519735 Mechanical brake drum dust ring

This mechanical brake drum dust ring from MCS is an essential part for maintaining the rear brake system on vintage Harleys. It is designed specifically for 1930 to 1959 FL models. The dust ring helps protect the internal brake components from road grime and debris, which is crucial for the consistent operation of mechanical drum brakes. This part is a direct replacement for OEM 41420-30. For restorers and riders of classic Panheads and Knuckleheads, keeping the braking system clean and well-sealed is a priority for both performance and safety. This ring ensures a proper fit and period-correct function.
