For 1999-2004 Ford F-350 Super Duty 4WD (SRW)

Upgrade the rear suspension on your 1999-2004 Ford Super Duty with the Bilstein B6 4600 Series shock absorber (part #33-185347). This 46mm monotube gas-pressure shock is a direct-fit replacement for stock-height trucks that delivers noticeably better control, stability, and ride quality than OE dampers—whether you’re daily driving, towing, or hauling.

• Superior body control helps keep cargo secure and reduces sway
• Application-specific valving tuned for stock-height Super Duty trucks
• Yellow powder-coat finish with blue protective bellows for durability and heat dissipation
• Direct bolt-on installation using OEM-style mounting points (no modifications required)

• Compatible with 7.3L Powerstroke, 6.0L Powerstroke, 5.4L, and 6.8L engines
