Bilstein Monotube Rod Shocks Parts 4

Aside from the larger valve diameter, the larger piston gives Bilstein the area to run channels through the piston. On compression, oil flows from side one's OD slots to side two's ID slots where it deflects the plates. On rebound, oil from side two's OD slots flows to side one's ID, where it deflects more plates. Bilstein uses the low-drag Teflon strip (shown next to its piston on the right) as the piston ring. Note the light-colored ring at the shaft's top to protect the piston during hyperextension.
