VII. Installing the Air Lines
1. 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, or 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.
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. 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.

4. Place a
5
/16 " 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
/16 " nut (GG) and cap
(CC). There should be enough valve exposed after installation - approximately
1
/2 " - 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 7).
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. Insert the air
line into the air fitting. This is a push to connect fitting. Simply push the air line into the straight fitting until it bottoms
out (
9
/16" of air line should be in the fitting).
VIII. Final Adjustments
1. Inflate both rolling lobe air sleeves to 25 p.s.i and check for leaks (refer to section IX).
2. Tighten both bottom rolling lobe mounts securely at this time.
3. The vehicle was set up for a rear top of frame height of 31”. Do not deviate from this height.
4.With the rear top of the frame at 31”, torque both 16mm pivot bolts on the front of the beam to 110 ft/lbs.
5. IMPORTANT: Check and re-torque all mounting hardware, especially the beam U-bolts, after 100 and 3,000
miles.
