Replacing or removing your Harley-Davidson derby cover? Make sure you have the correct derby cover gasket or O-ring seal for your motorcycle.
American Freedom offers replacement Harley-Davidson derby cover gaskets and seals for a wide range of Harley models and years, including Touring, Trike, Softail, Dyna and Sportster motorcycles.

Which Harley Derby Cover Gasket Do I Need?
The correct derby cover gasket depends on the year, model and derby cover configuration of your Harley-Davidson.
Some motorcycles use a traditional derby cover gasket, while newer applications may use an O-ring style derby cover seal. Harley-Davidson has also used different profiles and sizes depending on the motorcycle and model year.
Always check the individual product description and fitment information before ordering to make sure you’re selecting the correct gasket or O-ring for your motorcycle.
If you’re unsure which one you need, contact us with the year and model of your Harley-Davidson and we’ll help you determine the correct derby cover seal.
Replacement Gaskets for Stock & Custom Derby Covers
A proper seal is important whether you’re reinstalling your factory Harley-Davidson derby cover or installing one of our custom American Freedom derby covers.
If you’re replacing your derby cover and the existing gasket or O-ring is damaged, flattened or otherwise needs replacement, it’s a good time to install a new seal before reassembly.
American Freedom carries derby cover gaskets and O-ring seals for Harley-Davidson motorcycles so you can order the correct seal along with your custom derby cover.
