Bilstein and R-Customs have reissued ‘steel conversion’ kits

Bilstein explains it is possible to convert original air or ABC suspension systems to steel spring suspension systems for Mercedes-Benz W220 and C215.
Many of these models were already equipped with air or ABC (Active Body Control) suspensions during their production period (1998–2005).
At the end of their technical service life, Bilstein explains the air suspensions (Airmatic) now tend to leak and suffer compressor damage.
Although these repairs are technically manageable, the suspension manufacturer states they often fail due to poor availability of original spare parts.
Bilstein states the situation is much more critical with ABC suspension systems, which are designed to suppress roll movements during acceleration, braking, or fast cornering.
This complex electro-hydraulic system is prone to loss of hydraulic oil and frequent electronic faults in the control system.
In addition to the W220 model series, this also affects the CL C215 coupé variant based on the same platform, which was delivered ex-factory exclusively with ABC suspensions.
In cooperation with the Bilstein Customisation Programme (KSW), Bilstein and R-Customs have reissued a repair solution which they say impresses with an exceptional price/performance ratio, where the components of the air or ABC suspension are replaced with steel suspension or mechanical components.
R-Customs offers complete conversion kits for the Airmatic or ABC versions.
In addition to the Bilstein B12 complete suspension, which has been specially adjusted for the W220 and C215 models, the ABC version also includes mechanical stabilisers (radius rods) and coupling bars.
Both kits also contain deactivation modules for the on-board electronic system.
Bilstein says these conversion kits not only offer a durable and cost-effective repair alternative, but also provide additional benefits that are particularly important for lovers of modern classic cars:
• The conversion complies with the standard of the S-Class models with steel suspension at that time. Thus, the car becomes an “original steel” model, which will enable it to obtain an H registration plate also, in the future. Comfort and driving characteristics are at the level of the S-Class at that time.
• A parts certificate already allows for problem-free entry in the vehicle documents.
• Long-term value retention and resale potential of the car are guaranteed, as only OE-quality components are used and there will be no need for expensive suspension repairs in the future.
The kits enabling the conversion of the W220 and C215 to the new steel class can be ordered from R-Customs at https://r-customs.onepage.me/mercedes-abc
The conversion should only be carried out by a specialist workshop or a suitably experienced person.
