The monotube shocks feature a 46mm digressive piston with self-adjusting deflective disc valving. Benefits of the reservoir include increased cooling capacity and increased shock travel. (zinc-plated steel body, Triple-C-Technology coating )Bilstein B8 5165 Series shocks offer a universal fit, with the benefits of a remote reservoir.
