These kits offer dampers and springs that are tuned for each specific application to provide the best fixed height lowering solution. Bilstein B12 (Pro-Kit) suspension kits provide the perfect combination of suspension dynamics, quality and aesthetics.

B12 suspension kit is the go-to option for a sporty suspension upgrade. Developed specifically for your vehicle, the B12 is engineered for ease of installation and tailored to the ride dynamics of your suspension. 

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!
