FINAL NOTES
After installation is complete, double check that all nuts & bolts are tight. Refer to the following chart for proper
torque specifications.
NOTE:
Do not re-tighten nuts & bolts where thread lock compound was used.
With vehicle placed on ground, cycle steering lock to lock & inspect steering, suspension, brake lines, front & rear drive
lines, fuel lines & wiring harnesses for proper operation, tightness & adequate clearance.
Have headlights readjusted to proper settings.
Have a qualified alignment center align vehicle to OEM specifications.
After first 100 miles, check all hardware for proper torque & periodically thereafter.

COLDER CLIMATE TIPS
In the winter months, to keep your air system
from freezing, we recommend adding CRC air
brake antifreeze. This can be purchased at most
automotive parts houses. We recommend that you
add two caps (about 1 ounce) to the system through
the compressor intake. To do this, you should adjust
the suspension to deplete the air in the tank so the
compressor will be running while you do this process.
You want to slowly add the antifreeze to the system
so it has time to vaporize and coat everything. You
will need to do this periodically depending on how
much use the vehicle has. Generally, once every two
weeks will but can vary.

1. Start vehicle. Make sure there are no dash lights pertaining to suspension.
2. Bounce the vehicle a couple of times. This will help suspension settle to new ride height. Cycle steering lock-to-
lock & check all components for proper operation & clearances. Pay special attention to clearance between tires/
wheels, Shocks, control arms, brake hoses, ABS wiring, etc.

CHECK FOR SYSTEM LEAKS
Place all 4 wheels on the ground and inflate air springs with the TouchPad. Check for system leaks using soapy water
on all pneumatic connections to the air springs and the regulator.
CALIBRATION
Once system installation is complete, the system will need to be calibrated. Calibration is
a process that will learn the vehicle range of travel and automatically set ride heights.
The vehicle needs to be on level ground with the wheels pointed straight ahead. Leave
the vehicle running to power the compressor(s) during this procedure.
Before starting calibration, turn on the vehicle and let the compressors run to fill the tank. Once
the compressor stops running (green “C” on TouchPad stops blinking) you may simultaneously
hold the “dot” and “1” button for 5 seconds. You may let go when the vehicle starts to move up.
The vehicle will now open the valves to the air springs and run the compressor to fill all
air springs. The system will continue doing this until the set pressure is achieved at which
point the maximum suspension travel will be defined.
Next, the vehicle will exhaust all air from the air springs to define the minimum travel.
Calibration is complete when the system
prompts a position 2 two adjustment (“2” will
be flashing on the TouchPad). This may take
some time as the system has to fill the tank and
air springs from near empty.
CALIBRATION VIDEO
The system will automatically
raise/lower
the vehicle
in the next procedure. Remove all obstructions and
keep clear of vehicle before proceeding.
