2. Choose a convenient location for mounting the inflation valves. Popular locations for the
inflation valve are:
The wheel well flanges; The license plate recess in bumper; Under the gas cap access
door; Through license plate.
Whatever the chosen location is, make sure there is enough clearance around the inf lation
valves for an air chuck.
3. Drill a 5/16” hole to install the inflation valves.
4. Cut the air line assembly (AA) in two equal lengths.
When cutting or trimming the air line, use a hose cutter (Air Lift P/N 10530), a razor blade
or a sharp knife. A clean, square cut will ensure that the line will not leak. Do not use wire
cutters or scissors to cut the air line. These tools may flatten or crimp the air line causing it
to leak around the O-ring seal inside the elbow fitting.
5. Install the inflation valves as shown in Figure 10.

6. Keep at least 6” of clearance between the air line and heat sources, such as the exhaust
pipes, muffler, or catalytic converter. Avoid sharp bends and edges. Leave at least 2”
of slack when securing the air lines to allow for any movement that might pull on the air
line.
7. Cut off air line leaving approximately 12” of extra air line. Insert the air line into the air
fitting. Simply push the air line into the 90° swivel fitting until it bottoms out (9/16” of air
line should be in the fitting).
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 to check for leaks. You should be able to 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 Normal
Ride Height, but not less than 5 PSI
Check the air pressure again after 24 hours. A 2 to 4 PSI loss after initial installation is
normal. Retest for leaks if the loss is more than 5 lbs.
