How to Install the Air Life LoadLifter Air Helper Springs on a 2013 GMC Sierra

Today on our 2013 GMC Sierra, well be installing the Air Lift Vehicle Suspension System, part number AL57338. This will be the rear airbag setup for our vehicle. To begin our install, well first need to remove a few of the manufacturers components, starting with the jounce bumper. To remove the jounce bumper, well just take a flat blade screwdriver, get in between the jounce bumper cup and the jounce bumper itself, and pry it out of the cup. Next, on both sides, well remove the bolt that secures the rear brake line to the back of the jounce bump stop. Also here on the drivers side, well need to remove the bolt and bracket that secures the parking brake cable. Well remove the bolt from the frame and then remove the bracket off the cable, and we will relocate it once we complete installing the airbag.

Now, Ill move over to the passengers side. Well also need to remove the parking brake cable bracket that runs to the front of the jounce stop bracket.Now with our hardware set aside, were ready to go ahead and start assembling our new airbag suspension system. Starting with the airbag, well take the top and bottom cups and set them over the airbag ends and securing points. Then, well take the right angle valve supplied with our install kit that youll notice has preinstalled thread sealer and secure it into the top of the airbag. Once we have the angle valve in place, we can go ahead and install our top mount, using the cap-headed screws provided with the install kit. Now, well go ahead and turn our airbag over; install the lower bracket.

With our suspension spread as much as possible between the axle and the frame, were now ready to go ahead and put our airbag assembly into position, fitting the lower bracket over the jounce stop bracket, and the upper bracket will go around the jounce stop cup. Once we get it into position, we can go ahead and use the 2 3/8 fasteners to secure the lower bracket into place. These will simply pinch the lower bracket against the stop. Well go ahead and take the U-bolt, put it over the frame, and down through the upper bracket. There, well secure it with a flat washers and nylon locknut. Now, well go ahead and repeat the same process for our other attachment point.

Now with the upper bracket secured, well move to the lower bracket. Well need to install the carriage bolts that will go down through the lower bracket and secure the lower barrel clamp. To secure the carriage bolt and lower barrel clamp, well use the flat washer and nylon locknut. Now that weve secured the lower bracket, well go ahead and reinstall the manufacturers hardware, re-securing the brake line bracket. Note: the parking brake cable on the drivers side will then get zip tied to the upper bracket for the airbag suspension system. Well cut off the excess in the zip tie to clean up our install look. Now, once we have both sides installed, well need to install the heat shield for the passengers side.

The heat shield will be secured to the tailpipe using the 2 bands clamps provided with the install kit. Then well go ahead and bend the tabs in the heat shield so that we can slide them under the clamps and then secure the clamps, securing the heat shield into position. Now, with that done, were ready to run the air line for the airbags. Note: well be using our Tow Ready No Drill Mounting Bracket, part number 18140, and drilling it out as needed to secure the air line fittings to the hitch. To secure the bracket to the hitch, well go ahead and turn that bracket vertically on the back side of the hitch and then secure it with the worm clamp. Now, with the bracket secured, well go ahead and drill it out as per the instructions. It will be large enough to fit the air line inflation valve. Once its drilled out, well go ahead and take the air line and start working from the bag towards the back of the vehicle where well mount the line. Well take one end, feed it along the frame following the manufacturers wiring, and then down to our bracket. Once we get to the bracket, well install the nut-serrated washer and then put it through the bracket. Next, well install the rubber washer, flat washer, and then secure it with the file nut and tighten it down. Now, well go back to the bag in the air line, run the air line to the 90 degree valve that we installed in the top of the airbag, make a mark in our line, and then go ahead and cut the line with our tubing cutter. Once we cut our line to fit, well line it up with the orange section of the 90 degree valve, push in firmly, and then give it a quick tug to seed it into position. Now, well go ahead and repeat the same process in the passengers side.Next, with all our components installed, well go ahead and check our air lines for leaks. Well install air into the air lines. Well bring them up to approximately 50 psi. Then well go ahead and squirt each one of the air line connection points with some soapy water and check for a leak.Heres what our vehicle looks like at the manufacturers suspension and vehicle height. Then, well add 2,000 pounds, noticing how the rear end will begin to sag with the additional weight. Now, with our airbag system installed, we will add air in the airbags and reinstall the weight. As you can see, with our airbags installed, we will not lose the right height that we did previously with our manufacturers suspension system.With that, were ready to hit the road, and that does it for the install of the Air Lift Vehicle Suspension System, part number AL57338 in our 2013 GMC Sierra. .
