INSTRUCTIONS

Congratulations - your new Air Helper Springs are quality

products capable of improving the handling and comfort of your
vehicle.  As with all products, proper installation is the key to
obtaining all of the benefits your kit is capable of delivering.
Please take a few minutes to read through the instructions to
identify the components and learn where and how they are used.
It is a good idea to start by comparing the parts in your kit with
the parts list below.

The heart of the air helper spring kit is, of course, the air

helper  springs.   Remember that the air helper springs must flex
and expand during operation, so be sure that there is enough
clearance to do so without rubbing against any other part of the
vehicle.

Be sure to take all applicable safety precautions during the

installation of the kit.  The instructions listed in this brochure
and the illustrations all show the left, or driver’s side of the
vehicle. To install the right side assembly simply follow the same
procedures.

Your kit includes separate inflation valves and air lines for

each air helper spring. This will allow you to level your vehicle
from side to side as well as from front to back.  If you would rather
have a single valve inflation system, your dealer can supply the
required "T" fitting.

MPORTANT

!

For your safety and to prevent possible damage to your

vehicle, do not exceed the maximum load recommended by the
vehicle manufacturer (GVWR).  Although your Air Helper
Springs are rated at a  maximum inflation pressure of 100 P.S.I.,
this pressure may allow you to carry too great a load on some
vehicles.  Check your vehicle owner’s manual  for maximum
loads listed for your vehicle.

When inflating your Air Helper Springs, add air pressure

in small quantities, checking pressure frequently during
inflation.  The air spring requires much less air volume than
a tire and, therefore, inflates much quicker.

W

ARNING

:

Do not inflate this assembly  when it is unrestricted.

The assembly must be restricted by the suspension
or other adequate structure.  Do not inflate beyond
100 P.S.I.   Improper use or over inflation may cause
property damage or severe personal injury.
