King 2.5" OEM Replacement Rear Shocks for 2005+ Ford Super Duty F250 / F350 / F450 / F550 4WD
King OEM performance kit custom tuned to provide your Ford with unparalleled levels of performance and ride quality. Each kit has been subjected to punishing real world testing to develop the optimal damping curve and spring rate for your vehicle. Easy bolt-on installation for stock height or custom kits for trucks running lifted aftermarket suspensions.
Built with race winning design features King's kits come complete and provide simple 100% bolt on installation with no cutting or welding done to your vehicle. King's Front kits provide an adjustable ride height and up to a 25% increase in wheel travel. Rear kits typically allow a 15% travel increase. Large 2.5" diameter Shock bodies and external Reservoirs dramatically increase fluid capacity and heat dissipation to provide sustained damping performance even under the most punishing conditions. King's OEM upgrade Shocks feature the same serviceable design that allows for valve adjustments with simple hand tools just like King's race Shocks.
King kits are available ready to bolt into stock vehicles or with custom lengths for vehicles running lifted aftermarket suspensions. Once you ride on Kings you will know there really is a difference. Nothing rides like a King.
- King's new adjustable shocks give you more off-road control by affecting your high-speed compression. Each of the twenty levels of adjustment offers precise compression damping control ranging from very soft to very firm.
- King specializes in custom application shocks. Most shocks can be made for custom fitment.
- Shocks fit stock height vehicles
