About This Product
Keeping your primary chain at the correct tension is vital for smooth shifting and preventing premature wear on your drivetrain components. This primary chain adjuster kit from MCS is a complete solution for older Ironhead and early Evolution Sportsters. It is a direct replacement for OEM part number 39967-77A and is sold as a kit to make your maintenance task straightforward. This kit is designed to fit 1977 to 1985 XL Sportster models. Replacing a worn or notched adjuster will significantly improve the feel of your primary drive and help quieten down the mechanical noise from the primary case.
Manufacturer part number: 997555.
