Direct-fit motorhome-specific front shock for 2001–2004 Workhorse W20 and W22 Class A chassis at stock height. Features Bilstein's Comfitrac® piston. Also fits Holiday Rambler Vacationer and Monaco Coach built on W20/W22. Eyelet upper and lower mounts. Made in the USA.
The Bilstein 24-186629 B6 4600 Series Front Shock Absorber is the front companion to the 24-186537 rear shock — together forming the complete stock-height Bilstein suspension upgrade for the Workhorse W20 and W22 Class A chassis (2001–2004). Front shock condition is critical to motorhome safety: worn front shocks increase steering vagueness, reduce stability in lane changes and crosswinds, and make the front end of a heavy Class A feel disconnected and unpredictable.
With Bilstein's Comfitrac® working piston — designed specifically for motorhome applications — this shock delivers the precise front-end control and high-frequency comfort that a full-size Class A motorhome demands. The result is better steering precision, dramatically reduced front-end float and sway, and the stable, confident handling that makes long highway trips safe and enjoyable.
Application-valved for the W20/W22 Class A front suspension — not a generic truck shock, but a dedicated motorhome upgrade
Bilstein's motorhome-specific piston design delivers superior high-frequency front-end comfort and steering stability
In addition to the base W20/W22 chassis, fits Holiday Rambler Vacationer and Monaco Coach La Palma and Monarch
Designed, engineered, and manufactured in the USA. Backed by Bilstein's limited lifetime warranty
