Cometic C9844-NH EST Twin Cam Top End Gasket Kit Without Head Gasket

The Cometic C9844-NH is a comprehensive EST (Extreme Sealing Technology) top end rebuild kit designed for Harley-Davidson Twin Cam 95ci and 103ci engines from 1999-2017. This version of the kit includes all necessary gaskets, seals, and O-rings for a complete top end rebuild from the cylinder base up to the rocker boxes—except the head gasket, which is sold separately for customers who prefer to purchase it independently.

Key Features:

• Extreme Sealing Technology (EST) proven through state-of-the-art research and development
• Includes cam cover gaskets, rocker cover gaskets, intake and exhaust gaskets, valve stem seals, and all necessary O-rings
• Rocker cover gaskets feature embossed stainless spring steel coated with nitrile butadiene rubber (NBR)
• Cam cover gasket made from aluminum foam material (AM) bonded to aluminum base sheet
• Umbrella valves, intake seals, and O-rings manufactured from either Viton or NBR for superior durability
• 3.875" bore size specification
• No drain back O-rings required
• Made in the USA

This kit provides everything needed for a professional-quality top end rebuild when paired with separately purchased head and base gaskets. Cometic's EST gaskets are engineered to meet or exceed OEM specifications and are validated on both street and track applications.
