Cometic C10083-040 MLS Cylinder Head Gasket 3.937 Bore .040 Thickness

The Cometic C10083-040 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket designed for select 2014-2016 Harley-Davidson Twin Cooled touring models and trikes. Engineered with a 3.937-inch bore diameter and .040-inch compressed thickness, this gasket delivers superior sealing performance in demanding V-twin applications.

Advanced MLS Construction:

• Three-layer design with uncoated stainless steel center shim layer for precise thickness control
• Outer layers embossed and coated on both sides with Viton for heat resistance and durability
• Load Control Embossments (LCE) promote even torque distribution across the sealing surface
• Reduces bore distortion for improved piston ring seal and increased power output
• Viton coating withstands harsh sealing environments, extreme temperatures, and varying surface finishes

Key Benefits:

• Designed for Twin Cooled engines but retrofits to air-cooled heads and cylinders
• Multiple embossed stainless steel layers provide exceptional strength and rebound characteristics
• Corrosion-resistant construction ensures long-term reliability
• No sealants required for proper installation
• Made in the USA with precision manufacturing tolerances

This gasket is sold as a pair and is ideal for engine rebuilds, performance builds, or replacing worn OE gaskets on compatible Harley-Davidson motorcycles.
