1. Stud
A permanent part of the bead plate assembly used to attach the airspring to the suspension.
2. Combo Stud
Combination mounting stud and air fitting.
3. Blind Nut
A permanent part of the bead plate assembly providing an alternate mounting system to the stud.
4. Air Fitting Hole
A tapped hole usually 1/4" N.P.T. providing air entrance for the part.
5. Bead Plate
Permanently crimped onto the bellows at the factory allowing complete part leak testing prior to shipment.
6. Bellows
The heart of an Airide spring. Includes at least four plies, or layers, of materialÐan inner layer, two plies of cord-reinforced fabric, and an outer layer.
7. Bumper (Optional)
A solid molded rubber fail-safe device used on many suspension applications. Prevents excessive damage to vehicle and suspension in the case of sudden air pressure loss.
8. Piston
The lower section of the 1T and 1X style of airspring made from aluminum, steel or fiber reinforced plastic. Provides lower mounting arrangement for the airspring in the form of tapped holes or studs.
9. Piston Bolt
Attaches the piston to the bellows assembly. Extended, in some cases, to serve as a means of attaching the spring to the suspension.
10. Girdle Hoop
A ring between the convolutions of the convolutedtype air spring.
Removal Warning
Vent all air pressure from the air suspension system prior to disconnecting or removing any air suspension components. It is dangerous to remove air suspension components while under pressure. Failure to follow this instruction may result in serious personal injury.
Any air spring which is unfolded must be refolded prior to being installed in a vehicle. Refer to the procedure. An incorrectly folded air spring could rupture, altering the handling characteristics of the vehicle. If a vehicle has been driven with an incorrectly folded air spring, a new air spring must be installed. Failure to follow these instructions may result in serious injury to vehicle occupant(s).
Failure to observe the following instructions may result in a sudden failure of the air spring or suspension system.
Any rear spring which is unfolded must be refolded prior to being installed in a vehicle.
The air spring refolding procedure should only be used for an air spring which has never supported the vehicle's weight while in the incorrectly folded position.
Incorrectly folded air springs found on vehicles during pre-delivery inspection or after use must be installed new.
Do not attempt to inflate any air spring which has been collapsed while uninflated from the rebound hanging position to the jounce stop.
When installing a new air spring, care must be taken not to apply a load to the suspension until springs have been inflated using the air spring fill procedure.
After inflating an air spring in the hanging position, it must be inspected for correct shape.
Note
1 year warranty for any manufacture defect.Please provide photos or videos to apply for warranty.
Please inspect this part carefully prior to installation and contact us with any questions before attempting to install it.
The vehicle must be positioned on a suitable lifting device prior to deflating the air suspension system.
With the vehicle in NEUTRAL, position on a hoist until the wheel and tire assemblies are slightly above the ground.
2.Using the scan tool, vent the air springs.
3.Remove the air spring retainer.
4.Detach the air spring from the rear axle.
5.Remove the air spring in the following sequence.
1.Disconnect the air spring solenoid electrical connector.
2.Compress the quick connect locking ring and pull out the air tube.
3.Remove the air spring.
Frequently Asked Questions
How to prevent the damage of air springs/How to extend the service life of air springs/struts etc.?
An air strut with separable air springs
If your vehicle offers a separable air suspension (Audi Allroad A6 C5, Mercedes-Benz W164, BMW X5, etc.), you should regularly (about once a week) lift the car to the maximum position, and remove dirt with a high-pressure cleaner (keep the cleaner at a distance to the air spring about 30 cm/12 inches, otherwise water pressure can damage the air spring). The highest position may vary depending on your model and regulation options. Therefore, please test this by trying the different modes available to you (Sport, comfort, dynamic, off-road) and choose the one that sets your vehicle to the highest position. The dirt will most likely be found under the fold of the pneumatic chambers. If you find a frozen layer of bitumen on the piston guide (the part of a strut on which the air spring is installed), it is recommended to clean it as well. Whenever possible, avoid riding on fresh asphalt, as fresh bitumen mixed with sand immediately results in a build-up of abrasives on the piston and in turn contributes to accelerated wear and tear of the air spring.
A complete air suspension shock
Many cars such as Mercedes W220 or W211 are set up with a complete air strut - shock absorber and air spring visually form a complete spare part. In many cases, you can easily recognize these by the metal cups with which the air spring is tightly mounted. To best avoid any damage, we highly recommend to regularly check the condition of the dust protection seals of the air strut.
What is the difference between an air spring and an air strut?
The air spring is a part of the air strut. Some vehicles (e.g. Mercedes ML) allow you to change the air spring separately. At our online shop you have the opportunity to buy either the whole air strut or only the air spring. For some type of vehicles it is not possible to change the air spring separately. In this case the whole air strut should be replaced.
Which side of my car is the Right and Left?
The right and left sides of an automobile are determined as if sitting in the car facing forward. Thus, the left side is on the left when sitting in the car facing forward, and the right side is on the right. For American cars, the driverÕs side is on the left, and the passenger sits to the right of the driver. For cars in Japan, Britain, Ireland, the Bahamas and some other former British colonies -- where they drive on the left side of the road -- the passenger sits on the left side, and the driver (along with all the driving controls) is on the right.
