The KONI Workhorse rear FSD shock for 1999–2003 W22 motorhome and truck applications is a twin-tube, non-adjustable hydraulic unit intended as a direct-fit replacement. It restores consistent damping behavior for rear axle loads and provides reliable hydraulic shock absorption for motorhome and light-truck service where OEM-style hydraulic tuning is required.
