Product Details

The Cometic C5489-080 is a premium multi-layer steel (MLS) cylinder head gasket engineered specifically for GM LS-series Gen III and Gen IV small block V8 engines, including LS1, LS2, LS3, and LS6 applications. This high-performance gasket features a 4.100-inch bore diameter and .080-inch compressed thickness, making it ideal for stock rebuilds and performance applications.

Key Features:

  • Multi-layer steel construction provides superior sealing and durability under extreme cylinder pressures
  • 4.100" bore diameter accommodates standard and mild overbore LS engines
  • .080" compressed thickness (80 thousandths) for precise compression ratio tuning
  • Compatible with LS1, LS2, LS3, LS6, and other Gen III/Gen IV LS engines
  • Embossed stainless steel armor around combustion chamber and fluid passages
  • Viton rubber sealing beads for exceptional oil and coolant sealing
  • Designed to withstand high-performance and forced induction applications

Cometic MLS gaskets are the preferred choice for engine builders and performance enthusiasts who demand reliable sealing in demanding applications. The multiple layer design allows the gasket to conform to minor surface imperfections while maintaining consistent clamping force across the entire sealing surface.

A week ago I ordered a H3RHG100C 1.4 lb Halotron fire extinguisher. I mentioned "a week ago" because that is how long it took from order to delivery across the U.S.!! Now that I look at the paperwork, it wasn't even a full week. Autoplicity is now my #1 parts supplier for my 2010 Camaro. They could not have been any better overall. Ordering, checkout, stock and shipping. All above and beyond my expectations Great site, great communication. A1 people.
