7 SECURE UPPER BRACKET
Place the air spring assembly back in the vehicle.
Secure the upper bracket to the frame using four 3/8” – 16 x 1.5”
bolts, 3/8” thick flat washers, large OD washers and nylon lock nuts
as shown in Figure 7.
Torque all bolts to 40 ft-lbs [54 N•m]
8 SECURE LOWER BRACKET
Attach the lower bracket (and spacer brackets if used) to the leaf
spring with two U-bolts, four 3/8” flat washers and four 3/8” nylon
lock nuts (as shown in Figure 8A).
Leave the fasteners loose at this time.
Position the air spring to achieve the best vertical alignment (as per
Figure 8B).
When spring is aligned, torque the upper and lower air spring bolts to
20 ft-lbs [27 N•m].
Secure the lower bracket by tightening the nuts on the U-bolts to 20
ft-lbs [27 N•m].
When fasteners are tight trim the excess U-bolt length such that it
does not extend above the lower edge of the roll plate.
WARNING: Failure to trim U-bolts can result in air bag puncture
during operation and may void your warranty.
9 INSTALL HEAT SHIELD
Bend tabs on the heat shield so the required ½” of dead space exists
between the heat shield and exhaust when attached.
Attach the heat shield to the exhaust pipe on passenger side using
two ring clamps (shown in Figure 9).
Each hose clamp holds a tab against exhaust pipe.
