Read installation instructions in its entirety before installing your Coil-Rite Kit
STEP 1 - VEHICLE PREPARATION
Remove the negative 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. Lower the
vehicle's frame on to 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.
Remove the rear wheels from the vehicle.
On 1999 to current Honda Odysseys and Hyundai Entourage,
a 1/2" hole will have to be drilled in the lower control arm to where
the coil spring is centered to allow the air line to pass through.
Make sure that the hole is aligned with the location of the pushÂto-connect air fitting on the installed air spring see Figure "A".
Remove any burrs from the hole to prevent damage to the air
spring. Make sure that the air spring is not installed when the
hole in the lower spring seat is drilled.
STEP 2 - COIL SPRINGS
4138 / 4179
WARNING:
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.
FOR BEST RIDE use only enough air pressure
in the air helper springs to level the vehicle when
viewed from the side (front to rear). This amount will
vary depending on the load, location of load, condition
of existing suspension and personal preference.
It will be necessary to remove the coil springs from the
vehicle in order to install the Coil-Rite kit. Remove the wheel
sensor wire from the lower control arm by unbolting it see Figure
"B". Do not disconnect the wheel sensor connector. Position
a floor jack underneath the point where the lower control arm
connects with the knuckle. Raise the jack until it makes contact
with the lower arm. Remove the flanged hex bolt and lock nut
securing the lower control arm to the knuckle see Figure "B".
Carefully lower the floor jack, allowing the lower control arm to
fall away from the knuckle. Remove the coil spring and upper
and lower spring seats. Hint: Using a crayon or grease pencil,
put a mark across the coil spring, lower spring seat, and lower
control arm as a means to align the spring seat and coil spring
with the lower control arm when reinstalled.

COIL-RITE INSTALLATION PROCEDURE
STEP 3 - OVERLOAD BUMPERS
The factory overload bumpers inside the coil springs must
be removed to provide clearance for the installed air spring.
Remove the overload bumper by removing the flanged hex bolt
securing it to the vehicle's body see Figure "A". Do not discard
the overload bumper hex bolt. It will be used to install the support
in Step 4.
STEP 4 - INSTALL THE SUPPORTS
Install the provided support in place of the factory overload
bumper. This will prevent the metal bumper mount from
damaging the air spring. Install the support using the original
overload bumper bolt so that the bolt head is recessed into the
support see Figure "C".
STEP 5 - PREPARE THE AIR SPRINGS
Cut a section of air line tubing 3 inches in length and insert
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 in the air spring see
Figure "D".

SUPPORT
With the push-to-connect air fitting towards the bottom,
slide the air spring into the coil spring and center it vertically in
the coil spring. Remove the plug and tubing installed in the
push-to-connect air fitting. Push the collar on the fitting towards
the air spring and pull out the tube. Allow the air spring to return
to its normal shape.
Cut the remaining air line tubing into two equal lengths (a
"saw" cut with a sharp knife is preferred). Insert the tubing into
the push-to-connect fitting on the air spring as far as possible.
Install the lower spring seat on the coil spring so that the air line
runs through the center of the spring seat see Figure "E". Place
the coil spring and lower spring seat on the lower control arm.
Carefully pull the air line through the hole drilled in the lower
control arm, being careful not to kink the tubing. Next, install the
upper spring seat on top of the coil spring. Ensure that the upper
and lower spring seats are seated properly on the coil spring.
