Bitubo WMB0 331mm Chrome Edition Twin Rear Shocks for 1917+ Harley-Davidson - HD004WMB03

The Bitubo WMB0 twin-shock package, part number HD004WMB03, is a rear-suspension replacement and upgrade for 1917+ Select Harley-Davidson Models. The setup combines spring preload, length adjustment, a 331 mm length and Chrome Edition finish. It replaces aging factory damping with a purpose-built Bitubo component while adding the adjustment range specified for this exact part. That gives you a more useful setup window for matching the chassis to rider weight, load, and intended use instead of being locked into a one-setting stock suspension package.

About Bitubo WMB0 Twin-Shock Series:

The Bitubo WMB family is a nitrogen-pressurized twin-shock platform for classic, custom, modern-classic, and selected scooter applications. The WMB0 version uses standard-length twin shocks with continuous spring-preload adjustment, making it a clean upgrade when the goal is better matched rear support without adding unnecessary adjusters.

About Bitubo Suspension:

Founded in 1963, Bitubo develops motorcycle suspension and damping systems for street, racing, V-twin, scooter, Vespa, and off-road applications. Bitubo continues to design, engineer, develop, and manufacture its suspension products in Italy, drawing on decades of R&D and competition experience. For Elite Race Fab customers, it is the kind of hardware we like to see: purpose-built components, useful adjustment where the application calls for it, and a clear focus on getting the chassis working the way it should.
