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.

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

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 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.
