Product Description

The Bilstein 24-186537 B6 Rear Shock Absorber is a direct-fit replacement designed specifically for 2001-2004 Workhorse W20 and W22 motorhome chassis, as well as similarly configured Monaco Coach and Holiday Rambler RVs on the same platform. Built with Bilstein's proven B6 monotube technology, this rear shock delivers enhanced handling, improved ride quality, and greater stability compared to factory shocks, especially under load and highway cruising conditions.

Featuring a velocity-sensitive, digressive piston and nitrogen gas charge, this shock reacts instantly to changing road surfaces while minimizing fade and maintaining consistent damping performance. The durable yellow powder-coated finish helps protect against corrosion, and its vehicle-specific tuning ensures an optimized balance of comfort and control for heavy motorhome rear suspension applications. Bilstein backs this shock with a limited lifetime warranty, making it a reliable upgrade for OEM replacement or suspension refresh projects.
