SpeedFactory Racing High Compression Pistons

Unlock the full potential of your Honda® B-series build with SpeedFactory's mid/high compression cast pistons, engineered to deliver reliable, all-motor performance gains without sacrificing durability. The pistons are manufactured from high-strength AC9B hypereutectic aluminum alloy, offering exceptional heat resistance, reduced scuffing, and improved wear compared to OEM components, while precision CNC-machined crowns and an enlarged top land enhance strength under demanding conditions. Featuring a low-friction moly skirt coating for smoother operation and tighter piston-to-wall clearances, they promote superior ring seal, increased efficiency, and more usable power across the rev range. Designed to work with both factory and aftermarket rods, these pistons are available in multiple bore sizes with different compression ratios. They are the ideal upgrade for builders looking to maximize horsepower, throttle response, and long-term reliability in naturally aspirated B-series engines. Order pistons for your application.
