MAINTENANCE GUIDELINES

NOTE
By following the steps below, 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 inflate beyond 100 PSI.
3 . If you develop an air leak in the system, use a soapy water solution (1/5 liquid dish
FOR YOUR SAFETY AND TO PREVENT POSSIBLE DAMAGE TO YOUR VEHICLE, DO
CAUTION
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 100 P .S .I ., THE AIR PRESSURE ACTUALLY
NEEDED IS DEPENDANT ON YOUR LOAD AND GVWR .
4. Loaded vehicles require at least 25 PSI or more. A "loaded vehicle" refers to a vehicle
5 . When increasing load, always adjust the air pressure to maintain the normal ride height .
6 . Always add air to springs in small quantities, checking the pressure frequently .
7 . Should it become necessary to raise the vehicle by the frame, make sure the system is at
8 . Periodically check the air spring system fasteners for tightness . Also, check the air springs
9 . On occasion, give the air springs a hard spray with a garden hose in order to remove

with a heavy bed load, a trailer, or both . As discussed above, never exceed GVWR,
regardless of air spring, air pressure, or other load assist . The springs in this kit will support
approximately 40 lbs . of load (combined on both springs) for each 1 PSI 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 .
