About This Product
This MCS one-piece rubber compensator isolator is a direct replacement for the factory sprocket isolator on 2021 to 2026 Sportster S, Nightster, and Pan America models. It is designed to meet the same standards as OEM part number 42200212, ensuring a proper fit in the rear wheel assembly. As a critical maintenance item, checking this isolator for play is essential for smooth power delivery. It is a smart idea to keep one of these on hand and swap it out during a routine tyre change to keep your drivetrain tight and prevent unnecessary wear on your components.
Manufacturer part number: 917623.
