IV. Installing the Air Lines
1. Choose a convenient location for mounting the inflation
valves. Popular locations for the inflation valve are:
a. The wheel well flanges.
b. License plate recess in bumper.
c. Under the gas cap access door.
d. Through license plate itself.
NOTE: What ever the chosen location is, make sure there
is enough clearance around the inflation valves for an air
chuck.
2. Drill a
5
/
16
" hole to install the inflation valves.
3. Cut the air line assembly (AA) in two equal lengths (Figure
5).
CAUTION: 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 against leaks.
(Figure 6). 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
(Figure 6).
Good cut – clean and
square
Bad cut – flattened

4. Place a

nut (GG) and a star washer (FF) on the air valve. Leave enough of the inflation valve in front
of the nut to extend through the hole and have room for the rubber washer (EE), flat washer (DD), and
5

" nut (GG) and cap (CC). There should be enough valve exposed after installation - approximately
1
/

" - to easily apply a pressure gauge or an air chuck (Figure 7).
5. Push the inflation valve through the hole and use the rubber washer (EE), flat washer (DD), and another
5
/
16
" nut (GG) to secure it in place. Tighten the nuts to secure the assembly in place (Figure 8).
6. Route the air line along the frame to the air fitting on the air spring. 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. Use the plastic tie straps (BB) to secure the air line to fixed, non-moving points along
the chassis. Be sure that the tie straps are tight, but do not pinch the air line. Leave at least 2" of slack
to allow for any movement that might pull on the air line.
7. Cut off air line leaving approximately 12" of extra air line. A clean square cut will ensure against leaks.
8. To properly instal the airline, measure
9
/
16
" from the cut end and mark with tape. Lubricate (i.e. soap
solution, silicone spray, saliva) the end of the air line and insert it into the fitting. This is a push to connect
fitting. A click can be heard/felt when the air line is seated, also, the front edge of the tape band should be
flush with the fitting. The air line is now installed.
