Direct-fit front OE upgrade shock for 2005–2009 Workhorse W20, W22, and W24 Class A motorhome chassis. Also fits Holiday Rambler and Monaco Coach coaches on the same platform. 46mm monotube nitrogen gas design. Made in the USA.
The Bilstein 24-153249 B6 4600 Series Front Shock Absorber is a direct-fit upgrade for Class A motorhomes built on the Workhorse W20, W22, and W24 chassis from 2005 to 2009. These are large, heavy coaches — many over 30 feet — and the front shocks bear constant load from the cab, engine, front cap, generator, and the cumulative weight of a fully loaded motorhome. Worn front shocks on a motorhome of this size translate directly into reduced steering response, excessive front-end float, and driver fatigue on long highway runs.
Bilstein's 46mm monotube design, tuned specifically for the Workhorse W-Series chassis, replaces that compromised handling with real front-end control — absorbing road inputs before they reach the cab, stabilizing the motorhome through lane changes, and providing the settled, confident feel that makes cross-country driving pleasant rather than exhausting.
Application-valved for the W-Series Class A chassis — not a generic heavy-duty truck shock
Consistent, fade-free front damping under the sustained loads of Class A motorhome travel — highway and off-road
Self-adjusting velocity-sensitive piston reacts instantly to road conditions for smooth, controlled front-end response
Designed, engineered, and manufactured in the USA. Backed by Bilstein's limited lifetime warranty
