Product Details

The Cometic C5749-066 is a precision-engineered Multi-Layer Steel (MLS) cylinder head gasket designed specifically for Chrysler 5.7L Gen-3 Hemi engines. This high-performance gasket features a 4.100-inch bore diameter and .066-inch compressed thickness, making it ideal for both stock rebuilds and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme conditions
  • 4.100-inch bore diameter accommodates stock and mildly overbored cylinders
  • .066-inch compressed thickness for precise compression ratio tuning
  • Engineered for Chrysler 5.7L Gen-3 Hemi engines (2003-2008)
  • Compatible with right-hand side (RHS) cylinder head applications
  • Exceptional resistance to combustion pressure and thermal cycling
  • Eliminates the need for additional sealants or re-torquing

Cometic MLS gaskets utilize multiple layers of stainless steel with precision-formed embossments that provide superior sealing around combustion chambers, coolant passages, and oil galleries. The advanced material construction allows the gasket to recover and maintain clamping load even under extreme thermal expansion and contraction cycles, making it an excellent choice for high-performance street and racing applications.

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.

Amazing prices and amazing shipping speed! Best all around. Will be ordering more soon!
