Derby Cover Gaskets/seals

19 products

Derby Cover Gaskets and Seals for Harley-Davidson prevent oil leaks from the primary cover derby plate on Big Twin models. Every time you inspect your clutch or change primary oil, the derby cover gasket should be replaced to ensure a clean, leak-free seal. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, supplies derby cover gaskets from James Gaskets and Cometic. Available for Twin Cam, Milwaukee-Eight, Evolution and Shovelhead primary covers, these gaskets and O-rings are made from oil-resistant materials that maintain their seal under the heat and vibration of a running V-twin engine. A fresh gasket is a small investment that prevents messy oil drips. Browse the full range below.
