  • EST kits ensure critical seal and superior durability that meets and exceed OE specifications
  • MLS (multi-layer-steel) head gaskets are ideal for any combination of head and cylinder materials, comprised of two embossed viton coated stainless steel outer layers and variable stainless center layer
  • The variable center layer allows us to create multiple gasket thickness options, no re-torque is required after initial torque set
  • Rubber coated single layer steel base gaskets are viton rubber coated with a steel core
  • AFM material engine cover gaskets are made for a chemically blown compounded nitrile synthetic rubber that is bonded to an aluminum core.
  • AFM has a temperature resistance of over 250 degrees F and an 85 percent recovery while maintaining a strong torque retention, they also install dry and do not require a re-torque
  • Viton valve stem seals are made from hi-temperature Flouroviton with Teflon to prolong valve stem life and have a spring on the wiper to maintain a positive seal
  • Race style exhaust gasket that will not fray into the port
  • Copper washers and Viton o-rings are used to seal drain plugs and engine covers with stock o-ring seals
