10. Complete passenger and driver’s side installation of air spring assembly.

11.Select a location for the air inflation valves. The location can be on the bump­er or body of the vehicle where an air chuck can be used to inflate the air
springs. Select a location where the valve will not be damaged or interfere
with the operation of other components.

12.Cut air brake lines to length and connect air lines to fittings by pushing the air
line into the air fittings as far as possible. A length of heat shielding is provided
to protect the air line as it exits the passenger side air spring.

13. Inflate air springs to 40 psi and check for leaks. A soapy water solution can
be used to find slow leaks.

14.When satisfied with integrity of the system, adjust air pressure to desired level.
The air springs can be inflated to any level between 10 and 50 psi. DO NOT
run the air springs empty or warranty will be void. MINIMUM air spring pres­sure is 5 psi. Failure to keep air in the air springs will void the warranty. For
best RIDE use only enough air pressure as required to level the vehicle. If a
firmer ride is desired, more pressure can be used.

15.Check air pressure in the system regularly to ensure system performance and
maintenance of warranty. Just like tires, the air pressure in the system will
vary due to temperature changes. For your air spring system to function
properly it must be checked on a regular basis.

ATTENTION INSTALLER: BE SURE THAT THE CUSTOMER

RECEIVES THIS INSTRUCTION SHEET, ALL IMORTANT NOTE
CARDS AND THE WARRANTY FORM.
