IMPORTANT
PLEASE DON’T HURT YOURSELF, THE KIT, OR YOUR VEHICLE. TAKE A MINUTE TO READ THIS IMPORTANT INFORMATION.
SAFE INSTALLATION
Please take all safety precautions during installation. A hydraulic jack can fail, and if that happens, you can be
seriously hurt, or worse, if you are relying on it to hold up the vehicle. If you use a hydraulic jack, secure jack
stands in the appropriate locations and chock any tires still touching the ground.
Wear safety glasses or goggles.Your eyes may be lower than some parts and pieces, and you don’t want to losean eye.
Remove the possibility of any electrical issues by disconnecting the negative battery cable.
VEHICLE GVWR
NEVER exceed the maximum load recommended by the vehicle manufacturer (GVWR).The GVWR can be found
in your vehicle’s owner’s manual or on the data plate on the driver’s side door. Consult your local dealership for
additional GVWR specifications.
PRESSURE TO LOAD
Be sure to review the load limits noted in the Air Spring Kit Installation Instructions (sold separately).
APPROPRIATE AIR PRESSURE
For best ride, use only enough air pressure in the Air Springs to level the vehicle when viewed from the
side (front to rear).This will vary, depending on the load, location of the load, condition of the existing
suspension, and personal preference.
ONCE INSTALLED SUCCESSFULLY, FOLLOW THE PRESSURE REQUIREMENTS FOR THE AIR SPRINGS.

PLANNING THE INSTALL
THESE PLANNING STEPS WILL HELP YOU SAVE TIME AND WILL MAKE THE INSTALLATION EASIER.
DETERMINE THE MOUNTING LOCATION FOR THE AIR COMPRESSOR
- Provides ample air flow and is protected from airborne debris and moisture.
If using the optional Firestone Air Accessory Mounting Kit, consider the
guidelines above, and follow the kit’s instructions.
DETERMINE THE MOUNTING LOCATION FOR THE ECU
Mount close enough to the Air Compressor to allow Wire Harness
connections to reach.
- Allow room for Air Tubing to connect to the Air Fitting on the ECU.
- Allow room for the Air Tubing to run without sharp curves or bends.
Using supplied fasteners shown in Step 3 is recommended. If no other mounting option is available,
see the sidebar on Step 2 for using the Large Nylon Ties.
Select a location that is solid and secure on the body or frame of the vehicle, away from any moving parts,
electrical or any other lines.
PLAN INSTALLATION ROUTES FOR WIRING AND AIR LINES
- Use supplied Thermal Sleeves on Air Tubing when routing near heat sources.
- Use supplied Nylon Ties to secure Air Tubing and Wire Harness to the vehicle.
- Make a loop in the Air Tubing where shown.This creates a water/debris trap that protects the Air Compressor.
- Measure twice, cut once!
TAPE ALL ELECTRICAL CONNECTIONS
- Use electrical tape to appropriately secure and protect all electrical connections.
USING PUSH-TO-CONNECT FITTINGS FOR AIR LINES
Your kit includes Push-to-Connect fittings to connect the Air Tubing to hardware.
Use the instructions below when using the Air Tubing.
1Insert end of Air
Tubing into
Air Fitting. 2Push Air Tubing
into Air Fitting as
far as possible. 3Gently pull on
the Air Tubing
to check for a
secure fit.
4To remove, push
down collar and
gently pull Air
Tubing away.
Removal Tip: Use a 1/4 , 5/16
or 6mm open-ended wrench
to push the collar down.
- Allow room for the 4-pin ECU connector to connect to the ECU.
- Mount close enough to the ECU to allow Wire Harness connections to reach.
- Make sure the Wire Harness and Air Tubing are not exposed to sharp metal edges that can damage them.

around the mounting
location.

CHECK SURROUNDING AREA AND BACK SIDE OF MOUNTING
LOCATION TO AVOID DRILLING INTO EXISTING LINES OR WIRING.
1Using the Air Compressor
and ECU as templates, mark
a punch or marking tool.
2Mark Air Compressor

3Drill 7/32" diameter holes.
Remove any burrs and
debris from drill holes.

AIR COMPRESSOR AND ECU CLOSE
ENOUGH SO THE CONNECTORS ON
THE WIRE HARNESS WILL REACH
THEM BOTH.

Barb into the Air Tubing
from the Air Compressor Kit. 2Press Air Tubing onto the
Barb on the Air Compressor
Air Fitting until fully seated.
Assure you create a loop in
the Air Tubing, as shown,
when securing it to the
vehicle.
3Periodically check the Air
Filter during operation.
When the Air Filter is dirty
and needs to be replaced,
contact an Authorized
Firestone dealer to
purchase a new one.
SECURE THE AIR FILTER IN A LOCATION THAT
PROTECTS IT FROM MOISTURE AND DEBRIS,
AND IS ABOVE THE LOOP INTHE AIR LINE TUBE.

BEFORE YOU DRIVE, CONFIRM THE FOLLOWING:
Secure all AirTubing and wiring.
The system passes the leak test and holds air.
The Air Compressor ground ring terminal is contacting bare metal, and coated with silicone if possible.
The Wire Harness is grounded to the negative (-) battery terminal.The ECU needs a good, clean,
interference-free ground.
There is a loop in the AirTubing as shown to prevent water or debris from getting into the Air
Compressor head and damaging it.
