MAINTENANCE GUIDELINES
By following the steps below, vehicle owners will obtain the longest life and best results from
their air springs.
1. Check air pressure weekly.
2. Always maintain normal ride height. Never inflate beyond 100 PSI (6.9BAR).
3. If the system develops an air leak, use a soapy water solution to check all air line
connections and the inflation valve core before deflating and removing the air spring.
FOR SAFETY AND TO PREVENT POSSIBLE DAMAGE TO THE VEHICLE, DO NOT
EXCEED MAXIMUM GROSS VEHICLE WEIGHT RATING (GVWR), AS INDICATED BY
THE VEHICLE MANUFACTURER. ALTHOUGH THE AIR SPRINGS ARE RATED AT A
MAXIMUM INFLATION PRESSURE OF 100 PSI (6.9BAR), THE AIR PRESSURE ACTU-
ALLY NEEDED IS DEPENDENT ON LOAD AND GROSS VEHICLE WEIGHT RATING .
4. Loaded vehicles require at least 25 PSI (1.7BAR). A “loaded vehicle” refers to a vehicle
with a heavy bed load, a trailer or both. Never exceed GVWR, regardless of air spring,
air pressure or other load assist. The springs in this kit will support approximately 40
pounds (18kg) of load (combined on both springs) for each 1 PSI (.07BAR) of pressure.
The required air pressure will vary depending on the state of the original suspension.
Operating the vehicle below the minimum air spring pressure will void the Air Lift
warranty.
5. When increasing load, always adjust 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.
6. Always add air to springs in small quantities, checking the pressure frequently.
7. Should it be necessary to raise the vehicle by the frame, make sure the system is
at minimum pressure (5 PSI [.34BAR] ) to reduce the tension on the suspension/
brake components. Use of on-board leveling systems do not require deflation or
disconnection.
8. Periodically check the air spring system fasteners for tightness. Also, check the air
springs for any signs of rubbing. Realign if necessary.
9. On occasion, give the air springs a hard spray with a garden hose to remove mud,
sand, gravel or other debris.
