Replacement head gasket engineered for long-term reliability. 🔧

Built to handle high-performance and modified engines, this gasket resists creep, cracking and brittle failure while maintaining a dependable combustion seal.

  • High-quality products for long-term reliability.
  • Manufactured from premium fuel-resistant materials that will not creep, crack or become brittle.
  • MLX gasket features an extra “stopper” fold-over layer providing a torque-limiting surface that prevents yielding of the combustion seal.
  • Essential for turbo, high-compression, nitrous or any power-adding modifications.
  • Proprietary high-temperature coatings and embossments provide a micro seal for fluids against the head and block surface.
  • Multi-layer design with Viton®-coated embossed spring steel outer layers and an inner steel layer for added support.
  • Made in the USA. 🇺🇸

Install and torque to manufacturer specifications. If you are unsure about fitment, consult a professional mechanic. 🔩
