Cometic .040" MLS Head Gasket – Dodge 6.1L HEMI (Right or Left – Sold Individually)

The Cometic C5876-040 .040" MLS Head Gasket is a premium high-performance sealing solution for the Dodge 6.1L HEMI V8 engine. Constructed from multiple embossed layers of stainless steel with Viton rubber coating on the outer layers, this multi-layer steel (MLS) gasket delivers exceptional sealing under extreme heat, pressure, and thermal cycling. The .040" increased thickness compensates for warped or milled surfaces, ensuring a perfect compression seal and leak-free performance on stock, high-performance, supercharged, or turbocharged 6.1L SRT8 HEMI builds.

Key Features

  • Multi-Layer Steel (MLS) Construction – Multiple embossed stainless steel layers for superior rebound and sealing
  • .040" Increased Thickness – Compensates for surface imperfections and warped heads
  • Viton Rubber Coating – Heat-resistant to 482°F (250°C) and designed for harsh sealing environments
  • Precision Fitment – Exact match for the 4.100" bore 6.1L HEMI cylinder head
  • No Sealants Required – MLS design provides reliable sealing without additional sealants
