READ INSTALLATION INSTRUCTIONS COMPLETELY BEFORE INSTALLING YOUR COIL-RITE KIT
STEP 1— AIR SPRING PREPARATION
With the vehicle on a solid level surface chock the
wheels and raise the vehicle using a jack rated for your
vehicle weight to lift the wheels off the surface. Remove
the wheels. Lower the vehicle frame onto jack stands
rated for your vehicles weight making sure the suspen-
sion is fully extended. (Do
NOT use wood or concrete
blocks to support the weight of the vehicle.)
If necessary, additional clearance between the coil
turns may be obtained by removing the shock absorb-
ers from the lower shock mounts and lowering the sus-
pension an additional one to two inches. (CAUTION:
Do not put strain or tension on the flexible brake line.)
Cut a section of air line tubing approximately three
inches in length. (Cut the tubing as squarely as possi-
ble.) Install the tubing into the push-to-connect air inlet
on the air spring. Exhaust the air from the air spring
by rolling it up toward the air inlet. After all the air is
removed from the air spring install the hose plug into
the end of the hose as shown in
Figure “A”.
STEP 2— PLACING SUPPORTS
Insert the support between the air spring and the coil
spring seat as shown in
Figure “B”.
STEP 3— INSTALLING THE AIR SPRING
Insert the top of the flattened air spring into the coil
spring through the lowest opening with the push-to-
connect air inlet at the top as shown in
Figure “A”.
Push the air spring up into the coil spring by hand
or with a blunt tool, such as a spoon shaped tire iron.
Do
NOT use anything 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 three inch tubing sec-
tion by pushing the collar on the fitting towards the air
spring and pulling on the tubing to remove. Allow the
air spring to return to its normal shape.
STEP 4— REATTACH THE SHOCK
ABSORBER
Attach shock absorbers if removed earlier in the instal-
lation.
WARNING
Do not inflate this assembly when it is
unrestricted. The assembly must be restricted
by a coil spring. Do not ever inflate beyond
recommended operating pressures for your
specific vehicle. Improper use or over inflation
may cause property damage or severe
personal injury.
