Cometic C5918-045 MLS Cylinder Head Gasket Chrysler LA Bore Thick - for V8 318 4.125 045

The Cometic C5918-045 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chrysler LA V8 engines with 318 A cylinder heads. This precision gasket features a 4.125-inch bore diameter and .045-inch compressed thickness, providing exceptional sealing capability for street and performance applications.

Key Features:

• Multi-Layer Steel (MLS) construction for superior durability and heat resistance
• 4.125-inch bore diameter optimized for Chrysler LA V8 applications
• .045-inch compressed thickness allows for precise compression ratio tuning
• Designed for use with 318 A cylinder heads
• Advanced embossment technology provides excellent sealing around combustion chambers and fluid passages
• Accommodates minor surface imperfections better than traditional composite gaskets
• Resistant to high combustion pressures and extreme temperatures

Cometic MLS gaskets are constructed with multiple layers of stainless steel, combining the benefits of a forgiving, malleable gasket with the strength and reliability required for high-performance engines. The unique MLS design allows the gasket to recover and maintain consistent clamping loads under extreme thermal cycling conditions. Ideal for street engines, mild performance builds, and applications requiring precise compression control on Chrysler 318 and compatible LA-series small block V8 engines.
