AccuAir Stage II Air Management System Install - Accuair Computerized Air Ride

To ensure the DIY guy at home stands a real good chance of performing a trouble-free installation without leaks, AccuAir also supplies a handy tubing cutter so all of the air line ends will be perfectly square and free from burrs.

AccuAir includes a heavy-duty 90-amp relay (solenoid) that turns both of the compressors on. The rest of the wiring was cleanly routed on the underside of the frame.

The tank pressure sensor shown on the left side of the rear tank replaces the typical mechanical pressure switch and allows the e-Level system to turn the compressors on and off when necessary. Notice how the plug-n-play connector from the valves to the ECU makes for a super clean and easy installation.

With the installation of the air management system completed, it was time to mount the ride height sensors. The first step in mounting the rear ride height sensors was to find a point on the Ford's four-link rear suspension which has 2 3/4-inches of travel throughout the total range of suspension motion. Dustin traced the angle of the four-link onto a piece of cardboard at the maximum and minimum suspension travel.

With the Low and High positions marked, Dustin measures to find the spot on the arm that travels 2 3/4-inches. The four-link was then drilled and tapped at this spot for the ride height sensor linkage to attach to.

With the rear of the truck completed, it was now time to repeat the process for the front ride height sensors. A transmission jack can be a handy tool for cycling the suspension up and down for the sensor mounting process.

This photo is with the suspension up and with the linkage attached. The sensor was temporarily clamped to the frame while once more cycling the suspension throughout its full travel. With the perfect location determined, the frame was drilled and tapped to mount the sensor permanently. The process was then repeated for the other rear side of the truck.

The crew at AccuAir used a two-piece shaft collar for mounting the ride height sensor linkage to the front tubular control arms.

The steps described above should be repeated exactly, except now the suspension must be down in its travel (position).

Suspension down: As with the rear end the guys found the point on the control arm moved 2 3/4- inches throughout its complete travel. In this case, they found that it was best to use a spot that only moves about 2 inches due to the location of the shock absorbers. Dustin and Reno mentioned they have run all the way down to 1-inch of travel on the sensor in previous installations and maintained perfect accuracy.

Suspension up: Same scenario as the previous caption, but now the suspension is up.

Same thing as previously, but this is a view of the right (passenger) side.
