another 5/16" nut. Tighten the nuts to secure the assembly in place (fig. 8).
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.
against leaks (see fig. 7). 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 until it bottoms out (9/16" of air
line should be in the fitting).
approximately 10 p.s.i. Use the slots in the brackets to correctly align the air spring
between the upper and lower brackets. This can be accomplished by tapping it inboard
or outboard for proper alignment. There should be symmetrical cushion of air around
the base of the air spring when correctly positioned.

a. Check the air line connection by deflating the spring and removing the line by pulling
the collar against the fitting and pulling firmly on the air line. Trim 1" off the end of
the air line. Be sure the cut is clean and square (see fig. 7). Reinsert the air line into
the push-to-connect fitting.
b. Check the threaded connection by tightening the swivel fitting another ½ turn. If it still
leaks, deflate the air spring, remove the fitting, and re-coat the threads with thread
sealant. Reinstall by hand tightening as much as possible, then use a wrench for an
additional two turns.
a. Check the valve core by tightening it with a valve core tool.
b. Check the air line connection by removing the air line from the barbed type fitting.
