Bilstein Motorsport Shock Absorbers offer the technology and performance necessary to keep serious competitors crossing the finish line first! The monotube design allows for a larger working piston with deflective disc valving, elminating the need for check valves and other componentry that result in consistencies in valving and variations in performance. Available in steel and aluminum bodies, both sealed and racer-rebuildable, for a wide range of applications from pure stock to NASCAR.
