Bilstein B12 Pro-Kit Suspension Kit for BMW 5 Series E39
Part Number: BILSTEIN-46-180841
Transform the way your BMW E39 drives with the Bilstein B12 Pro-Kit 46-180841. This complete suspension upgrade combines Bilstein B8 high-performance shock absorbers with Eibach Pro-Kit lowering springs for sharper handling, improved stability and a purposeful lower stance. Ideal for fast-road use, daily driving and a direct upgrade from tired standard or Sport suspension on the E39 5 Series.
Designed specifically for the BMW 5 Series E39, the B12 Pro-Kit delivers a precise, confident and sporty ride while maintaining everyday comfort. Expect crisper turn-in, reduced body roll, better high-speed composure and a great OEM+ appearance.
Why choose the Bilstein B12 Pro-Kit for your E39
- Matched system: Bilstein B8 performance dampers paired with Eibach Pro-Kit springs for optimal balance and control
- Lowering: typically around 10 to 30 mm depending on model and axle load for a clean, even stance
- Monotube gas-pressure technology for precise response and consistent performance
- Progressive-rate Eibach springs for comfort over small bumps and support in hard cornering
- Inverted strut design used on select applications for increased rigidity
- TUV approved for quality and safety
- Direct-fit upgrade engineered for BMW E39 chassis dynamics
Real-world results. We have installed this kit on E39s ourselves and customer feedback has been excellent, with a noticeable improvement in steering feel, cornering grip and overall ride quality compared with tired factory suspension.
Note on terminology: many owners search for BMW E39 coilovers. The Bilstein B12 Pro-Kit is a fixed-height performance suspension kit, not a height-adjustable coilover system. If you want OEM+ handling, reliability and the right drop without the complexity of height adjustment, the B12 Pro-Kit is a superb choice.
