INSTALLATION 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
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.
PARTS LIST
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.
IMPORTANT!
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
psi, this pressure may allow you to carry too great a load on
some vehicles. It is best to have your vehicle weighed once
it is completely loaded and compare that weight to the
maximum allowed. 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.
