The 2007-2013 BMW-Compatible X5 Rear Air Suspension Conversion Kit (BB2RB) is the perfect solution to your air suspension problems. Designed to be very affordable, you can convert your air suspension to use passive shocks and coil springs for less than the price of replacing one original equipment air spring.

Replaced Components
The 2007-2013 BMW X5 is built with the following suspension components: 2007-2013 BMW X5 Air Springs (x2)- commonly referred to as air bags, a plastic and rubber bag that is fitted on top of the strut that uses pressurized air as a cushion instead of a metal coil spring to hold a vehicle off of the ground and off of its wheels. These are the number one cause of all air suspension leaks. All air springs all go bad at about the same rate. If one is leaking, the others will not be far behind. For a proper repair, all of them need to be replaced at the same time. 2007-2013 BMW X5 Struts (x2)- on some 4x4 models. A type of shock absorber, it is a piece of metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle. 2007-2013 BMW X5 Air Lines- tubes that run from a compressor (air suspension) to the air struts which carry pressurized air to the air bags components in order to adjust the height of the vehicle, respectively. 2007-2013 BMW X5 Compressor- creates/sends pressurized to active suspension components. When the air suspension starts leaking, the compressor/pump starts working harder to try to keep the system inflated. By the time air suspension leaks down completely, sitting the vehicle on its tires, the compressor will either have failed or be well on its way to full failure. Buying replacement struts and taking the time to install them only to find out the compressor still needs to be replaced can be very frustrating, time-consuming, and expensive. 2007-2013 BMW X5 Dryer Assembly- used to keep moisture out of air lines and air springs in order to prevent freezing and internal cracking of these parts. Once air suspension starts leaking, moisture will build-up throughout the air system. Moisture damages the air suspension from the inside. The dryer will need to be replaced in order to eliminate the moisture and prevent any further damage. 2007-2013 BMW X5 Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicles correct ride height. 2007-2013 BMW X5 O-rings- Although they are the least expensive parts of the air suspension, they are responsible for maintaining the seal where all of the air lines connect. Be sure to replace the O-rings when repairing any air suspension system.

Suspension Failure Signs
If you notice your car has an uneven, changing, or unusual ride height, there is a chance you are dealing with a failed or leaking air suspension. There are specific indicators to look out for that will tell you if you need to repair a bad system. Sudden changes in ride height, in the front, back or either side, is the first sign. Sagging and leaning is something else to look out for. If you see a warning message or light on your instrument console, it could be a failed suspension. Your air compressor might also wear out if you are running on a leaking air suspension. A working air compressor is not noticeable- any noise or disturbance is a bad sign. Repair or replacement of a bad air suspension is important for overall vehicle maintenance.

OEM Replacement Cost
'+ Rear Air Struts ($469/strut) + Compressor and Dryer Assembly ($699) = TOTAL: Over $1,630 (and that doesnt even include replacing electronic components that are known to fail such as the height sensors).
Dealers and dealerships will charge a lot of money for a direct replacement or repair of your bad air suspension system. Our conversion kits boast a low price and convenience that cant be beaten.
