Cometic C9182-030 EST Top End Gasket Kit 3.937in Bore .030in MLS Harley Twin Cam

The Cometic C9182-030 EST Top End Gasket Kit is engineered for Harley-Davidson Twin Cam engines from 1999 and later models with 3.937-inch (100mm) bore cylinders. This comprehensive kit features Cometic's proven Extreme Sealing Technology (EST) and includes a .030-inch compressed thickness multi-layer steel (MLS) head gasket for precision sealing.

Advanced EST Technology Features:

• Multi-layer steel (MLS) head gaskets with embossed stainless steel construction
• Proprietary rubber coating on head and base gaskets for superior sealing
• Steel Viton-coated base gaskets for exceptional heat resistance
• Blue Viton valve stem seals for long-lasting performance
• AFM (Aluminum Fiber Material) gasket components
• Race-style exhaust gaskets that resist fraying

Complete Top End Rebuild Kit: This kit contains all necessary gaskets, seals, O-rings, and washers needed to rebuild your Twin Cam top end from the cylinder base upward, including head gaskets, base gaskets, rocker box gaskets, intake manifold seals, and exhaust gaskets.

The MLS head gasket design allows heat to be drawn away from the combustion ring and dissipated evenly across the gasket surface, eliminating hot spots and preventing gasket failure. Ideal for big bore applications, performance builds, and complete top end rebuilds on 98ci or 107ci Twin Cam engines.
