PARTS LIST

INSTALLATION I NSTRUCTIONS

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.

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. 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 more quickly.

STEP 1 - PREPARE THE VEHICLE REMOVE THESE BOLTS PRIOR TO INSTALLATION OF THE UPPER BRACKET With the vehicle on a solid level surface, chock the front and rear wheels and apply the parking brake. It will not be necessary to raise the rear of the vehicle for this installation. Your vehicle is equipped with rubber jounce bumpers. The bumpers are attached to a bracket on the frame directly above the axle. The bracket is riveted to the frame and to an angle bracket beneath the frame rail.

STEP 5 - INSTALL THE AIR LINE AND INFLATION VALVE Uncoil the air tubing and cut it in two equal lengths. DO NOT FOLD OR KINK THE TUBING. Make the cut as square as possible. Insert one end of the tubing into the push-to-connect elbow fitting installed in the top of the air helper spring as far as possible. Select a location on the vehicle for the air inflation valves.

SAFETY TIPS Never exceed the manufacturer’s recommended Gross Vehicle Weight Rating (GVWR) As with your vehicle’s tires, an air helper spring is a pneumatic device that supports a portion of the vehicle’s weight. The air helper spring may fail as a result of punctures, impact damage, improper inflation, improper installation, or improper usage. To reduce the risk of failure, we strongly recommend the following: Never overload your vehicle.

the suspension system. As more air pressure is added to the air springs, they will support more weight. You will be able to compensate for a heavy load by adding air pressure to the air springs, thereby reducing sway and handling problems associated with a heavily loaded vehicle.
PAGE 8
INFLATING THE AIR SPRINGS With the air helper springs installed on your vehicle and the vehicle sitting on a level surface, visually verify that the vehicle is in a level state. If the vehicle is not level (front-to-back or from side-to-side) it can be brought to a level position by inflating the air springs. Each air spring has a separate inflation valve. To level the vehicle from front-to-back, add air pressure to both air springs in equal amounts.
