Product Details

The Cometic C5457-045 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chrysler LA small-block V8 engines. This gasket features a compressed thickness of .045 inches and is designed for engines with a 4.125-inch cylinder bore diameter.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme conditions
  • .045-inch compressed gasket thickness for precise compression ratio tuning
  • 4.125-inch bore diameter accommodates stock and modified Chrysler LA V8 applications
  • Advanced MLS design withstands high cylinder pressures and temperatures
  • Eliminates gasket failure common with composite head gaskets in performance applications
  • Requires proper surface preparation with RA finish of 50-60 for optimal sealing

Cometic MLS gaskets are the preferred choice for performance and racing applications where reliability and precision are critical. The multi-layer steel construction allows the gasket to recover and maintain sealing integrity through repeated heat cycles, making it ideal for turbocharged, supercharged, and high-compression naturally aspirated builds.

Part was only available at Autoplicity, shipping was super quick will do business with them again.

I was happy to find Autoplicitys website in Google Checkout, as they really had the best price on the web. They quickly shipped to me a WeatherTech 2007 - 2011 Acura RDX Cargo Liner in black, just like I ordered. I will order from them again in the future.

Great price and fast shipping

Lowest prices, great service. Thanks.
