Low air pressure is the chief reason for air spring failure. To avoid this, you have to either regularly monitor your air springs or find a device that will do it for you. Air Lift's Load Controller II air control system for light-to-medium-duty vehicles does just that. If the air pressure in your air springs falls below the minimum level, the system's low-pressure sensor detects the decrease in air pressure. Then the system activates automatically to adjust air pressure as needed.
Load Controller II has virtually vibration-free operation and is made to help support your air springs as they take on weighty loads. The single-path controller lets you adjust one pair of air springs, so you can maintain equal air pressure in both springs for simple front-to-back leveling. A gauge provides detailed monitoring of your air pressure.
Air Lift kits are designed to keep your vehicle at normal ride height. You can find the normal ride height of your vehicle by unloading it and measuring the distance between the bottom edge of your wheel well and the center of the hub. After you find and record this distance, you can regulate the amount of air that you send to your air springs to maintain normal ride height - even when you are hauling a heavy load. You will need to adjust the air pressure in your air bags according to the size of your load.

Today on this 2006 Ford F150, we're going to install part number AL25592. This is the Air Lift Load Controller II Compressor system. Before we show you how it installs we'll show you what it does and how it works. Now the pressure sensor will always maintain a minimum PSI and the airbags help keep their shape so every time we turn on the ignition it'll check for that and it'll inflate the bags as needed. We'll go ahead add more pressure to it. We'll go ahead and press on the rocker switch and you can see how the air bags will kick on and the air gauge goes up.
The silver button below the rocker switch lets out the air. Let's go ahead and try it out. We'll go ahead and put a load in the back of our truck, and you can see how it sags down. We'll go ahead and use our airbag system to level it out. We ran our PSI to about sixty pounds and brought our truck back to level. All right, let's go ahead and take it for a test drive and see how it feels.
Now we'll show you how it installs. A few notes before we begin, our truck already had a set of airbags installed on it. We're going to upgrade these airbags, also from Air Lift, to work with our load controller. Our first step is to go ahead and find a place for our air gauge. Under our dashboard towards the right-hand side and next to the diagnostic port is a small piece of metal we can use to attach it to.
Now, the bracket for the air gauge has a hole in each side but the metal doesn't go all the way across. We're going to drill an extra hole about a half inch away from the hole on the left-hand side so we have two screws holding it to the metal. We'll go ahead and drill it out with a three-sixteenths drill bit and we're going to go ahead and set it aside for now. Next we'll go ahead and find a place for our compressor unit. We're going to install ours on the driver's side frame rail underneath the truck, just behind the transmission. We'll go ahead and hold it in place and go ahead and mark for our holes.
We're going to take one of the self-tapping screws that comes with the kit and use it to mark our first hole. We'll take the compressor down and we'll go ahead and drill it out. After our hole's drilled out we'll go ahead and remove the screw and re-install the compressor. That'll help hold it up while we install the rest of our fasteners. With all four screws installed that'll finish it for mounting up our compressor. Now we can go back up to our air gauge and install the wiring harness labeled number one in the instructions. This will be the wire harness with the low pressure sensor gauge attached to it already. The end we're going to hook up will be our black line with the two spade connectors. We'll go ahead and push our air line onto the remaining part of the T that's behind the air gauge. Then we'll go ahead and connect our other two spade terminals. They'll go behind the rocker switch. The spade terminal with two wires will go in the center pin, and the spade terminal with the single wire will go to the remaining pin behind the rocker switch. Next we'll go ahead and work with harness number two. We'll go ahead and attach that to our air compressor underneath. This end will have an air line as well with a T connected to it and also a short piece of air line that will go into the barb fitting on the end of the air compressor. It'll have a lone red wire with a spade terminal. We'll connect that red wire with the red wire from the compressor. We'll push those two together and seal them up with some electric tape. Then we'll take our black wire from the compressor and run that straight to ground. We'll use an extra self-tapping screw to accomplish this. Now we'll take the other end of harness number two and we have to run that to the inside. There's a grommet on the driver's side door at the very bottom. We'll go ahead and use a knife to cut through the grommet to make a slit and then we'll go ahead and run the other half of our wire harness through the slit and in as far as we can. Next we'll go inside the truck and we'll go ahead and remove the threshold. It simply pops off. We'll pull back the carpet and look for our air line that we ran through. We'll go ahead and pull it out along with the red wire. We'll go ahead and pull up enough of the air line and the wire to meet up with our first harness. We'll pull up a little bit more than we need and we can always return the rest of our line back underneath. We'll go ahead and hook up our number two harness to our first harness. We'll go ahead and take our black air line and run it into the T for our pressure switch. All we have to do is push it in and give it a small tug back to lock it into place. We'll take our red wire and go ahead and connect it to the spade terminal on our pressure switch. With everything connected we'll go ahead and leave it alone for now. Now we'll go ahead and work on our air line going back to our airbags. Going back to our air compressor we'll go ahead and take the extra length of line and go ahead and connect it to the T. We'll route that along underneath the body of the truck and out to the driver's side frame rail on our way back to the back axle and the airbags. We'll go ahead and run our line past our airbag and where we need it we'll go ahead and cut it and connect that to the center section of our T, and then we'll connect our air line from our air compressor to one of the sides of the T. We'll also take some of the excess and use a small piece of line, we'll go ahead and put it into the T and connect that directly to the airbag. Now with our third leg of our T we need to run that to the other side. We'll go ahead and reuse some of the air line from the airbags that we're originally installed. We'll go ahead and put it into the T, run it across, and go directly into the other airbag. Next we'll go ahead and turn our attention to the power wire. This is located on harness number one. This will be a red wire with a fuse holder attached to it and a spade terminal. We need to take this wire and run it over to the passenger side over to the fuse box. Now we run our wire to the fuse panel, we're going to go behind the console, we're actually going to use another piece of old air line tubing to help pull it through. We're actually going to pull our wire through one of the vents that goes to the other side. Also, we found out that our wire's going to be a little bit short. We'll cut off towards the end then we'll go ahead and section in a length of wire. Our kit does come with some extra lengths of wire so we'll use it to go ahead and extend the length. We'll add our butt connectors that come with the kit to our section of wire, and then we'll go ahead and connect it to our original wire that way we can reuse our spade connector already on the end of our wire. Now this red wire will use power from the fuse box so we need to use a fuse that only gets power when the key is turned on. This will vary between vehicles and trim packages. In this case we used a fuse that was labeled for power for the audio, power door lock switch, and moon roof switch illumination. We'll go ahead and test it to make sure it works, that it does not have power when the key is off and it does have power when the key is turned on. Once we're satisfied with the one we want we'll go ahead and remove the fuse. We'll have to look for the side of the fuse that gets power. We'll go ahead and probe the socket and look for which one gets power first. Once we know that we can go ahead and connect our wire to that side of the fuse. We'll take a fuse cap with a small brass fitting that'll fit over the end of the fuse. It just wraps around the leg and snaps over the top. Then we'll take our power wire and attach it to the spade connector on top. Then we can go ahead and re-install the fuse. Now with our extra wire coming out from the fuse we're going to have to make a notch in the box so we have room to run our wire to the outside. We're going to use a rotary tool to make a small notch to put our wire into. Then we can go ahead and re-install the cover. With the cover back in place we'll go ahead and tuck the wire behind the carpeting, or, if you'd like, you can also zip tie it to some wiring just below the edge of the dashboard on the passenger side. All right, now we need to get some wires ran for our gauge light. Using the remaining length of wire that came with our kit, our red and our black wire, we'll go ahead and add two spade terminals to each end. These two spade terminals will connect to the back side of the air gauge. This will be for illumination. Then we'll go ahead and run our power for illumination. What we're going to do is run it to the back side of the switch on the dashboard. We can go ahead and just remove the panel itself and the whole switch comes out with it. We'll go ahead and probe our wire to see if it gets power when we turn on the lights. In this case it was a white wire with a red stripe. We run our wire to the switch and we're going to go behind the console. We'll use this quick splice connector to attach our red wire to that wire. We simply take our quick splice connector and connect it to our illumination wire and then we'll take our red wire and slide it in next to it. We'll make sure it goes in all the way until it bottoms out, then we'll go ahead and use a pair of pliers to squeeze it together to make our electrical connection. We'll go ahead and snap the cover back on it and we can go ahead and re-install the switch. Now our black wire we need to run directly to ground so we'll go ahead and go back towards the bottom of the dash, and using the provided ring terminal we'll attach that to the wire and then we'll use an extra self-tapping screw to run that through the sheet metal at the bottom of the dashboard. Okay, with this all our electrical connections are made. Now we'll install our gauge using the hardware provided. Now we'll tuck our wires underneath the carpet and re-install the threshold. We'll go ahead and take our wires and air lines and zip tie them out of the way to make sure everything is safe and secure and won't interfere with the pedals. Then we'll go underneath the truck and go ahead and make sure our lines going to our air compressor are all secure as well. Okay, with that that'll finish it for our install of part number AL25592 from Air Lift on our 2006 Ford F150. .

I first realized that I needed some help leveling my 2006 Yukon XL right after I hooked my 2 place trailer to the vechile. My previous Yukon had self leveling rear shocks, the 2006 did not come w/ that option. I mounted the compressor on the top of the passenger side wheel well, (there is plenty of room there, & away from engine heat) I mounted the pump & dump switchs , & the pressure gage on a piece of kydex that I cut to fit in the little cubby that is below the heat/ac controls. The hardest part was getting the lift "bags" into the coil spring tower, time & patience. The install looks factory, & works great to level the vechile while towing. Great product! 476879
I've had this for about a year so far, I mounted it underneath the passenger rear door (outside) of my Dodge 3500 to run the air bags. I haven't had any problems at all. Great Product. FYI found out later the have a wireless one.. would have spent a lot less time installing. oh well 376773
. Box came looking like it was ran through a mine fiend though. Everything inside looks in ok but will find out when I install it this weekend. But definitely will buy again from etrailer nothing but great reviews for them. usps who had package transferred to not so much. Know it wasn't ups cause never had one look like this from them 337374
Great product easy installation works great on my Silverado!! 797599
The air suspension bolted into place with no issues ... perfect fit. The hardware for the air pump and gauge was complete. Had the job done in a day. 398914
Installation of the Airlift air helper springs and air compressor was easy ,had 1200 lbs. in the bed of my truck and could"nt be more pleased with the load leveling and the ride , can"t wait to hook up my 5th wheel to see how it rides,very good product highly recommended . 389731
Good value did everything I wanted it to Compressor is a lil noisy good thing it doesn't run much 299936
I will say excellent but truthfully I just installed today. Will know more after a trip or two. Works as it should. Had plenty of everything I needed. Only thing I did not like was lack of a relay. I personally don't like pulling 15 amps off of my fuse panel. I used the supplied wire as a signal for a 30 amp relay and pulled it from a lug near the battery. Maybe not necessary but made me feel better. The compressor is noisy. Would have installed under a seat bit did not like the noise. Found a place that should keep it out of water splashing from tires. We'll see. Only problem was the pressure switch was supposed to be set at five pounds. More like one. Easy to fix. 261607
Works as it should. 235464
Tom P - 01/15/2017KYB shocks and struts for my 05 Pilot EX, along with the air ride load leveler pillows were here within a week of ordering at a great price! Happy with front end of my purchase, now for the install! Kudos to etrailer.com! 151316
Item arrived on time. Instructions were clear and simple. Was supplied with all necessary hardware. Very satisfied. 122963
The install was very straight forward and the instructions were great. I had more than enough air line for an extended cab short box chevy. I would buy this again in a heartbeat. It has no problems supplying enough air to the air bags and it does it quickly and quietly. 65154
Great product, finding wiring to connect to on newer trucks is a little tough though. 62051
