JIMS SPROCKET NUT SOCKET FOR SPORTSTER & BUELLThis short socket is designed specifically for XL models to remove, install and properly tighten the front final drive sprocket pulley. Although a similar tool for Big Twin will also fit the nut, the main shaft on Sportster models does not extend through for the guidance collar to ensure correct alignment. This shorter socket tool is easier and safer to handle, providing full contact to the nut. Fits all 1991 to present Sportster and air cooled Buell
