Product Details

The Cometic C5457-120 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Chrysler LA small block V8 engines. This precision gasket features a 4.125-inch bore diameter and a compressed thickness of .120 inches (120 thousandths), making it ideal for performance builds and applications requiring enhanced sealing capabilities.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under high cylinder pressures
  • 4.125" bore diameter accommodates stock and mildly overbored Chrysler LA V8 engines
  • .120" compressed thickness allows for precise compression ratio tuning
  • Engineered for high-performance applications including forced induction and nitrous oxide systems
  • Resists combustion gas leakage, coolant seepage, and oil migration better than traditional composite gaskets
  • Compatible with aluminum and cast iron cylinder heads

Cometic's MLS gaskets feature multiple layers of stainless steel with elastomeric coatings that conform to sealing surfaces while maintaining structural integrity under extreme temperatures and pressures. This gasket is designed for Chrysler LA V8 engines including 273, 318, 340, and 360 cubic inch variants. Proper surface preparation with RA finish specifications and correct torque procedures are essential for optimal performance.

first time ive order from here and my experience was great! shipping was crazy fast. and they had the best price shipped on the 2jz arp head stud set i could find. also how on their site they actually list if they have the part in stock and how many which is very helpful. ive payed for parts to find out the vender didn't even have them available. which lead to more down time. and we all hate down time :)

Best price on the internet. A lot cheaper than amazon, so I was pretty surprised.

This is the first time I've ordered from Autoplicity. I found they had the best price on the item I was looking for and decided to try them. I ordered this item yesterday(Sunday) and was just informed that it shipped. That is quick. I am pleased with their customer service and will use them as my first source.

Ordered a CTEK charger. Great price, and recieved it in 3 days. Very pleased.

Excellent customer service. Treated me very well. Issued a refund, no problem. Thank you!!

I purchased a wind reducer for my cross bars, autoplicity had the best price availalbe, my order shipped timely and I received communications throughout the process. I will use this site again.
