Frequently Asked Questions
It is cataloged for Harley-Davidson Big Twin platforms: Panhead, Shovelhead, and Evolution Big Twin engines. Always confirm exact fitment by engine family, displacement, and year using a current Cometic or distributor fitment guide.
No. It is an aftermarket seal produced by Cometic Gasket as a replacement for the OEM Harley-Davidson engine seal used on Big Twin Panhead, Shovelhead, and Evo engines.
C9493 is listed as a single Cometic seal. Many full Cometic engine or top‑end kits include this or similar seals, but this SKU itself is for the individual seal.
No. C9493 is specifically cataloged for Panhead, Shovelhead, and Evolution Big Twin engines only. Twin Cam and Milwaukee‑Eight require different seals and gasket sets.
Cometic generally designs its gaskets and seals to work dry or with light oil where specified. Use sealant only if your service manual or Cometic’s application notes explicitly call for it for that joint.
