PARTS LIST

INSTALLATION INSTRUCTIONS

Congratulations - your new air helper springs are quality

products capable of improving the handling and com-

fort of your vehicle. As with all products, proper installa-

tion 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 spring kit is, of course, the air

helper 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 right or

passenger’s side of the vehicle. To install the left side

assembly simply follow the same procedures.

This kit includes ination valves and air lines for

each air spring. This will allow you to compensate for

unbalanced loads. If you would rather have a single

ination valve system to provide equal pressure to both

air springs, your dealer can supply the optional "T" t-

ting.

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 pres-

sure 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 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.

NOTE: THE JOUNCE BUMPER CUP STAYS ON THE FRAME AFTER THE JOUNCE BUMPER IS REMOVED. THE UPPER BRACKET FITS AROUND THE JOUNCE BUMPER CUP. NOTE: TALL LEG FACES TOWARDS FRONT OF VEHICLE! The INSERT must be pushed into the jounce bumper cup and then twisted into place to capture the flanges on the inside of the cup. See Figure “B”.

NOTE: Please read thorough this manual completely before installing the air spring kit to your vehicle. A heat shield is required on the exhaust side of the vehicle as noted in Step 4. If your truck has an aftermarket dual exhaust system, you may have to order an extra heat shield.

STEP 6 — 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. Using a spray bottle, apply a solution of soap and water to the fittings. If a leak is detected at a airline tubing connection then check to make sure that the airline is cut as square as possible and that it is pushed completely into the fitting.

COMBO STUD NOTICE: THE ALIGNMENT PIN ON THE AIR SPRING MUST BE INSTALLED INTO THE HOLE IN THE UPPER BRACKET. FAILURE TO DO SO WILL CAUSE THE ALIGNMENT PIN TO BE PUSHED INTO THE BEAD PLATE, CREATING AN AIR LEAK, AND RESULTING IN AN AIR SPRING FAILURE THAT IS NOT WARRANTABLE.

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 9
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.
