INSTALLATION INSTRUCTIONS
Read installation instructions in its entirety before installing your Coil-Rite Kit
STEP 1 - VEHICLE PREPARATION
Remove the positive battery cable. With the vehicle
on a solid level surface chock the front wheels. Raise
the rear wheels of the vehicle using a lift or platform
jack rated for your vehicle weight. Lower the vehicle
frame onto jack stands rated for your vehicle's weight
making sure the suspension is fully extended. (DO
NOT use wood or concrete blocks to support the weight
of the vehicle.)
Insert the plastic plug into the hole in the upper
spring seat see Figure "A".
Do not inflate this assembly when it is
unrestricted. The assembly must be restricted by
a coil spring. Do not inflate beyond recommended
operating pressures for your specific vehicle.
Improper use or over inflation may cause property
damage or severe personal injury.

STEP 2 - AIR SPRING PREPARATION
Cut a section of air line tubing 3 inches in length and
inert into the push-to-connect air inlet on the air spring
(a "saw" cut with a sharp knife is preferred). Exhaust
the air from the air spring by rolling it up toward the air
inlet. After the air is exhausted, install the plug into the
tubing coming out of the air spring see Figure "B".
STEP 3 - INSTALL THE AIR SPRING
Insert the bottom of the flattened air spring into the
coil spring through the lowest opening in the coil spring
with the push-to-connect air inlet at the bottom of the
coil spring see Figure "C".

STEP 4 - ADJUST THE AIR SPRING
Push the air spring up into the coil spring by hand or
with a blunt tool, such as a socket extension. DO NOT
use any thing with sharp edges or corners, as this may
damage the air spring.
When the air spring is completely within the coil
spring, remove the plug and tubing section by pushing
the collar on the fitting towards the air spring and pulling
out the tubing. Allow the air spring to return to its
normal shape.
Push the air spring to the top of the coil spring and
insert the lower support between the air spring and the
lower spring seat see Figure "D".
STEP 5 - ROUTE THE AIR LINE
Cut the air line tubing into two equal lengths, making
sure the tubing is cut as squarely as possible (a "saw" cut
with a sharp knife is preferred). Select a location for the
inflation valves in a protected area, such as on the
bumper or body of the vehicle (Note: The inflation valve
will be installed in Step 6).
Insert the air line tubing into the push-to-connect
fitting on the air spring as far as possible. Route the air
line from the air spring to the desired inflation valve
location.
With the tubing routed from the air spring to the
inflation valve location, use the nylon ties supplied to
secure the air line tubing to the vehicle see Figure "E".
Be careful to avoid heat and sharp edges when fastening
the tubing to the vehicle. Route the tubing away from
the exhaust system.
