Product Details

Mr. Gasket 4805G Multi-Layer Stainless Steel (MLS) header gaskets are engineered specifically for GM LS-series engines from 1997 to 2015. These high-performance gaskets utilize a three-layer stainless steel construction that provides superior sealing and durability compared to traditional header gaskets.

Key Features:

  • Three-layer stainless steel construction for maximum durability and heat resistance
  • 0.072-inch thickness provides optimal sealing without excessive compression
  • Round port design with 1.75-inch diameter to match LS-series exhaust ports
  • Designed to withstand the scrubbing action caused by different expansion rates between aluminum cylinder heads and steel headers
  • Will not deteriorate or blow out under extreme heat and pressure cycling
  • Direct fit for GM LS1, LS2, LS3, LS6, LS7, and other LS-series engines

The multi-layer stainless steel design allows these gaskets to flex and conform to slight irregularities in the mating surfaces while maintaining a reliable seal. This construction method is far superior to conventional composite or embossed metal gaskets, especially in high-performance applications where exhaust temperatures and pressures are elevated. The stainless steel material resists corrosion and maintains its integrity through countless heat cycles, making these gaskets an excellent choice for street performance, track, and racing applications.
