Tuning the Air Pressure

1.  Inflate the air spring to 80 PSI.
2.  Spray all connections and the inflation valves with a solution of 1/5 liquid dish soap and 

4/5 water . Spot leaks easily by looking for bubbles in the soapy water .

3.  After the test, deflate the springs to the minimum pressure required to restore the system 

to normal ride height .

4 .  Check the air pressure again after 24 hours . A 2-4 PSI loss after initial installation is 

normal . Retest for leaks if the loss is more than 5 PSI .

Checking for leaks

Pressure determination comes down to three things — level vehicle, ride comfort, and stability .

1 .  Level vehicle

  If the vehicle’s headlights are shining into the trees or the vehicle is leaning to one side, 

then it is not level . Raise the air pressure to correct either of these problems and level 

the vehicle .

2 .  Ride comfort

  If the vehicle has a rough or harsh ride it may be due to either too much pressure or not 

enough . Try different pressures to determine the best ride comfort . See Air Lift suggested 

driving air pressure . 

3 . Stability

  Stability translates into safety and should be the priority, meaning the driver may need 

to sacrifice a perfectly level and comfortable ride. Stability issues include roll control, 

bounce, dive during braking and sponginess. Tuning out these problems usually requires 

additional air pressure, strut damping, or both .

1 .  If there is a problem with a swivel fitting:

a.  Check  the  air  line  connection  by  deflating  the 

spring and removing the line by pulling the collar 

against the fitting and pulling firmly on the air line. 

Trim 1” off the end of the air line . Be sure the cut 

is clean and square (see Fig. 28). Reinsert the 

air line into the push-to-connect fitting.

b .  Check the threaded connection by tightening 

the swivel fitting another 1/2 turn. If it still leaks, 

deflate the air spring, remove the fitting, and re-

coat the threads with thread sealant . Reinstall by 

hand tightening as much as possible and then 

use a wrench for an additional two turns .

2 .  If the preceding steps have not resolved the problem, 

call Air Lift customer service at (800) 248-0892 .
