    Supertech High Performance Head Gaskets

    Engineered to Seal. Built to Win.

    Supertech head gaskets deliver superior sealing for boosted, high-compression, and competition engines. Each gasket is laser-cut from premium stainless steel for exact fitment and stress-relieved to endure extreme temperature and pressure cycles. Our MLS design features gas-stopper embossments and a uniform polymer coating to maintain a leak-free seal—even on less-than-perfect surfaces.

    Precision Meets Performance

    • Laser-Cut Stainless Construction for dimensional accuracy and consistent sealing.
    • Stress-Relieved Embossments to prevent cracking under high boost.
    • Advanced Polymer Coatings to micro-seal surface imperfections and resist heat cycling.
    • Application-Specific Fitment for OEM and race-built engines.
    • Race-Proven Reliability tested in extreme motorsport and dyno environments.

    Fire Ring Options for Extreme Builds

    Select applications feature Fire Ring gaskets—steel-core composites with separate stainless cut-rings for unmatched cylinder pressure sealing in ultra-high horsepower setups. A silicone-based sealing bead is applied around critical oil and coolant passages for maximum reliability.

    Compatible Applications

    Direct-fit coverage for top platforms, including Honda B-Series, Toyota 2JZ, Subaru EJ20, BMW S54/S52, Nissan SR20, and VW/Audi EA888.
