Bilstein B8 Performance Plus dampers are a performance upgrade to OE dampers designed to be paired with aftermarket lowering springs.

These dampers offer application-specific valve settings with a monotube design to bring out the best handling performance of a vehicle. Each damper is rigorously tested for quality that meets or exceeds OE standards. B8 Performance Plus dampers are the ideal solutions for pairing with a lowering spring for improved handling and sportier look with the added benefit of world-famous Bilstein quality.

Gas Pressure Technology. Over time, the mono-tube gas pressure technology developed by BILSTEIN has established itself as a standard in automotive construction. This technology involves keeping the oil in the absorber under pressure, which prevents it from foaming when temperatures and loads are increasing. As a result, full damping power is retained even when the system is placed under extreme stress, a feature that can be observed in the self-lowering piston.

Mono-tube Upside-Down Technology. The original and best: The original mono-tube gas pressure shock absorbers bore the BILSTEIN name, and we’re still responsible for producing the best there is. BILSTEIN’s mono-tube technology is the number-one choice in motorsports and series-production sports cars: no other type gives engineers the same freedom to choose the perfect installation location or position (e.g. Upside-Down technology).
