This component is a necessary replacement item for anyone refreshing or completely overhauling a classic 4-speed Ironhead Sportster transmission back to reliable running order.
  • Condition: Used, excellent condition. Splines and gear teeth show sharp profiles with minimal wear, and the drive dogs have clean, unrounded edges.
