About This Product
These back-up rings for 39mm fork seals are a necessary component for any front-end rebuild, ensuring the fork seals stay properly seated and supported. Sold as a pack of ten, these rings are a direct replacement for OEM 45377-87. They fit a wide range of models with 39mm tubes, including 1987 to 1994 FXR models, 1991 to 2005 Dynas (excluding FXDWG), and 1988 to 2021 XL Sportsters. Note that they do not fit 2016-2021 XL1200X, 2016-2020 XL1200XS, or 2017-2020 XL1200CX Roadster models. Having a bulk pack on hand is ideal for the busy workshop, ensuring you always have a fresh spacer when refreshing the front suspension.
Manufacturer part number: 945387.
