The Bilstein Sport Shock is for the performance-minded enthusiast needing a damper designed to work with a more aggressively rated lowering spring. Bilstein Sports deliver absolute mastery of the road surface and are designed to push a car's suspension to its performance peak. In addition to being designed to work with lowering springs, these shocks are perfect for use with performance sway bars or an upgraded tire and wheel package. All Bilstein Shocks include a limited lifetime warranty from the manufacturer.
