Cometic C10083-040 MLS Head Gasket 3.937" Bore x .040" Thick

The Cometic C10083-040 is a Multi-Layer Steel (MLS) cylinder head gasket featuring a 3.937" bore and .040" thickness, designed specifically for high-performance Harley-Davidson Twin Cam applications including 103" engines and larger displacements.

Advanced MLS Construction:

• Center shim layer uses uncoated stainless steel that can be varied to accommodate multiple thickness requirements, while outer layers are embossed and coated on both sides with Viton
• MLS design promotes even torque load across the gasket sealing surface utilizing LCE (Load Control Embossments), providing less bore distortion and better piston ring seal
• Quality materials developed for maximum performance tolerances and longevity to meet the demands of harsh sealing environments, load conditions, and surface finishes
• No re-torque necessary after installation

Sold as a pair to service both cylinders. Made in the U.S.A. Perfect for engine rebuilds, performance upgrades, or compression ratio adjustments on Twin Cam motors.
