Cometic C15149-040 Chrysler Hemi MLS Cylinder Head Gasket Bore - 6.1L Gen-3 040 4.100

The Cometic C15149-040 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chrysler 6.1L Gen-3 Hemi engines. This high-performance gasket features a .040" compressed thickness and is engineered for a 4.100" bore diameter, providing optimal sealing for stock and modified engine applications.

Key Features:

• Multi-Layer Steel (MLX) construction for superior durability and heat resistance
• .040" compressed gasket thickness for precise compression control
• 4.100" bore diameter optimized for 6.1L Hemi applications
• Engineered to withstand extreme cylinder pressures and temperatures
• Stainless steel outer layers with elastomer coating for maximum sealing
• Designed for use with stock or performance cylinder heads

Cometic MLS head gaskets are manufactured using multiple layers of stainless steel, which provide the ability to rebound and seal surface imperfections better than traditional composite gaskets. This design makes them ideal for engines with increased boost, nitrous, or high compression ratios. The embossed sealing beads around combustion chambers, coolant passages, and oil passages ensure reliable sealing under extreme conditions.
