Product Details

The Cometic C5457-066 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chrysler LA V8 engines. This precision-engineered gasket features a 4.125-inch bore diameter and a compressed thickness of .066 inches, providing an optimal seal between the cylinder head and engine block.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • .066-inch compressed gasket thickness for precise compression ratio control
  • 4.125-inch bore diameter designed for Chrysler LA V8 applications
  • Engineered to withstand extreme cylinder pressures and temperatures
  • Allows for thermal expansion and contraction without compromising the seal
  • Ideal for performance builds, forced induction, and high-compression applications

Cometic's MLS gaskets feature multiple layers of stainless steel with elastomeric coatings that micro-seal surface imperfections, making them an excellent choice for both street and racing applications. This gasket is compatible with Chrysler LA V8 engines including 318, 340, and 360 cubic inch displacements when bored to the specified 4.125-inch diameter.

purchased two shocks for my truck, best price online , they were here within a week. I will definitely order from them again....thanks....

Excellent communication, quick, easy, and lowest price.

quick delivery of the parts I need to fix my jeep

Web site is very easy to follow or use. I'm thinking of finding other parts here. The battery has been delivered so quickly. It'd be better to see the order status changed from processing to shipping (or something) to know that it actually was shipped. Bu

Quick shipping. Good info on sttud will definitely irder again
