100% New Manufactured — Know the Difference!
Learn how the quality of BILSTEIN 100% new-manufactured B4 Air suspension modules differ from other products available on the independent repair shop market.
High-quality BILSTEIN B4 Air suspension modules are engineered and manufactured to uncompromising OEM standards. These new-manufactured components have only been available for a few years, offering a superior solution to a market flooded with reduced-functionality spare parts and poor quality remanufactured parts. BILSTEIN B4 air suspension modules are the only aftermarket solution that provides full functionality for all active and passive systems – delivering the same perfect driving experience and ride quality as when the car rolled off the lot.
Active air suspension modules such as the BILSTEIN B4 Air empower the driver with the option to switch between different driving modes. In extreme situations, for example an evasive maneuver to avoid a collision, the system automatically switches the ride characteristics to a more responsive and safe setting. After the maneuver, the system returns to the pre-selected driving mode. Retaining this functionality is paramount to a perfect driving experience – something only BILSTEIN can assure.
BILSTEIN B4 Air suspension includes 100% brand new components:
– NEW air spring
– NEW gas-pressure shock absorber
– NEW electromagnetic control valve
– NEW seals, sensors and electrical
What is remanufacturing?
For many vehicle components, remanufacturing (the reworking of old parts) is a reasonable and cost-saving alternative to new parts. This only applies if all the individual wear components are replaced. With air suspension modules, all components are subjected to wear:
Air bags wear due to contraction, extension, pressure and temperature.
Gas-pressure shock absorbers wear due to continuous movement and high mileage.
Electromagnetic control valves and seals wear due to continuous oil flow.
In remanufactured products, only the air spring is replaced, all other parts are reused. This means you have no way of determining how high the mileage of the donor shock absorber was run. With used donor shock absorbers potentially coming from different vehicles, it is possible that the damping force at the individual wheels will differ significantly.
With competitor products, the electromagnetic control valve is replaced with a resistor to deceive the OE electronic controls – defeating the functionality of multiple driving modes. The air suspension system becomes limited to one driving mode – a compromised solution. By installing a seemingly cheaper part, you remove functionality of your customer’s suspension and risk reducing driver safety.
In contrast to OEM or BILSTEIN B4 air suspension modules, remanufactured air springs use a cross-ply bellows system – requiring a significantly higher rolling radius. Since the working chamber remains the same size, the cross-ply bellow is subjected to a significantly higher level of wear – it cannot expand and collapse sufficiently. A cross-ply bellow system does not achieve the same sensitive spring response behavior as a BILSTEIN axial bellows system.
When servicing or replacing your air suspension, ask for BILSTEIN B4 Air and rest assured that safety, comfort, functionality and handling quality will be preserved.
