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  kit  is,  of  course,  the  air  springs.

Remember  that  the  air  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 side of the

vehicle. To install the right side assembly simply follow the

same  procedures.

This kit includes inflation valves and air lines for each

air spring. This will allow you to compensate for unbal-

anced loads. If you would rather have a single inflation

valve system to provide equal pressure to both air springs,

your dealer  can supply the optional "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 psi, this pressure may allow you

to carry too great a load on some vehicles.  Check your

vehicle owner’s manual or manufacture plate on

driver side door  for maximum loads listed for your

vehicle.

When inflating your Air Helper Springs, add air

pressure in small quantities, checking pressure fre-

quently during inflation.  The air spring requires much

less air volume than a tire and, therefore, inflates much

quicker.

WARNING:

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 psi   Improper use or over

inflation may cause property damage or severe

personal injury.

Installation of this kit requires a

minimum of 6" of clearance between the

tire side wall and the vehicle frame and a

1/2" of clearance around the air spring

when inflated.

ATTENTION:

Due to frame to tire clearance, this kit may not

fit vehicles with some brands of 5

th

 Wheel or

Gooseneck hitches as this kit must be bolted to

the vehicle frame and not the hitch plates.
