Supertech – premium engine components for Honda performance builds

Supertech is a U.S.-based manufacturer that specializes in high-performance engine components. Founded in California in the 1990s, the brand quickly earned recognition in the motorsport world – from drag racing to professional track series. Today, Supertech parts are trusted both by tuning workshops and by enthusiasts rebuilding their Honda engines with premium-grade components.

History and brand philosophy

From the beginning, Supertech has focused on precision and durability. All components are designed in the United States and produced using advanced metal alloys under strict motorsport-level quality control. The company’s mission is to create products capable of withstanding higher RPM, pressure, and temperature than OEM parts. As a result, Supertech has become synonymous with reliability and performance among Honda tuners and race builders worldwide.

Supertech product range

Although JDMshop currently offers mainly Supertech valve stem seals, the brand’s full catalog includes a wide range of precision-engineered components such as:

• intake and exhaust valves made of stainless steel, titanium, or Inconel,
• valve springs and complete spring & retainer kits,
• valve guides and seats,
• pistons, cylinder hardware, and camshaft components,
• and many other high-performance engine accessories.

Thanks to JDMshop’s cooperation with the official distributor, any Supertech product can be ordered on demand — even if it’s not currently listed in the store.

Supertech valve stem seals – precision and endurance

The most popular Supertech items among Honda owners are valve stem seals. These small yet crucial components are known for excellent fitment, oil resistance, and long-term reliability. Supertech uses specialized materials such as Viton for the exhaust side and high-elastic compounds for the intake side, ensuring reliable sealing even under extreme heat and high RPM.

Supertech valve stem seals are available for engines like Honda B16, B18, K20, K24, D16, H22 and other JDM powerplants. They are strongly recommended for head rebuilds, valve train upgrades, or turbo setups. Even on stock engines they deliver better sealing, reduced oil consumption, and longer life.

Why choose Supertech for your Honda?

Supertech components are engineered for strength and precision. In practice this means a wider safety margin at high RPM, better valve control, and greater reliability. Workshop feedback and user reviews consistently praise Supertech for:

• perfect fitment in Honda cylinder heads,
• dimensional stability at extreme temperatures,
• durability in high-rev or turbocharged engines,
• and an excellent quality-to-price ratio in the premium segment.

If you are rebuilding or tuning your Honda engine for more power, Supertech is a smart investment — a proven choice trusted by professional engine builders around the world.
