INSTALLATION INSTRUCTIONS

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 benets 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 springs. Remember that the air helper springs must

ex 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 ination 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 ination

system, your dealer can supply the required “T” tting.

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

ination 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’s side

door for maximum loads listed for your vehicle.

When inating your Air Helper Springs, add air pres-

sure in small quantities, checking pressure frequently

during ination. The air spring requires much less air

volume than a tire and, therefore, inates much quicker.

WARNING:

Do not inate this assembly when it is

unrestricted. The assembly must be restricted

by the suspension or other adequate

structure. Do not inate beyond 100 psi

Improper use or over ination may cause

property damage or severe personal injury.

STEP 1 – PREPARE THE VEHICLE With the vehicle on a solid, level surface, chock the front wheels. Raise the vehicle by the rear axle and set on jack stands rated for your vehicles weight. Remove the real wheels. Remove the jounce bumpers from the under side of the frame rail. The jounce bumper will not be re-used with the kit, but the bolt will be re-used. STEP 2— ATTACH THE UPPER BRACKET Select one air helper spring and one upper bracket from your kit.

STEP 8— CHECK THE AIR SYSTEM Once the inflation valves are installed, inflate the air helper springs to 70 psi and check the fittings for air leaks with an applied solution of soap and water. If a leak is detected at a tubing connection then check to make sure that the tube is cut as square as possible and that it is pushed completely into the fitting. The tubing can easily be removed from the fittings by pushing the collar towards the body of the fitting and then pulling out the tube.

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.

TROUBLE SHOOTING GUIDE Air spring will not inflate Ensure that the air line tubing is inserted into the air fittings as far as possible. The tubing should go in the fitting 3/4 of an inch. You will feel some resistance when the tubing goes past the o-ring. Clear any dirt of debris from inside the inflation valves.
