Direct-fit OE upgrade front shock for 2003–2023 Chevrolet Express and GMC Savana full-size vans at stock height. Fits 2500, 3500, and 4500 series. 46mm monotube nitrogen gas design. Stud upper / cross pin lower mount. Made in the USA.
The Bilstein 24-187435 B6 4600 Series Front Shock Absorber is the direct-fit OE upgrade for the Chevrolet Express and GMC Savana full-size van platform — one of the most widely used commercial van platforms in North America. Covering the 2500, 3500, and 4500 series from 2003 through 2023, this shock serves an enormous range of applications: passenger shuttles, work cargo vans, Class C motorhome builds, fleet vehicles, upfitted service vans, and daily-use commercial vehicles.
The front end of a loaded Express or Savana takes constant punishment — carrying the weight of the engine, cab, heavy payloads, and the demands of urban stop-and-go mixed with highway travel. Worn front shocks on these vans show up as increased steering vagueness, front-end float, instability during emergency maneuvers, and driver fatigue on long runs. The 4600 series, precisely valved for this platform, restores and improves all of that without any lift or modification required.
Stud upper / cross pin lower — bolt-on front replacement at stock height using OEM mounting configuration
Fade-free front damping under sustained commercial van loads — consistent performance in fleet and heavy-duty use
Engineered for the real-world demands of cargo hauling, passenger transport, and loaded commercial van use
Designed, engineered, and manufactured in the USA. Backed by Bilstein's limited lifetime warranty
