577038 Sissy bar kit 21" 1-piece upright, chrome

This 21-inch chrome sissy bar kit from MCS offers a classic tall profile with the convenience of a modern quick-detachable design. Built with sturdy one-piece construction, it features side plates welded directly to the upright for maximum strength and a clean look. It is designed to fit 2004 to 2022 XL Sportster models, though it excludes 2016 to 2020 XL1200CX Roadster models equipped with a two-up seat. Installation is straightforward but does require model-specific docking points and a hardware kit, such as the 572171 kit. Whether you are looking for passenger security or a place to strap down your gear for a long trip, this chrome upright, identified by part number 577038, delivers that timeless chopper aesthetic with reliable functionality.
