GETTING STARTED
1. Jack up the rear of the vehicle or raise on a hoist. Support the frame with safety stands
(Fig. 1).
2. Lower the axle or raise the body of the vehicle until the springs are completely extended
(wheels hanging).
OBSERVE TENSION ON BRAKE LINE. DO NOT STRAIN.
3. Remove the plastic cap from the barbed stem on the end of the air spring. Exhaust the
air from the air spring by rolling it up toward the barbed stem. Replace the cap on the
stem to hold the at shape (Fig. 2). Fold air spring into a “hot dog bun” shape.

4. Insert the attened air spring into the coil spring through the lowest opening with the
stem at the top (Fig. 3).
5. Push the air spring up within the coil by hand or with a blunt instrument such as a spoon-
type tire iron.
6. When the air spring is completely within the coil, remove the cap and allow the air spring
to assume its “as molded” shape. Push the cylinder down to the bottom of the spring so
that the stem at the top can be accessed for attaching the hose.
7. Route the hose down from the outside of the frame, through the hole in the top spring
seat (Fig. 4). Insert hose through the protector and attach to the cylinder per the next
section.
INSTALLING THE AIR LINE
A tee air line installation is recommended unless the weight in the vehicle varies from one
side to the other and unequal pressures are needed to level the load or compensate for axle
torque transfer in racing applications. Dual air lines are used in this case.
TEE AIR LINE ROUTING
TO PREVENT THE AIR LINE FROM MELTING, MAINTAIN AT LEAST 8” (203.2MM) FROM
THE EXHAUST SYSTEM TO THE AIR LINE.
1. Locate the desired tee location on the frame rail or cross member. Determine and cut
adequate length of air line to reach from tee to the left and right side air springs.
LEAVE SUFFICIENT AIR LINE SLACK TO PREVENT ANY STRAIN ON THE FITTING
DURING AXLE MOTIONS.
2. Slide an air line clamp onto the air line.
3. Push the air line over one side of the tee until all the barbs are covered. With a pair of
pliers, slide the air line clamp forward until it fully covers the barbed section. Repeat
entire procedure for other leg of the tee (Fig. 5).
4. Route the air line along the cross member and either the lower control arm or the upper
spring seat to the air spring.
5. Insert the air line through the spring seat and spacers.

6. Push the air line onto the stem, covering all the barbs (Fig. 6). With the pliers, slide the
air line clamp upward until it fully covers the barbed section.
7. Push the remaining air line over the last tting on the tee and route it along the frame
to the desired ination valve location. Attach the air line with plastic straps or wire.
8. Select a location for the ination valve in the gas cap well, the trunk, rear bumper, fender
ange or behind license plate, insuring that the valve will be protected and accessible
with an air hose (Fig. 7).
9. Drill a 5/16” (8mm) hole for the ination valve and mount as shown (Fig. 8). The rubber
washer serves as an outside weather seal.
10. Slide the air line clamp over the air line. Push the air line onto the tting covering all
barbs. Using pliers, slide the air line clamp forward until it fully covers the barbed section
(Fig. 9).
DO NOT INFLATE AIR SPRINGS BEFORE READING THE MAINTENANCE AND
OPERATION SECTION.

DUAL AIR LINE ROUTING
TO PREVENT AIR LINE FROM MELTING, KEEP IT AT LEAST 8”(203MM) FROM EXHAUST
SYSTEM.
1. Select a location for the ination valves in the rocker panel ange, or rear bumper, assuring
that each valve will be protected and accessible with an air hose.
2. Determine and cut adequate length of air line to reach from valve location to left side air
spring.
LEAVE SUFFICIENT AIR LINE SLACK TO PREVENT ANY STRAIN ON FITTING DURING
AXLE MOTIONS.
3. Insert the air line through the spring seat and spacer.
4. Slide air clamp onto the cut air line.
5. Push the air line onto the stem, covering all the barbed section (see Fig. 6). With pliers
slide the air line clamp forward until it fully covers barbed section.
6. Repeat process for right side.
7. Drill 5/16” (8mm) hole for inating valves and mount as illustrated. Rubber washer is for
outside weather seal (see Fig. 8).
8. Route air line along control arm and frame to ination valve location and cut off excess.
9. Slide a clamp onto the air line and push the air line over the tting, covering all the barbs.
With pliers slide the air line clamp forward until if fully covers the barbed section (see Fig.
9).
10. Raise axle or lower body until air springs lightly touch upper spring seat and lower spacers.
11. Check tail pipe clearance and ensure that it is at least 2-3 inches (50-75mm) from air
springs. If necessary, loosen clamps and rotate or move to obtain additional clearance.
If heat shields are supplied, install them. Attach shock absorbers if removed earlier in
the installation.
DO NOT INFLATE AIR SPRINGS BEFORE READING THE MAINTENANCE AND
OPERATION SECTION.
COMPLETING THE INSTALLATION
1. Once the air line has been installed, raise the suspension or lower the body so that the
air spring just touches the top and the bottom of the upper and lower spring mounts.
The snap together protectors will nest inside of the coil spring upper mount. Inate the air
spring to 35psi (2.4 Bar).
2. Lower the vehicle to the ground. Read the “Maintenance and Servicing” section for proper
care and for setting up the proper pressure in your suspension system.

CHECKING FOR LEAKS
1. Inflate the air spring to 30 PSI (2.1BAR).
2. Spray all connections and the inflation valves with a solution of liquid dish soap and
water. Spot leaks easily by looking for bubbles in the soapy water.
3. After the test, deflate the springs to the minimum pressure required to restore the system
to normal ride height. Do not deflate to lower than 5 PSI (.34BAR).
4. Check the air pressure again after 24 hours. A 2-4 PSI (.14-.3BAR) loss after initial
installation is normal. Retest for leaks if the loss is more than 5 PSI (.34BAR).
FIXING LEAKS
1. If there is a problem with the inflation valve:
a. Check the valve core by tightening it with a valve core tool.
b. Check the air line by removing the air line from the barbed type tting. Cut the air
line off a few inches in front of the tting and use a pair of pliers or vice grips to pull/
twist the air line off of the tting.
DO NOT CUT OFF THE AIR LINE COMPLETELY AS THIS WILL USUALLY NICK THE
BARB AND RENDER THE FITTING USELESS.
2. If the preceding steps have not resolved the problem, call Air Lift customer service at
[phone].
CAUTION

Air Lift 1000
Overnight leak down test — Recheck air pressure after the vehicle has been used for
24 hours. If the pressure has dropped more than 5 PSI (.34BAR), then there is a leak
that must be xed. Either x the leak yourself or return to the installer for service.
Air pressure requirements — Regardless of load, the air pressure should always be
adjusted to maintain ride height at all times.
Thirty day or 500 mile (800km) test —Recheck the air spring system after 30 days or 500
miles (800km), whichever comes first. If any part shows signs of rubbing or abrasion,
the source should be identified and moved, if possible. If it is not possible to relocate
the cause of the abrasion, the air spring may need to be remounted. If professionally
installed, the installer should be consulted. Check all fasteners for tightness.
POST-INSTALLATION CHECKLIST
Clearance test — Inflate the air springs to 30 PSI (2.1BAR) and ensure there is at least
1/2”clearance around each bellow, away from anything that might rub against them.
Be sure to check the tire, brake drum, frame, shock absorbers and brake cables.
Leak test before road test — Inflate the air springs to 30 PSI (2.1BAR), check all
connections for leaks with a soapy water solution. See “Checking for Leaks” on how to
spot leaks. All leaks must be eliminated before the vehicle is road tested.
Heat test — Be sure there is sufficient clearance from any heat sources — at least 6”
(152mm) for air springs and air lines. If a heat shield was included in the kit, install it. If
there is no heat shield, but one is required, call [phone].
Fastener test — Recheck all bolts for proper torque. Re-torque after 100 miles (161 km).
Road test — The vehicle should be road tested after the preceding tests. Inflate the air
springs to 25 PSI/2BAR (30 PSI [2.1BAR] if the vehicle is loaded). Drive the vehicle 10
miles and recheck for clearance, loose fasteners and air leaks.
Operating instructions — If professionally installed, the installer should review the
“Product Use, Maintenance and Servicing” section with the owner. Be sure to provide
the owner with all of the paperwork which came with the kit.

MAINTENANCE GUIDELINES
By following these steps, vehicle owners will obtain the longest life and best results from their
air springs.
1. Check the air pressure weekly.
2. Always maintain normal ride height. Never inate beyond 35 PSI (2.4BAR).
3. If you develop an air leak in the system, use a soapy water solution to check all air line
connections and the ination valve core, before deating and removing the spring.
4. When increasing load, always adjust the air pressure to maintain normal ride height.
Increase or decrease pressure from the system as necessary to attain normal ride height
for optimal ride and handling. Remember that loads carried behind the axle (including
tongue loads) require more leveling force (pressure) than those carried directly over the
axle.
FOR YOUR SAFETY AND TO PREVENT DAMAGE TO YOUR VEHICLE, DO NOT EXCEED
MAXIMUM GROSS VEHICLE WEIGHT RATING (GVWR), AS INDICATED BY THE VEHICLE
MANUFACTURER. ALTHOUGH YOUR AIR SPRINGS ARE RATED AT A MAXIMUM
INFLATION PRESSURE OF 35 PSI (2.4 BAR), THE AIR PRESSURE ACTUALLY NEEDED
IS DEPENDENT ON YOUR LOAD AND GVWR.
5. Always add air to the springs in small quantities, checking the pressure frequently. Cylinders
require less air volume than a tire and inate quickly.
6. Should it become necessary to raise the vehicle by the frame, make sure the system
is at a minimum pressure (5 PSI [.34 Bar]) to reduce tension on the suspension/brake
components. Use of on-board leveling systems do not require deation or disconnection.
OPERATING TIPS
1. Inate your air springs to 30 PSI (2.1BAR) before adding the payload. This will allow
the air cylinder to properly mesh with the coil spring. After the vehicle is loaded, adjust
your air pressure down to level the vehicle and for ride comfort.
2. When carrying a payload it will be helpful to increase the tire ination pressure in
proportion to any overload condition. We recommend a 2 PSI (.1BAR) increase above
normal for each 100 lbs. additional load on the axle.
TROUBLESHOOTING GUIDE
1. Leak test the air line connections.
2. Inspect the air lines to be sure none are pinched. Zip ties may be too tight. Loosen or replace
the tie and replace leaking components.
3. Inspect the air line for holes and cracks. Replace as needed.
4. Look for a kink or fold in the air line. Reroute as needed.
If the preceding steps do not solve the problem, it is possibly caused by a failed air spring — either
a factory defect or an operating problem. Please call Air Lift at [phone] for assistance.

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 times and how much pressure
will they need?
The recommended minimum air pressure is 5 PSI(.34BAR). 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. Air pressure can be adjusted with any type of compressor as long as it can produce
sufcient pressure to service the springs. Even a bicycle tire pump can be used, but it’s
a lot of work.
Q. How long should air springs last?
If the air springs are properly installed and maintained they can last indenitely.
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
If the vehicle’s headlights are shining into the trees or the vehicle is leaning to one side,
then it is not level (Fig. 10). Raise the air pressure to correct either of these problems
and level the vehicle.
2. Ride comfort
If the vehicle has a rough or harsh ride it may be due to either too much pressure or not
enough (Fig.11). Try different pressures to determine the best ride comfort.
3. Stability
Stability translates into safety and should be the priority, meaning the driver may need
to sacrice a perfectly level and comfortable ride. Stability issues include roll control,
bounce, dive during braking and sponginess (Fig.12). Tuning out these problems usually
requires an increase in pressure.

GUIDELINES FOR ADDING AIR
1. Start with the vehicle level or slightly above.
2. When in doubt, always add air.
3. If the front of the vehicle dives while braking, increase the pressure in the front air bags,
if equipped.
4. If it is ever suspected that the air bags have bottomed out, increase the pressure (Fig. 13).
5. Adjust the pressure up and down to nd the best ride.
6. If the vehicle rocks and rolls, adjust the air pressure to reduce movement.
7. It may be necessary to maintain different pressures on each side of the vehicle. Loads
such as water, fuel, and appliances will cause the vehicle to be heavier on one side
(Fig. 14). As much as a 50 PSI (3.5BAR) difference is not uncommon.
