Installation and supporting components
Installation must be carried out by a qualified suspension technician using the linked Bilstein instructions. Confirm full bump/droop, hose, brake-line, tire, steering and reservoir clearances for the actual suspension, axle and wheel setup. A damper by itself does not create suspension lift.
Manufacturer quantity per vehicle: 2. Order the required matching units for the relevant position; do not treat this single item as a complete kit.
Suspension modifications can change handling and may be limited by local regulations. No universal road-legality or emissions-approval claim is made for this mechanical suspension item.
