7. Cut off the air line, leaving approximately 12” of extra air line. A clean square cut will
ensure against leaks. Insert the air line into the air fitting. This is a push-to-connect fitting.
Simply push the air line into the 90° swivel fitting (D) until it bottoms out (9/16” of air line
should be in the fitting).
8. Install the minimum/maximum air pressure decal in a highly visible location. We suggest
placing the decal on the driver-side window, just above the door handle.
INSTALLING THE HEAT SHIELD
1. Bend tabs to provide a ½” dead air space between exhaust pipe and heat shield (g. 22).
2. Attach the heat shield to the exhaust pipe using the clamps. Bend the heat shield for
maximum clearance to the air spring (g. 22).
CHECKING FOR LEAKS
1. Inflate the air spring to 30 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. Do not deflate to lower than 5 PSI.
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 lbs.
FIXING LEAKS
1. If there is a problem with the swivel fitting:
a. Check the air line connection by deating the spring and removing the line by pulling
the collar against the tting and pulling rmly on the air line. Trim 1” off the end of
the air line. Be sure the cut is clean and square (see g. 19). Reinsert the air line
into the push-to-connect tting.
b. Check the threaded connection by tightening the swivel tting another ½ turn. If it still
leaks, deate the air spring, remove the tting, 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.
