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.
OE wheel backspacing is NOT compatible. Wheels must have no more than 4.75-inch backspacing; the instructions identify 37x12.5 as the largest tire clearing the hose/reservoir with that backspacing, subject to a full installer clearance check. Diesel trucks require 2–2.5-inch lift springs or spring spacers; Bilstein names spring kit 53-317308. Only non-Tremor configurations are offered here: the catalog’s Tremor-relative lift note is not reconciled to the instruction baseline.
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.
