Direct-fit OE upgrade front shock for the full 1999–2004 first-generation Ford Super Duty lineup at stock height. Fits F-250, F-350, F-450, and F-550. 46mm monotube nitrogen gas design. 16mm upper / 12mm lower eyelet mounts. Made in the USA.
The Bilstein 33-028187 B6 4600 Series Front Shock Absorber covers the entire first-generation Ford Super Duty lineup — F-250, F-350, F-450, and F-550 — across the full 1999 through 2004 production run. This is a single part number for the entire platform, making it one of the broadest-coverage front shocks in Bilstein's Super Duty catalog.
The first-gen Super Duty was Ford's ground-up heavy-duty truck platform, built for demanding commercial and personal use. High-mileage front shocks on these trucks translate directly into vague steering, front-end float, reduced braking stability, and accelerated tire wear — particularly under the front axle loads of a loaded F-350, F-450, or F-550. The 4600 series restores all of that, delivering more precise front-end control, better stability under load, and the kind of composed highway feel that makes Super Duty trucks the standard for heavy-duty work.
One part covers all first-gen Super Duty models — F-250, F-350, F-450, and F-550 — from 1999 through 2004
Fade-free front damping under heavy commercial loads — consistent performance under the full range of Super Duty payloads
Application-tuned for the real-world demands of commercial trucks, farm haulers, and heavy-duty tow vehicles
Designed, engineered, and manufactured in the USA. Backed by Bilstein's limited lifetime warranty
