MAINTENANCE GUIDELINES
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 inate beyond 100 PSI.
3. If you develop an air leak in the system, use a soapy water solution (1/5 liquid dish
soap and 4/5 water) to check all air line connections and the ination valve core before
deating and removing the air spring.
FOR YOUR SAFETY AND TO PREVENT POSSIBLE 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 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
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.
5. When increasing load, always adjust the air pressure to maintain the 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 deation 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 in order to remove
mud, sand, gravel or other abrasive debris.
