AIRLINE INSTALLATION
Provided in the basic air spring kit are two fill valves, the most common place to
install them is to replace the license plate fasteners with the fill valves. Alternatively,
two holes can be drilled in a convenient location. Install one airline provided, route
the nylon hose to an air spring fitting, cut the hose and connect to the air spring
fitting. Repeat with the other fill valve. Secure airlines with the tie-straps provided
away from moving items and heat sources.
If an in cab inflation kit is being installed, follow the instructions provided with it.
NOTE: This kit contains push to connect fittings, using scissors or wire cutters to cut the nylon airline will distort the
line and cause the connection to leak. THE AIRLINE MUST BE CUT OFF SQUARELY WITH A SHARP RAZOR
KNIFE. Moisten the end of the airline prior to inserting it into the fitting and push it in until it stops.
IMPORTANT!
Double check all the fasteners are torques to specification

LEAK CHECK
Inflate both the air springs to 90 PSI. Use a dish soap and water mixture on all
airline connections to detect air leaks. Repair as necessary and retest. Inflate
your air springs to a pre-determined value, then the following day recheck the
pressure. If one or both the air springs have lost pressure, a leak is present.
The leak must be repaired, then retest until no leaks exist.
SPECIAL NOTE:
Retorque all the fasteners after the first 500 miles of driving.
OPTIONAL ACCESSORIES
Pacbrake offers an optional dual needle air gauge to monitor the pressure in each air spring from the vehicles
cab. Pacbrake offers a full line of air compressors, air tanks and solenoids to control your air spring system.
OPERATING YOUR VEHICLE WITH PACBRAKE AIR SUSPENSION
Air springs have minimum and maximum pressure requirements, never operate your vehicle with less then
10 PSI in the air spring and never inflate the air springs over 100 PSI, damage to the air springs will result.
Check the air pressure in the air springs daily for the first couple of days to ensure a leak does not develop.
The air springs are designed to maintain the vehicles stock ride height with a load. Do not use the air springs
as a means to lift the vehicle with no load, a rough ride will result.
SERVICING YOUR VEHICLE WITH PACBRAKE AIR SUSPENSION
When lifting the vehicle with a floor jack or hoist on the frame never allow the air spring to limit the travel of the
axle, try to always jack the vehicle on the axle. Suspending the axle with the air spring limiting the axle travel will
damage the air spring and void the air spring warranty.
WARRANTY
To be eligible for warranty, owner must submit their warranty card or register online within 30 days of purchase
date. NOTE: The owners warranty will be void if air springs run with less than the minimum of 10PSI
