Cometic C9897 MLS Head Gasket Bore Thickness - 4.250 027

The Cometic C9897 is a high-performance Multi-Layer Steel (MLS) head gasket designed for Harley-Davidson V-Rod motorcycles with a 4.250 inch bore diameter and .027 inch compressed thickness. This precision-engineered gasket delivers superior sealing performance for high-performance and modified engines.

Key Features:

• Multi-Layer Steel construction with three layers for maximum sealing reliability
• Two outer embossed spring steel layers with Viton coating for extreme temperature and chemical resistance
• Uncoated stainless steel center layer provides structural support and can accommodate various thickness requirements
• Load Control Embossments (LCE) promote even torque distribution across the sealing surface
• Reduces bore distortion and improves piston ring seal for increased power output
• Premium fuel-resistant materials that will not creep, crack, or become brittle
• Manufactured in the USA from American-sourced materials

Cometic's MLS technology is ideal for high-performance applications where extreme cylinder pressures and temperatures demand a gasket that can withstand harsh sealing environments while maintaining consistent compression. The Viton-coated embossed layers conform to surface finishes and provide excellent resistance to oil, fuel, and coolant.
