How to Install the Air Lift Air Helper Springs on a 2011 Chevrolet Avalanche


Today in this 2011 Chevrolet Avalanche, were going to install part number AL60769. This is the Air Lift 1000 Air Helper Springs for coil springs. Before we begin our install, well take some measurements and run a few tests on our vehicle with the factory bump stops on it. First, well measure from the top of the wheel down to the ground with no load on it. This will be your normal ride height. In this case, 38 inches. Then, well go ahead and put in about 1,000 pounds worth of weight in the back.

Well go ahead and get another measurement and were down 36 inches. Now, well run through a solemn course and bump course to show you how a vehicle handles. Next, with the Air Lift Helper Springs installed, well go ahead and make sure that we have 35 PSI in our air springs. Then, well go ahead and put our load back in the truck and take some measurements. Okay, now with our load in place, looks like we we're down to about 37 inches. Lets go and take it for a test drive and see how it does. Well now run it through our test course again to show you the difference.

Now, well go ahead and get your truck ready to install our Air Lift kit. Well go ahead and remove the spare tire to give us some extra working room underneath. Next, well go ahead and remove the heat shield for the spare tire. We use a 15 millimeter socket to do that. This will be reinstalled on the last steps. Now, the next thing we want to do is go ahead and take the weight off the suspension.

Basically, youre going to have to lift it up by the frame and let the suspension hang down. We have a special apparatus but you could also use some jacks at the end of the frame as well to push up the vehicle. Now to start off, were actually going to work for our air line tubing first for a little bit. Now, were going to run through the hole in this rubber cap thats on top of the spring here. Were going to pull it out through the bottom of all the springs. Lets get through the section where we can work with it.

Next, were going to put in our spacer right here. Its going to go all the way to the very top and fit up against that rubber stop. Now, its not going to hold itself up there. Im just going to shove it off to the side for now and lets go ahead work with our air bag. Now, were going to make our air spring here as flat as possible so well take the cap off and well go ahead and compress it down and make it the smallest possible. Then, well put the cap back on. Then, well take it and well fold it and work inside the spring with this going towards the top. Were going to fold it up. Now, well go ahead and put a zip tie around it to help hold its shape while we put it in there. Now, lets go ahead and just work our air spring in. Well go ahead and get ready to make our connection from our air line to our air spring. Theres a small clamp that comes with the kit. Now, well just slide it over the hose for now. Then, were going to take the cap off the stem. We still got our zip ties holding it together and see if its working okay. Well take the air line and well just go ahead and push it over the stem and onto it is just a barbed fitting. Well work it down as far as it can go and then put our clamp into place. Were going to have to use some pliers in the last little bit there. Lets go ahead and run our spacer over the top of it. It will just take up all our slack basically. Well go ahead and put it into place. Then, well go ahead and cut off our zip ties. Double check over the top. Make sure its not kinked or anything. We can go ahead and take our air line and run it towards our bumper. Were going to take ours and just run it over the top of the frame and the cross members of the frame. Leave a little bit loose something here and keep going towards the back. Once we get back to the bumper, well go ahead and leave a coil in it in case if youll make any other adjustments. Eventually, were going to be coming out by our electrical connector here. Leave enough coil on this one and well go ahead and cut off. Now, were using a tubing cutter to make sure the cut is straight. You could use a knife as well but this works really good. You want a nice even cut like that. For now, were done for drivers side. Lets go ahead and repeat the same process over on the passengers side. Now, on this side, were going to try a little trick. Were going to try something different. Were going to put our air line on first here and then work it in place. Lets go ahead and work this into place. One last check to make sure that our air line is straight as possible and then well go ahead and run our air line to the front like we did last time. Lets go ahead and follow the frame back along with the factory wiring and well just route it to our same spot as we did before. Lets leave those guys alone for now. Next, were going to go ahead and find a place for our air line fitting. Installing our valve is going to be a matter of personal preference. In this place, the customers kind enough to go ahead and mark it with some blue tape to let us know where our location is. Were going to drill this out with a 5/16 drill bit. Next, well go ahead install our hardware for our air valve. First, nut in the back. Well run it practically almost all the way down the threads and then a lock washer. Then, well go ahead and route this through the hole. On this side, a rubber washer, a flat washer and another nut. Well run those down finger tight and then tighten it up with a half inch socket. You dont have to crush it, just up to that everythings snug. Lets go ahead and take one of our air lines. It doesnt really matter which one. Were going to put a clamp on it just like we did the air springs. Push it in the back of our air valve. Just put a clamp in place. Well follow that same line up just a little bit and well go ahead and cut it again. Were going to install a T. Were going to clamp on there. Go ahead and put our T into place. Now, the other half of our cut line, well go ahead and do the same thing here. This will be a naturally tight fit, tighter than the air lines going to air springs so a little bit of a spray lubricant will help. Once we cover up the barbs, we can go ahead and put our clamp into place. Well go ahead and take our last line from the passengers side. Well go ahead and put it on the last part of the T. Now, lets go ahead and just zip tie our lines. Make sure its safe and secure and out of the way. We got everything connected. Lets go ahead and inflate the bags initially to make sure it fit okay. Well go ahead and add our air a little bit trying to make sure our bag fit okay. Were going to a maximum PSI about 35 pounds. Lets go ahead and check for leaks. Were going to use some soapy water and a spray bottle. Well spray it on all our connections to look for big bubbles. Were done for leak test. Well go ahead and install our last component. This will be the heat shield that will go between the exhaust and the air spring. Well have to bend these tabs out into a L-shape so we can clamp it to our exhaust. It is up against our exhaust about like this and then the kit comes to hold clamps clamp it to exhaust. Lets go ahead and put our clamps on first. Lets take our T-hose clamps and run it back together. Then, well get it started. Do the other one. You just need a 5/16 socket to tighten this down. Now, our clamp will go over the tabs right here that we made. Well just go ahead and rotate it towards our air bag. Well go ahead and tighten it down. Now, theres a lot of excess in our clamp. You can leave it just like it is. Its not going to hurt anything but I think I might shorten it just a little bit. This leaves a really sharp edge so Ill take some needle nose pliers and just twist them around to fold it over itself. Now, at this point, we can go ahead and reinstall our heat shield for our spare tire and the spare tire. With that, that will finish it for the Air Lift 1000 Air Helper Springs on our 2011 Chevrolet Avalanche, part number AL6079. .
