MAINTENANCE GUIDELINES

NOTE
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
FOR SAFETY AND TO PREVENT POSSIBLE DAMAGE TO THE VEHICLE, DO NOT
CAUTION
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
5. When increasing load, always adjust air pressure to maintain normal ride height. Increase
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
8. Periodically check the air spring system fasteners for tightness. Also, check the air

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

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.
