Air Lift LoadLifter 5000 Air Spring Kit – Fits 2011-2019 Chevy Silverado 2500/3500 HD 2WD & 4WD, 2011 GMC Sierra 3500/2500 HD 2WD & 4WD – 57338

Although a little pricey, I found it's a great product. You must be aware, however, that the price is for the airbags ONLY. I bought them along with the wireless one air pump and they work seamlessly. I would have preferred the airbags with the bump stops inside, since the 7500X do NOT have them, but that model only has a capacity of 5000lb, whereas this one can handle up to 7500!!!

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 .

Easy install, did have to make my a unbolt for each side and used one of those provided with the kit to accommodate the turnover ball hitch plate. It was expected so no big deal. I did take the bed off the truck which helps making the new unbolts much simpler. Just 8 bolts a couple of wiring harness plugs to uncouple and the hoist to pick the bed off!

If you tow or haul anything heavy,even occasionally, they are worth it. The increase in capacity when aired up and better ride aired down are well worth the price over constant capacity. Instructions were decent, and put the fill up by my plate.

Like the bags. But on my denali 2500 hd with a front leveling kit. I run about 50 to 60 psi when loaded, when unloaded I have to run 3-5 psi or the ass end of the Pickup is way high !

Not the first time installing this on my truck first time was my 03 chevy 2500 hd . 5 yrs with out issue just bought a new 2019 chevy 2500 hd . instructions could be a little better when it comes to mounting the brackets on the air bags top one is a no brainer bottom one can be a little confusing but once on units slip right in . I did jack up the body from the hitch which gives plenty of room the slide air bags in . take your time running the air lines and use the zip ties . i used a little plumbers grease on the end the fits into the air bag . tested for leaks so far so good .A miust have item for towing RV or carrying large loads . i keep about 1000 lbs of tools and topper in and on the truck bed and these bring me where mi need to be and ride is solid . PS price kept going up daily not by much but it went up i was waiting to order when my amazon point hit my account cost me $2. more dollars by waiting don't know what's up with that guess X-mas

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.

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

Very happy easy to install

Bags are good not so for wireless system manual now after less than 3 years
