Cometic C5831-066 Chrysler Midget Block MLS Head Gasket Bore - A-4 4.165

The Cometic C5831-066 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chrysler A-4 Midget racing engines. This high-performance gasket features a 4.165-inch bore diameter and .066-inch compressed thickness, providing optimal sealing for modified and high-compression applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior sealing and durability
• 4.165-inch bore diameter for precise fitment
• .066-inch (1.68mm) compressed thickness for compression ratio tuning
• Engineered specifically for Chrysler A-4 Midget racing blocks
• Handles extreme cylinder pressures in high-performance applications
• Eliminates gasket failure common with composite gaskets in race engines

Cometic's MLS gaskets feature multiple layers of stainless steel with specialized coatings that allow the gasket to conform to imperfections in the head and block surfaces. This advanced design provides excellent recovery and rebound characteristics while maintaining consistent clamping pressure across the entire sealing surface, making it ideal for dirt track midget racing and other high-stress applications.
