NOTE:
Please read thorough this manual completely before installing the air
spring kit on your vehicle.
STEP 1 — PREPARE THE VEHICLE
With the vehicle on a solid, level surface chock the front wheels.
Remove the negative battery cable. Your vehicle is equipped with
rubber jounce bumpers. The jounce bumpers are bolted to the frame
above the axle. Remove the jounce bumpers from the vehicle.
STEP 2 — PRE-ASSEMBLE THE KIT
Select a lower bracket from your kit and determine which side of the
Figure
“A”. NOTE: The smaller side is for the gasoline engine axle and
the larger side is for Diesel engine axle.Select one air spring, bail
clamp and lower bracket from your kit. Place the bail clamp in the
correct position in the slot of the lower bracket for your vehicle. Install
the air spring to the lower bracket using the hole for your vehicle with
Please
see the lower right section of Figure “A”. The bolt will be tightened
up in STEP 5.
STEP 3 — INSTALLING THE UPPER BRACKET TO THE
VEHICLE
Select an upper bracket from your kit. Install the upper bracket to the
Figure “A”.
STEP 4—INSTALLING THE ASSEMBLY TO THE VEHICLE
Position the lower bracket and air spring assembly from STEP 2 on
the axle as shown in Figure “A”. Put the large threaded stud though
the large hole on the upper bracket and the locating pin of the air
spring in the small hole on the upper bracket as shown in Figure “A”.
Make sure the aliment pin is in the locating hole before fasting
air spring to the upper bracket. Fasten the air spring to the upper
bracket using ¾"-16 hex head nut and ¾" star washer. Fasten the
lower bracket to the axle housing using the bail clamp and the axle
securely to engage the orange thread sealant.
STEP 5— INSTALLATION OF THE PASSENGER’S SIDE
ASSEMBLY
Before following STEPS 1-4 with reverse orientations for assembly
and installation of the passenger’s assembly, a heat shield will need
to be mounted between the upper bracket assembly and the top plate
of the air spring, see Figure “B”. Position the heat shield directly
between the closest heat source and the air spring. Ensure that the
heat shield will not interfere with normal operation of the air spring
or the vehicle’s suspension. Do not position the heat shield directly
above the axle, as it may contact the axle on full suspension travel.
FIGURE “B” (Step 5)
Important:
In order for the air spring
to function properly, there
must be a minimum of 1/2"
of clearance around the air
spring.

The LevelTow Compressor System is an automatic leveling system, once it is turned on(button
illuminated blue) it will operate without any assistance.
to keep the vehicle level. It has a dwell range built in so that when the truck is going down the
road hitting small defects the system will be idle. It isn’t until the sensor gets out of this dwell
range for 18 seconds that the system will react.
The activation switch has to be illuminated blue for the system to work.

1. Before you install the compressor system,
you will need to have the helper Airsprings
installed. This will ensure that the LevelTow
linkage does not get in the way of the Air-
springs.

the fender to the ground at the center of the
wheel and write it down.

This measurement will be used as a refer-
ence once you have the compressor system
installed.
2. Unpack the wiring for the LevelTow sys-
tem and lay it out. This will give you an idea
to where you can mount the components
without having to modify the wiring harness.
NOTE:
There is a wiring diagram on Page 7 to assist
you in component location.

3. Remove the nut from the stud on the com-
pressor that is sticking down. Stick the studs
into the holes on the keyhole slots and slide
the compressor into the locked position. Re-
install the nut and tighten. Tighten the nuts
on the bottom of the studs also. This will se-
cure the compressor to the frame mounting
plate.
NOTE:
The diagram shows the position the com-
pressor goes onto the plate.
4. With the nuts secured the compressor will
will pull down against the mounting plate.
5. The compressor needs to be mounted
on the frame rail with the opening up. The
rubber shield will protect it from road debris.
Attach the compressor bracket to the frame
with 4 self drilling screws supplied in the kit.
NOTE:
Before drilling any hole be sure to check and
see if there are any brake lines, fuel lines, or
wires on the other side of the surface you are
drilling.

on the frame and out of direct tire spray. The
hose on the drain should be coming straight
out of the bottom. There is a drain in the bot-
that might get into the housing. Be sure that
ing to the compressor assembly.
7. The Axle bracket can be mounted in any
location on the axle tube to get the sensor
linkage to line up. The Axle mount should
be mounted on the axle so that the linkage
will line up from the axle mount to the sensor.
Keep this in mind when establishing the sen-
sor location.
8. The next step will be to mount the sen-
sor. The Smart Sensor needs to be centered
in its travel at the trucks ride height to oper-
ate properly. This can be done by cutting the
loosening the 4 sensor mounting screws and
twisting it in the mount and retightening the
4 screws. When the mounting and linkage
is done it should look like the diagram seen
here.
Page 7
9. The sensor needs to be mounted on the
frame rail with the wires pointing down. The
arm will need to swing up opposite the direc-
tion of the wires as the suspension is being
compressed. Attach the sensor bracket to
the frame with (4) self drilling screws sup-
plied with the kit.
NOTE:
The sensor can be mounted on the inside or
outside of the frame. Make sure the linkage
and arm can go through its entire travel with-
out hitting any obstructions
10. This diagram shows how the clamp
sticks through the axle bracket. Loosen the
clamp until it will open up and then slide it
through the bracket. The whole assembly
can then be put on the axle tube. Reinsert
the end of the clamp back into the adjuster
and tighten the clamp until the bracket is
tight on the axle tube.
11. With the sensor and the axle bracket
mounted, it is time to connect the 2 with the
supplied linkage. The linkage is a universal
length and will have to be cut to achieve the
necessary length for your application. To do
this it will be necessary to have the truck sit-
ting at its factory ride height. With the truck
at ride height center the sensor in its travel.
The rod can slide into each rubber rod end
up to 1”.
Page 8
12. The 2 pieces of heat shrink supplied in
the kit will hold the linkage together after your
length is determined. To apply the heat shrink
slide one piece over the rubber endlink as far
as it will go on to the rod side. Heat the heat
shrink with a heat
gun(hair dryer or small torch will work) until it
shrinks down to the rubber. Continue heating
the heat shrink to the rod until secured. Be
sure not to over heat the tubing causing it to
pull from the rubber end.
13. Mount the control panel in a convenient
location. Install the Power Button and Manu-
al Control Rocker into the panel. The Power
Button gets installed into the round hole. The
nut that is on the button is used to attach the
button in the panel. The Rocker Switch goes
into the hole with the notch in it. Align the
tab on the switch with the slot and push the
switch into the hole until it snaps in place.
The rocker will only go into the hole one way.
You can also custom mount the buttons if de-
sired. They both use a 3/4” hole. The hole
for the manual switch will have to have a slot
for the tab
14. Hook the wires up to the manual control
switch as shown in the diagram.

or lower you can adjust the height by loos-
ening the 4 screws that attach the sensor

height can not be achieved by adjusting in
the bracket the linkage will need to be length-
ened or shortened to achieve the height you
need.

Unhook one end of the linkage and move the sensor arm by hand. If when you move the arm down (Keep in
ness at the sensor. To do this, with the truck turned off, simply unplug the harness from the sensor. Using
a small screwdriver pop the purple retainer out of the plug by prying up on each end of it. After removing the
retainer if you look into the end of the plug you will see a tang holding each wire terminal. Simply pry it down
just enough to release the terminals of the blue and green wires. Swap the blue and green wire postion and
reinstall the wires into the plug paying attention to the direction of the small tab on the wire terminal. This
tab will point to the center of the plug. Push the wire terminals into the plug making sure they catch on the
