About This Product
This MCS retaining ring is a specific replacement for the rear master cylinder piston on classic FL models. It is designed to fit 1941 to 1984 FL Big Twins, providing the necessary retention for the internal piston assembly. This ring is a direct replacement for OEM numbers 11063 and 590223. When you are rebuilding a vintage master cylinder, using a new retaining ring is essential for safety, as it keeps the hydraulic components properly seated under pressure. These are high-quality steel rings that offer the correct tension for a secure fit. They are sold as a pack of 10.
Manufacturer part number: 590223.
