Left-hand cylinder head gasket for the GM 6.6L Duramax turbo diesel. Fel-Pro built this PermaTorque MLS gasket to replace all five OE head gasket versions on one part number: it covers every model year along with OE grades A, B and C, and works on over-bored blocks.
Key Features
- PermaTorque MLS construction using multiple layers of stainless steel to maintain sealing stress and accommodate head lift
- LaserWeld stopper layer helps build a stronger combustion seal and resists blow-out damage
- Proprietary coating seals surface finishes as rough as 80 Ra
- Embossed sealing beads at all vital areas to close off leak paths
- Designed to resist over-compression of the embossments under peak combustion pressure and temperature
