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.

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 or
data plate on driver side door for maximum loads listed for
your vehicle.
When inflating your Air Helper Springs, add air pres-
sure in small quantities, checking pressure frequently dur-
ing inflation. The air spring requires much less air volume
than a tire and, therefore, inflates much quicker.
