Cometic C5989-060 AMC Inline MLS Cylinder Head Gasket Thickness - 4.0L 6 060

The Cometic C5989-060 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered for AMC 4.0L inline 6-cylinder engines. This precision-manufactured gasket features a .060-inch compressed thickness and is designed for a 4.060-inch bore diameter, providing superior sealing capabilities for both stock and modified applications.

Key Features:

• Multi-Layer Steel (MLS) construction for enhanced durability and sealing performance
• .060-inch compressed thickness provides optimal compression and sealing
• 4.060-inch bore diameter designed specifically for AMC 4.0L inline 6 engines
• Superior heat resistance and combustion seal compared to traditional composite gaskets
• Accommodates cylinder head and block movement from thermal expansion
• Ideal for high-performance, forced induction, and turbocharged applications

Cometic MLS gaskets feature multiple layers of stainless steel with an embossed viton rubber coating that ensures maximum sealing around combustion chambers, coolant passages, and oil galleries. The flexible design allows the gasket to conform to imperfect sealing surfaces while maintaining consistent clamping pressure across the entire head surface.
