Today in our 2012 Ford F-150, we're going to review an install of the Air Lift Vehicle Suspension LoadLifter 5000 Ultimate Air Helper Springs, part number AL88200. Here's what our air bag assemblies will look like once they're installed. The LoadLifter 5000s are capable up to 5,000 pounds and can be aired up from 5 psi to 100 psi. This is a really nice system, works well with the vehicle's current frame and suspension system with minimum modifications. This is a perfect add-on system to help carry heavy loads, keep the vehicle from squatting and wearing out the rear suspension. While it's not required, it can make it easier and give you more working room underneath if you go ahead and lower and remove the spare tire, as we've done here. To begin our install, we're going to go ahead and remove the manufacturer's jounce bumper. The jounce bumper is secured to the frame with a bolt up through the center. Once we have the jounce bumper out, we'll go ahead and set it aside, as it will not be reinstalled.
The jounce bumper fastener went up into a well nut in the frame. Some applications will not have a well nut; it will be more of a clip nut into an open hole. In those cases, you'll replace the clip nut. Next, on the passenger side only, we have the emergency cable bracket that comes down and bolts to a bracket that's secured directly to the axle. This bolt will need to be trimmed off, flush with the bracket, in order to allow for our fastener here on the passenger's side. To cut this off, you could use a hacksaw, sawzall, or we're going to use a cut-off wheel. All right.
Now we've got our vehicle prepped. We're going to start prepping our air bag. We'll have a roll plated that goes on top and bottom of our air bag. The roll plate has pre-drilled holes to line up with the threaded fittings in the air bag. Here's our bottom plate and our top.
Note that the roll plate cups over the air bag. Next we'll go ahead and install our air fitting. The air fitting already has a pre-installed sealant on the threads, so let me go ahead and put it right into the air bag. First we'll install it finger-tight and then we'll give it an additional 1.5 turns, being careful not to over-tighten it. Next we'll install the first of two upper plates. Here in the plate is inscribed an L. That will be for the left or driver's side.
Once we get our top plate in position, we'll make sure we line up our attachment points and use the two cap-headed bolts to secure it. I'm just going to get them started by hand and run them down. Now that we've got them tightened down, I'm going to go ahead and torque to specifications. Next we'll install the second piece of our upper bracket. It too is marked L for the driver's side, or left side. It ultimately attaches the two top plates together using a carriage bolt. It will come from the bottom top plate, then a flat washer and nut. Before we attach those two together, though, we need to secure this to the frame. We'll use the cap-headed bolt and a flat washer to go through the attachment point and into the old jounce stop fastener. Then we'll bring in our air bag and secure it with the carriage bolt. Now as we put our upper bracket to the frame, we'll notice that the bent tab will go on the outside of the frame, lining up the attachment point with the well nut where we removed the old or manufacturer's jounce bumper and install our bolt and flat washer. I'll go ahead and tighten it down and then torque to specifications as indicated in the instructions. Once our plate is secured to the frame, we'll go ahead and bring in our assembled top plate and air bag and install the fasteners. Once we have them in place, we'll go ahead and tighten them down and torque to specifications. We're now ready to install the lower bracket. Our lower bracket will slide in between our air bag and the axle. Note, make sure that the outside portion here that faces the leaf spring pack sits between the two U-bolts. Once we have it in place, we'll install the support bracket that slides onto the pre-installed studs. Once we have the support bracket in place, we'll install a flat washer and lock nut for each. Once I have these fasteners in place I'm going to go ahead and tighten them down. Now I'll go ahead and torque to specifications. Next we need to install our carriage bolts. The carriage bolts will be installed to secure the lower bracket to the axle or axle straps. There are a total of six square holes that our carriage bolts will fit into. We want to make sure we're using the inside square holes. Quick tech tip: to make sure you have the lower bracket in the correct position, it is
