm an average mechanic with average tools and the total install only took about 3hrs. The install was done from the sides with the tires removed, the only time I went under the truck was to install the air lines and the bracket that bolts to the differential. I removed the fender liner on the drivers side to install the U-bolt because there are some fluid line that run on top of the frame that you don't want to pinch and I couldn't see them with the liner in. The install was a snap, everything fit perfectly, the instructions were complete and easy to follow. I also ordered the "T" fitting so I would only have one fill fitting which I installed on the drivers side by not reinstalling one of the torx screws that held the fender liner on and using that hole, that way I didn't have to drill a single hole to complete the job. So, it was easy to do and the system works great.
