990541 Spring, detent arm transmission

This transmission detent arm spring is essential for keeping your gearbox in the selected gear and providing that positive click during shifts. It is an OEM-style replacement for part number 34483-90, specifically fitting 1991 to 2003 5-speed XL Sportster models. A worn or broken detent spring can lead to missed shifts or the transmission popping out of gear, so replacing it during a primary or transmission service is a smart move. Built for long-term reliability, this spring ensures the detent arm maintains the correct pressure against the shift drum. It is a critical part for any 5-speed Sportster rider looking to maintain factory-spec shifting performance and prevent internal gearbox issues.
