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 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.

Your kit includes separate inflation valves and air lines for

each air helper spring. This will allow you to level the vehicle

left-to-right. 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 P.S.I.,

this pressure may allow you to carry too heavy of a load on

some vehicles. Check your vehicle's 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 springs require much less air volume than a tire and,

therefore, inflate much more quickly.

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 P.S.I. Improper use or over

inflation may cause property damage or severe

personal injury.

STEP 1 - PREPARE THE VEHICLE With the vehicle on a solid, level surface chock the rear wheels. Remove the negative battery cable. Raise the vehicle by the front axle and remove the front wheels. After the removal of the wheels, lower the vehicle so the axle rests on jack stands rated for your vehicles weight. Remove the jounce bumpers by unbolting them from their location under the frame rail directly above the axle see Figure "B".

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.
