Product Details

The Cometic C5454-056 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chrysler Gen-2 Hemi engines. This gasket features a 4.280-inch bore diameter and a compressed thickness of .056 inches, making it ideal for stock and mildly modified applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior sealing and durability
  • 4.280-inch bore diameter optimized for Gen-2 Hemi combustion chambers
  • .056-inch compressed thickness for proper compression ratio
  • Advanced coating technology prevents fretting and corrosion
  • Maintains seal integrity under extreme cylinder pressures and temperatures
  • Engineered for proper torque retention and reusability

Cometic MLS head gaskets utilize multiple layers of stainless steel with elastomeric coatings to create a gasket that recovers from thermal expansion and contraction cycles. The embossed layers provide multiple sealing points around combustion chambers, oil passages, and coolant ports. This design is particularly effective in high-performance applications where traditional composite gaskets may fail.

Application: Chrysler Gen-2 Hemi engines including 5.7L and 6.1L variants (verify fitment for your specific application).

GREAT PRICES AND COMMUNICATION!!!! HIGHLY RECOMMENDED STAFF AND PRODUCTS!!!!!

Finding the part, and ordering it was great. But UPS dropped the otherwise phenomenal ball... Ordered the item on Wednesday... got it the next MONDAY. I ordered it Second Day Air. Then I find out, "Oh, it's Second BUSINESS Day Air... we don't work

It was great

My Superchips Cortex arrived within a few days of order and by far was the best price arround. Product arrived in perfect condition and worked as described. Great deal. Order #10984

Thanks again! Best prices I found on the web! Fast shipping Would definitely buy from again!

In a rush to get my car up and running, Autoplicity had the best price on the items I needed, and in stock as well as shipped quickly. Just what I was looking for, thanks!

Great price. Minor problems with shipping because of UPS (dropped box and broke part, late delivery). Autoplicity sending me out replacement part.
