Product Details

The Cometic C5454-080 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chrysler Gen-2 Hemi engines. This high-performance gasket features a 4.280-inch bore diameter and a compressed thickness of .080 inches, making it ideal for both stock rebuilds and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability
  • 4.280-inch bore diameter optimized for Gen-2 Hemi engines (5.7L, 6.1L, 6.4L)
  • .080-inch compressed thickness for proper compression ratio
  • Advanced coating technology ensures excellent conformability to head and block surfaces
  • Engineered to handle extreme cylinder pressures in high-performance and forced induction applications
  • Reusable design allows for removal and reinstallation during engine assembly

Cometic's MLS gaskets use multiple layers of stainless steel with specialized coatings to create a reliable seal that withstands the thermal expansion and contraction cycles of modern engines. The .080-inch thickness provides the proper quench height and compression ratio for modified or performance Gen-2 Hemi builds. This gasket is compatible with aftermarket cylinder heads and blocks that maintain the 4.280-inch bore specification.

great prices great service will make a purchase again

Fast shipping, great product. Nothing more needs to be said.

Shipping was fast and without damage and the price was great.

I ordered a Jet Powr-Flo, SKU: JET-69190, from Autoplicity and it was at least 40% off the regular JET price. The site was off on all the vehicles the component fits, but I knew what part to get and I'm completely satisfied. My 2008 Mustang is running smoother than ever and wasting less fuel. So for any performance parts I'll search the maker sites first but I'll purchase from Autoplicity first.

the shipping charges were high, but still cheaper than any place else with free shipping!
