Bilstein Performance B12 Pro-Kit

Bilstein B12 Pro-Kit suspension kits are a complete set of B8 Performance Plus dampers paired with Eibach Pro-Kit springs that provide moderate lowering between 24-40mm (depending on application). Lowering is quick and easy, and perfectly matched to your vehicle and your needs.

B12 Pro-Kits offer dampers and springs that are tuned for each specific application to provide the best fixed height lowering solution. The Bilstein B12 Pro-Kit performance suspension system is the perfect sport suspension upgrade for improved handling, quick and easy lowering, quality, and aesthetics.

Both sporty and comfortable? It’s possible! A Bilstein B12 Pro-Kit is the go-to option for a sporty suspension upgrade. Developed specifically for your vehicle, the Pro-Kit is engineered for ease of installation and tailored to the ride dynamics of your suspension. The B12 system provides improved stability for more performance and comfort – even on long-haul trips.

The spring compression height and motion ratio remain the same, just like your original suspension geometry. This means that ground clearance remains the same and nothing grinds or rubs!
