Product Details

The Cometic C5753-030 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Buick Big Block V8 engines. This precision gasket features a 4.312-inch bore diameter and .030-inch compressed thickness, designed to provide superior sealing performance in demanding applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for maximum durability and heat resistance
  • 4.312-inch bore diameter optimized for Buick Big Block V8 engines
  • .030-inch compressed thickness for precise compression control
  • Advanced sealing technology prevents combustion gas leakage and coolant seepage
  • Ideal for performance builds, forced induction, and high-compression applications
  • Accommodates minor surface imperfections for reliable sealing

Cometic's MLS gaskets utilize multiple layers of stainless steel with specialized coatings to provide exceptional conformability and recovery characteristics. The embossed layers create superior sealing stress while maintaining the ability to rebound under extreme cylinder pressure and temperature cycling, making this gasket an excellent choice for street performance and racing applications.

Cool site.

I am extremely satisfied with Autoplicity in terms of service, price, and shipping. I was shopping for a set of N-FAB step bars for my truck and was ready to purchase from Amazon when I decided to look around to see if there were better prices. I stumbled upon Autoplicity and was surprised to see their price on the bars. I checked with their online chat customer service to confirm that they would fit my truck and that the price was for a pair of the bars and not just one. (That's how low the price was!). I then placed my order and the bars arrived at my doorstep 3 days later! Autoplicity gets an A+ in my book and I'll definitely be coming back.

Fantastic ! Ordered a Weather Tech Cargo Liner for my 2012 Ford Explorer. Price was $60 less here than ALL other sites on web. I was skeptical that this was going to be a counterfeit -- as the price was too good to be true. I was extremely happy to receive the genuine product as I expected in less than a week -- and for $60 less than the competitors ! GREAT VALUE and great service ! I will definitely be back !!

Very fast shipping and price is rite
