Bilstein B8 6100 shock absorbers are filled with the technology perfected over 3 decades of off-road dominance. Bilstein's monotube gas pressure design with a large 60mm digressive piston maximizes heat dissipation for increased shock life, and decreases oil foaming to prevent performance loss while providing a smoother ride and more control over rough terrain. The B8 6100 will provide increased durability, making them perfect for vehicles subjected to rugged roads and harsh conditions.
