Like being on cloud 9 – BILSTEIN B4 air suspension module now available on the independent aftermarket

Trading Start of BMW Air Suspension Modules in the Aftermarket

Ennepetal, October 19, 2011 – Trading start for BILSTEIN’s air suspension module to the independent aftermarket is in October. With the introduction of the air suspension modules for the BMW 7 Series E65 and E66, BILSTEIN is expanding its product portfolio, which currently includes air suspension modules for Mercedes Benz. BILSTEIN is then planning to expand its product offering soon, as other premium applications are in the pipeline.

With the development of a BILSTEIN B4 air suspension module for the BMW 7 series E65 and E66, BILSTEIN has responded to the increasing market popularity of air springs. The high performance BILSTEIN B4 air suspension module is now also available to the independent aftermarket thanks to BILSTEIN transferring its OE competence to the aftermarket. To begin with, the air suspension module will be produced only for vehicles with leveling on the rear axle and for passive shock absorbing systems.

In addition to offering OE quality, the numerous product benefits are obvious. Just like the OE product, the BILSTEIN B4 air suspension module guarantees quickest ever reactions to road and vehicle conditions. The result is excellent comfort and perfect driving characteristics, with high power reserves for maximum safety. The BILSTEIN gas pressure technology provides constant damping power under any axle load.

Air suspension systems allow you to adjust to different vehicle height positions by varying the air pressure in the bellows. This advantage is particularly notable when leveling all kinds of loads. Various aerodynamic and terrain positions are also possible.

Original equipment quality is in demand in the aftermarket: The launch of the BMW 7 series BILSTEIN B4 air suspension module is also the starting shot for an entire range. BILSTEIN is planning to introduce additional part numbers for applications in the premium segment over the coming months. The high quality air suspension modules will all be produced and tested to OE specifications, including the usual endurance and cold-impact tests. "We occupy a unique market niche. There are currently no competing products on the market apart from the original series spare parts of the vehicle manufacturer. This makes the BILSTEIN B4 air suspension module unique", says Dirk Everding, Director Production & Development at BILSTEIN.

The technical concept is based on a modular system which can be used as the basis for the new development of future BILSTEIN B4 air suspension module applications. BILSTEIN engineers have subjected the shock absorbing system to road trials in Papenburg to ensure that it complies with OE series standards. The air suspension module was intensely checked at the test center there. Backed by extensive adjustment drives, BILSTEIN now offers its customers production-like premium class driving comfort with that special BILSTEIN driving feeling.
The shock absorbers are produced at BILSTEIN’s Ennepetal plant in Germany in a production area specially created for this purpose, by dedicated personnel assigned for this work. The expansion of this innovative product segment is strategic; investments in the location thus include the establishment of new assembly and material areas, a new leak testing facility and final assembly packaging.

This is a new business segment that BILSTEIN engineers have explored. "We recognized early on that the air suspension business is expanding strongly. True to our policy of "Engineered & Made in Germany", our aftermarket product developers got together with their colleagues from original equipment to tackle the task of coming up with product that offers series replacement the same benefits as an original equipment air suspension", according to Dirk Everding.

Editorial note:
The development of the BILSTEIN B4 air suspension module for the BMW 7 series brings to the independent aftermarket a suspension technology which BILSTEIN engineers originally developed jointly with Mercedes-Benz. The Mercedes-Benz S-Class (W220), for example, owes its legendary driving comfort to the BILSTEIN B4 air suspension. BILSTEIN currently produces active air suspension modules for the E and M class, as well as for the Jaguar XJ. Air suspension modules that BILSTEIN developed with Land Rover are used in its Discovery and Range Rover Sport models because of their performance in difficult off-road terrain.
