Air Lift 25850 Load Controller Single Standard Duty Compressor

I've had an Airlift 5,000 Airbags w/ onboard Airlift Compressor on my 2013 Toyota Tundra. After 11 years in the desert I started having a slow air leak. I pull a 9,500 lb Flagstaff 5th Wheel, so my Air Lift system is an important part.I first purchased new Airlift 5,000 Air Bags figuring it was time to replace the old ones. But the slow leak continued. Time for a new Compressor System. Just installed and it seems ..... problem solved.... Happy Camper !Although my 4x4 Tundra does not squat with the 5th wheel hooked up, it would have bounce up and down on rough sections of freeway Pumping the Air Bags to 55 psi totally takes any bounce out of my suspension.No matter what the towing capacity of a truck, I feel that Air Bags give the ability to give stability under heavy loads or various road conditions.Air Lift is absolutely a 5 star product in my opinion I would never buy anything else for towing heavy loads.In my buying process I called Air Lift Customer Service. Their Customer Service was also absolutely 5 Star. Super friendly and knowledgeable.

This review is made in reference to installing Air Lift Kit 25856 on a 2015 Silverado 3500 dually. This kit comes complete with everything needed to install, minus the air bags themselves. Installation should be done by someone with experience and the proper tools. To work properly and trouble free, the air lines must be cut square to the tubing and inserted fully into the fittings. I used a tubing cutter and found it necessary to remove the burr it left inside the tube to ensure a tight air leak free seal. Over all, the product is well made with a few exceptions. The "Y" fitting used at the compressor is plastic and mine broke easily when installing. A metal fitting would be better and far more durable. Also, as someone else mentioned, the light inside the gauge is not replaceable, so if it burns out, you'll be left in the dark. Speaking of the light, it comes pre-wired into the line that feeds the compressor. If you want the light to operate with the dash lights, you need to clip the power going to the gauge light and wire it into the dash lights. As with any installation of wires or air lines, car should be taken to route them away from potential sharp edges or heat. Also, running the air lines and compressor power line through the firewall requires cutting into the large rubber up-fitter's plug (see photo). After making a large "X" cut with an Exacto knife, I used a six inch screwdriver to poke a hole in the inside seal, then stuck a wire coat hanger through to attach both the air lines and power wire. Pulling the coat hanger back out brought everything through the plug as planned.When comparing the kit to the Firestone product, I rate equal with less cost. Perhaps Firestone is charging more for the name. I don't know. And a side note here: someone complained about the rubber smell of the air emptying into the cab when you deflate or adjust the bags. If this is serious problem for you, don't buy the Firestone system either because it works the exact same way. To me, it isn't an issue.This is not a difficult installation if you have the proper tools, experience using them, and can follow instructions. If any of those three things are a problem for you, I strongly recommend having the job done by someone else.

I’ve used the Airlift Load Controller before on earlier trucks. It makes ride control of your air bags very easy. However, the system is not easy to install when routing wire and air hose through your firewall. Consider spending a little more and getting the wireless model. Or, skip the DIY headache and have it professionally installed.

I know this isn't airlift's fault and this isn't a knock on their products but half of the kit was missing. All I received was a wire harness and a gauge. No compressor, no air lines and no fittings.**Edit**After returning incomplete kit I ordered a new one with any issues. Installed in a few hours without any leaks on the first try. Install was easy and dorections were straightforward. Great system so far.

I bought this because I tow my RV a lot with my 2018 F-150. It sags in the back once I got everything loaded in the bed of my truck. I have an equalizer hitch but it still squats from the truck bed weight. Installation was easy and straight forward. The directions are good. When installing the air lines in the push connectors I push them all the way in then twist them both ways to help seat them to insure no leaks and I had no leaks. There is plenty of air line. I would pick up some extra #12 electrical cord/wire, I needed it, about 6 to 7 feet. I also need a fuse holder. The kit 25854 did not have one, it had the fuse but no holder. I installed in the gauge and controller in the dash because I wanted a factory look. I installed the gauge were the four wheel drive selector would go, I have 2 wheel drive. I had a coin holder there so converted it to hold my air lift gauge controller.I like the analog system because there is no interference in the signal. With wireless systems I saw reviews with to many problems. With an analog system is fully enclose and those wireless problems will not be there so it is more reliable.I highly recommend this system. I have the Air Bag 59570 rated for 2000lbs . I tow 4400lbs with a truck bed weight of about 400 to 500lbs. The ride when empty is great even better than stock, I keep the air bags about 10 psi. I have not towed with this set up yet going on a 1000 mile trip next month I will up date.One other thing to air up the system with the a/c on you cannot hear the compressor, with a/c off you can barley hear the compressor. It is a very quiet system.
