Supertech Forged Pistons

Engineered for Precision. Built for Power.

Supertech forged pistons are the result of over 40 years of engineering excellence and advanced manufacturing. Designed using the latest CAD and Finite Element Analysis (FEA) software, every piston is optimized for strength, balance, and reliability in both naturally aspirated and high-boost turbocharged engines.

Premium Materials & Advanced Forging

Each Supertech piston is forged from either high-silicone 4032 aluminum alloy or high-strength 2618 aluminum alloy, depending on the application. The 4032 alloy provides exceptional wear resistance and thermal stability for street and endurance builds, while the 2618 alloy offers superior ductility and fatigue resistance for extreme racing and high-boost conditions.

Supertech uses a multi-stage forging process that aligns material grain with stress paths, maximizing tensile strength and durability. Each piston undergoes precision CNC machining to ensure perfect dimensional accuracy and balance.

Surface Treatments & Coatings

• Phosphate Dry Lubricant Coating – Protects ring grooves and skirts from micro-welding and reduces friction.
• Contact Reduction Grooves – Enhance lubrication between the piston and cylinder wall.
• Diamond-Tool Machining – Ensures ultra-flat ring grooves and consistent sealing.

Performance Benefits

• Excellent wear resistance and thermal conductivity for long service life.
• Superior strength under high boost and race-level conditions.
• Reduced piston-to-wall clearance for quieter operation and tighter sealing.
• Optimized skirt profiles for lower friction and smoother operation.
• Available for naturally aspirated, turbocharged, and nitrous-assisted engines.

Race-Proven Reliability

Supertech forged pistons are trusted by professional engine builders worldwide for their dimensional precision, heat management, and uncompromising strength. Each set includes high-strength chrome-moly wrist pins and premium Japanese-manufactured piston rings for complete performance assurance.

Popular Applications

Supertech forged pistons are available for leading performance platforms including Honda B16, Toyota B58, Nissan KA24, Subaru FA20, BMW S54, Volkswagen 1.8T, Audi AEB, Ford Ecoboost, and Mitsubishi 4G63.

Whether you’re building a reliable street motor or a record-setting race engine, Supertech pistons deliver the strength, precision, and performance you need to push limits with confidence.
