AIR SUSP KIT 5-Series E39

The D2 Racing Air Struts with Optional Management (AR-BM-08-1-ARVEL) are air suspension systems designed for the 1999-2003 BMW 5 Series. This system allows for adjustable ride height and tunable shock performance. It features high-pressure air bags and 36-way damping adjustable internal shocks for comfort-to-firmness tuning. The adjustable lower mount enables fine-tuning of ride height at virtually any PSI. The system utilizes RS-Series shock quality with air-specific valving, where higher PSI results in a stiffer ride and lower PSI provides a softer ride. Damping adjustments are made by turning counterclockwise for softer and clockwise for stiffer settings. Various air management upgrade options are available, ranging from entry-level manual systems to advanced electronic systems with Bluetooth app control, offering enhanced control and monitoring capabilities.
