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 .
3 .  If the system develops an air leak, use a soapy water solution (1/5 liquid dish soap 

and 4/5 water) 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, THE AIR PRESSURE ACTUALLY 
NEEDED IS DEPENDENT ON LOAD AND GVWR .

4 .  Loaded vehicles require at least 25 PSI . 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 
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 .

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 become necessary to raise the vehicle by the frame, make sure the 

system is at minimum pressure (5 PSI) 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 .
