Cometic Derby Cover Gaskets/seals

6 products — part of all Derby Cover Gaskets/seals

Cometic derby cover gaskets and seals for Harley-Davidson prevent oil leaks from the primary derby plate on Big Twin models — the flat cover on the outer primary that provides access to the clutch adjustment. Every removal and refitting of the derby cover is an opportunity for the gasket to fail, and a poor-quality seal will weep primary oil across the lower engine after only modest heat cycling. Cometic is respected across Harley-Davidson engine building for producing multi-layer steel and fibre gaskets that maintain their crush and sealing properties across repeated thermal cycles. Their derby cover seals are die-cut to OEM profiles and made from materials that resist primary oil and the temperatures generated within the primary chaincase.
