Installing the Air Lines
Air lines are routed from the air springs to Schrader valves. LoadLifter 5000 series air
lines come in two styles: nylon and braided stainless steel. Begin by choosing locations
for the Schrader valves and drill a 5/16” (8mm) hole, if necessary (Fig. 28).
KEEP AT LEAST 6” (150MM) OF CLEARANCE BETWEEN ALL AIR LINES AND THE
EXHAUST SYSTEM. AVOID SHARP BENDS AND EDGES.
INSTALLING NYLON AIR LINES
1. Cut the air line in half. Make clean, square cuts with a razor blade or hose cutter
(Fig. 29). Do not use scissors or wire cutters.
2. Use zip ties to secure the air line to fixed points along the chassis. Do not pinch or kink
the air line. The minimum bend radius for the air line is 1” (25mm). Leave at least 2”
(50mm) of slack in the air line to allow for any movement that might pull on the air line.
3. Install the Schrader valve in the chosen location (Fig. 30).

If a location for the Schrader valve other than the back of
the vehicle is chosen, it may be necessary to coil the
excess air line. The braided stainless steel air line cannot
be trimmed.
