Installation Instructions
WARNING:
Do not inate this assembly when it is
unrestricted. The assembly must be restricted
by a coil spring. Do not ever inate beyond
recommended operating pressure for your
specic vehicle. Improper use or over ination
may cause property damage or severe
personal injury.
RECOMMENDED OPERATING PRESSURES
PASSENGER CARS, CUVs AND VANS 5–35 PSI
STEP 1 — PREPARE THE VEHICLE
Remove the negative battery cable. With the vehicle on
a solid level surface chock the front wheels. Raise the
rear of the vehicle using a lift or platform jack rated for
your vehicle's weight. Remove the rear wheels. Lower the
vehicle 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.
STEP 2 — SHOCK ABSORBERS
If necessary, additional clearance between the coil spring
turns may be obtained by removing the shock absorbers
from the lower mounts and lowering the suspension an
additional one to two inches. Do not put strain or tension
on the exible brake line.
NOTE:
If your vehicle is equipped with vibration dampers
between the turns of the coil, it is necessary that
these be removed before installing the air springs.
STEP 3 — PREPARE THE AIR SPRING
Remove one air spring from your Coil-Rite kit. Depress
the valve stem and deate the air spring as much as pos-
sible. After deating the air spring roll it tightly lengthwise
and hold in that position.
STEP 4 — INSTALL THE AIR SPRING
Insert the top of the attened air spring into the coil spring
through the lowest opening of the coil spring with the air
inlet at the bottom of the coil spring, see Figure "A".
STEP 5 — ADJUST THE AIR SPRING
Push the air spring up into the coil spring by hand or with
a blunt tool, such as a 1/2" socket extension. Do NOT
use any thing with sharp edges or corners, as this may
damage the air spring.
Once the air spring is completely inside the coil
spring depress the valve stem and allow the air spring
to return to its normal position.
Insert the lower support between the air spring and
the lower spring seat, see Figure “B”.
STEP 6 — REATTACH THE SHOCK ABSORBER
Remove the tubing from the hose kit and cut it into two
equal lengths (cut the tubing as squarely as possible).
Select a location for the ination valves in a protected
area, such as: under the hood or on the bumper (Note:
ination valve will be installed in Step 8).
Attach the elbow tting to the air spring nger tight.
Route the air line from the air spring to the desired loca-
tion of the ination valve, see Figure “C”.
STEP 7 — HOSE ATTACHMENT TO THE VEHICLE
With the tubing routed from the air spring to the location
of the ination valve. Use the nylon ties supplied, secure
the air line tubing to the vehicle as shown in Figure "C".
Be careful to avoid heat and sharp edges when fastening
the tubing to the vehicle. Stay away from the radiator and
exhaust system.
