Cometic C9726-034 HD Twin Cam Head Gasket Set 4 Bore .034 Thickness

The Cometic C9726-034 is a premium heavy-duty head gasket set designed for Harley-Davidson Twin Cam engines with 4-inch bore cylinders. This 2-pack features Cometic's proven Multi-Layer Steel (MLS) construction with a compressed thickness of .034 inches, providing superior sealing performance and durability for high-performance and stock applications.

Key Features:

• Multi-Layer Steel (MLS) construction for maximum durability and heat resistance
• 4.000-inch bore diameter designed specifically for Twin Cam engines
• .034-inch compressed gasket thickness
• Stainless steel outer layers resist corrosion and provide excellent recovery properties
• Advanced combustion seal technology prevents leaks and maintains optimal compression
• Includes 2 head gaskets for complete engine rebuild
• Designed to handle high cylinder pressures in modified and stock engines

Cometic gaskets are engineered using Advanced Flexible Sealing (AFS) technology, which allows the gasket to conform to imperfect sealing surfaces while maintaining a reliable seal. This makes them ideal for both fresh rebuilds and performance applications where engine tolerances may vary. The MLS design distributes cylinder pressure evenly across the gasket surface, reducing the likelihood of head gasket failure even under demanding conditions.
