Cometic C10037 MLS Head Gasket Bore Thickness - 3-13/16 040 Pair

The Cometic C10037 is a high-performance Multi-Layer Steel (MLS) head gasket pair designed for big bore Harley-Davidson Shovelhead engines. This gasket features a 3-13/16 inch bore diameter and .040 inch compressed thickness, specifically engineered for Shovelhead big bore applications from 1966-1984.

Multi-Layer Steel Construction:

• Comprised of multiple embossed layers of proprietary high temperature coated and uncoated stainless steel, requiring less clamp load and creating less bore distortion
• Utilizes LCE (Load Control Embossments) to promote even torque load across the gasket sealing surface, providing better piston ring seal for more power
• Outer layers are embossed and coated on both sides with Viton to meet the demands of harsh sealing environments
• Embossed outer layers meet the demands of a variety of load conditions and surface finishes

Key Specifications:

• Bore Size: 3-13/16 inches (3.8125")
• Compressed Thickness: .040 inches
• Material: Multi-Layer Stainless Steel with Viton coating
• Sold as a pair (two gaskets included)
• Made in the United States with materials manufactured on American soil

This gasket is ideal for builders looking to upgrade their Shovelhead big bore engines with race-proven sealing technology. The MLS design provides superior sealing performance compared to traditional composite gaskets, making it suitable for both street and performance applications.
