SECURING THE AIR SPRING TO THE BRACKETS
1. Secure the air spring to the upper and lower brackets using an open ended

16
” wrench
by tightening the two bolts on the top and the two bolts on the bottom of the spring
assembly.
DUE TO THE THICKNESS OF THE LEAF SPRING STACK, TRIM ALL FOUR U-BOLTS
ON EACH SIDE OF THE VEHICLE TO PREVENT BOTTOMING OUT ON THE UPPER
BRACKET (FIG. 14).
2. Check bolts and connectors to ensure that all hardware is secure and repeat the process
for the other side of the vehicle.
5. Remove the clamps and drill the remaining two holes. Install the appropriate hardware
and torque the nuts to 44 ft/lbs.
6. Align the air spring uniformly between the upper and lower brackets and check the air
spring alignment (fig. 13).
INSTALLING THE AIR LINES
WHEN INSTALLING THE AIR LINES, THERE MUST BE AT LEAST SIX INCHES OF
CLEARANCE BETWEEN THE AIR LINES AND ANY HEAT SOURCES.
1. Choose a convenient location for mounting the inflation valves. Popular locations for the
inflation valves are: The wheel well flanges; The license plate recess in bumper; Under
the gas cap access door; or through the license plate (fig. 15).
2. Secure air lines with provided tie straps.
Whatever the chosen location for the line is, make sure there is enough clearance around
the inflation valves for an air chuck.
