I. MountingtheCompressor
1. Select a rigid convenient mounting location on the frame or in a
storage area. The location selected should shield the
compressor from the elements.
IMPORTANT: Be careful to
shield the compressor from heat sources. Do not mount the
compressor in the engine compartment. Doing so can cause
prematurefailuretothe compressor
2. Using the mounting holes on the compressor legs as a guide,
mark the mounting hole locations.
3. Remove the compressor and center punch and drill four 13/64"
diameter holes.
4. Use the supplied screws and nuts to mount the compressor
(Figure2).
5. Attachtheair filterto theinlet port at thebackof thecompressor
(Figure3).
6. Install the fitting into the pressure port side of the leader hose
(Figure4).
II.MountingtheDashPanel
1. Select a convenient, sturdy mounting location for the gauge
panel.
2. Usingthe gaugepanel mountingbracket asa template, position
the gauge panel to the mounting surface.
3. Secure with two self-tapping screws.
III. WiringtheElectricalConnections
1. Install the yellow ring terminal to the compressor motor ground
(black) wire. Select a good ground location, and attach the ring
terminal with the self-tapping screw provided.
2. Determine the length of supplied (red) wire required to connect
the dash panel to the compressor.
3. Connect the (red) wire from the panel to the (red) wire on the
compressor using a blue butt connector (Figure 1).Connect the
otherend ofthewire tothepush switch usingtheblue3/16 female
push on connector. With your thumb against the front side of
the switch, push the connector onto one of the terminals on the
back of the ON/OFF switch on the gauge panel

If the vehicle uses the barrel type fuse, use adapter #1. If the
vehicle uses the standard spade type fuses, use adapter #2.
Many late model vehicles use a smaller spade type fuse which
requires adapter #3. See Inset A on the first page.
5. Determine the length of supplied (red) wire required to connect
the dash panel to the fuse assembly. Cut and crimp the wire
into the butt connector (Figure 1).Connect the other end of the
wire to the push switch using the blue 3/16" female push on
connector. With your thumb against the front side of the switch,
push the connector onto the remaining terminal on the back of
the ON/OFF switch on the gauge panel.
6. Route the white wire for the illuminated gauge to an accessory
power source. Attach the black wire to an adequate ground.
IV.Installingthe AirLine
1. Remove the air pressure from the air springs by taking the core
out of the inflation valve, or by using a tire gauge to depress the
core to bleed off the air pressure.
2. Use a standard tube cutter, a razor blade, or very sharp knife to
cut the air line between the air spring and the inflation valve. A
cleansquare cutwill ensureagainst leaks. Install atee. Repeat
this step for other side (Figure 5).
3. Route air line between the two tees and connect to the last
opening in each tee.
NOTE: Keep air line away from heat
(exhaustsystem,etc.) andmovingchassiscomponents. Secure
air line to the frame with nylon tie straps provided.
4. Determine the location of the third tee. Cut the air line between
the first two tees and install a third (Figures 1 & 5).
5. Measure the distance from the open tee to the compressor.Cut
Cut off excess air line squarely. Install the air line into
the fitting. This is a self–locking fitting. Push and
slightly turn the cut end of the air line into the fitting as
far as it will go. You will hear or feel a definite click
when the air line is seated. Air line should go in 9/16".
The air line is now installed.

6. Install the air line into the air line fitting previously installed on the compressor (Figure 4).
7. Determine the closest and easiest area to connect the gauge panel to the air line between the compressor and air
springs. Measurethe distancebetween thesetwopoints andcut theairline andinstall the lasttee (Figures1 &5).
8. Attach air line to the last leg of this tee and route the air line to the gauge panel. Attach the air line to the panel
sliding it onto the barbed fitting on the panel until it fully covers all the barbs.
9. Turn on ignition switch. Push on/off switch and observe pressure increase on the air gauge (Figure 6). Inflate to
maximumrecommended pressure.Inspect each connectionwith asoapand watersolution. If a leakis foundinthe
fittings, reduce air pressure to zero and tighten threaded connections or remove air line, cut off one inch and
reattach.

V. InflationControl
1. Your vehicle is equipped with rear air springs. The following procedure is a “guide” to assist you in leveling your
vehicle to provide the best possible ride and handling.
2. Fill the air springs to maximum recommended pressure.The pressure can be increased from the dash control or
the inflation valves located just ahead of the rear wheels. Generally, the vehicle will ride best when the rear springs
areslightly arched (ifequippedwith leafsprings). Start withahigher pressureand decreaseinfivepoundincrements
todetermine thebest rideandhandling foryourparticularvehicle. Increasesin pressurecanbemade tocompensate
for additional load and trailers, etc. Higher pressures can be used when the vehicle is in storage to relieve the leaf
springs.
VI. OperatingInstructions
1. IMPORTANT: Donot exceedthe recommended dutycycle of 15%(3 minuteson and20minutes off). Notcomplying
with the recommended duty cycle may cause premature failure of the compressor.
2. The air springs should be inflated to the specified air pressure as discussed in the air spring inflation procedure.
3. When ever load and weight distribution change, simply adjust the pressure in the air springs to maintain a level
vehicle.The air pressure is manually controlled by the control panel located on the dash.
4. To inflate the air springs and raise the vehicle, depress the switch on the control panel.The compressor will turn on
automaticallyto increasethe pressureasindicated onthe gauge. Oncethedesired pressureisreached, release the
switch and the compressor will shut-off.
5. To deflate the air springs, depress the button below the on/off switch (Figure 6).
VII. Troubleshooting
1. Intheevent thatthecompressor stopsrunning,allow thecompressor tocool down beforerunning again andprovide
adequate time for the thermal breaker to reset before trying to start the compressor again.
2. Check theinflation pressure weekly, airspring bellowswill permeate (lossofpressure throughtherubber wall) atthe
approximate rate of 3–4 p.s.i. per week. Leakage at a higher rate indicates a leak. In order to find a possible leak,
inflate the system to the maximum recommended pressure and spray all fittings with soapy water solution.
a. Check the inflation valve, including the valve core and air line connections.
b. Check the elbow fitting where threaded into the bellows (all threaded connections must have pipe sealant
applied) and the air line connection.
CAUTION: Do not exceed the recommended duty cycle of 15% (3 minutes on, 20 minutes off). Not
complying with the recommended duty cycle may cause premature failure of the compressor.
CAUTION: Do not exceed the vehicle manufacturers maximum gross vehicle weight rating (GVWR).

Frequently asked questions
Q. Will installing air springs increase the weight ratings of a vehicle?
No. Adding air springs will not change the weight ratings (GAWR, GCWR and/or GVWR) of a vehicle. Exceeding the
GVWR is dangerous and voids the Air Lift warranty.
Q. Is it necessary to keep air in the air springs at all time and how much pressure will they need?
The minimum air pressure should be maintained at all times. The minimum air pressure keeps the air spring in shape,
ensuring that it will move throughout its travel without rubbing or wearing on itself.
Q. Is it necessary to add a compressor system to the air springs?
No.Airpressurecanbeadjustedwithanytypeofcompressoraslongasitcanproducesufcientpressuretoservice
the springs. Even a bicycle tire pump can be used, but it’s a lot of work.
Q. How long should air springs last?
Iftheairspringsareproperlyinstalledandmaintainedtheycanlastindenitely.
Q. Will raising the vehicle on a hoist for service work damage the air springs?
No. The vehicle can be lifted on a hoist for short-term service work such as tire rotation or oil changes. However, if
the vehicle will be on the hoist for a prolonged period of time, support the axle with jack stands in order to take the
tension off of the air springs.
Tuning the air pressure
Pressure determination comes down to three things — level vehicle, ride comfort, and stability.
1. Level vehicle

Raise the air pressure to correct either of these problems and level the vehicle.
2. Ride comfort
