Engineered in the USA and manufactured in Taiwan, it utilizes hypereutectic cast aluminum with a high silicon content. This advanced material offers reduced heat expansion, tighter clearances, increased hardness, and improved resistance to scuffing for a longer lifespan.\n\nThe piston features a precisely machined, smooth crown to minimize carbon buildup, contributing to increased horsepower and better fuel economy. For even greater durability, the crown is hard anodized, making it 75% stronger than non-anodized versions. This reduces minimal expansion and significantly lowers the risk of cold seizures.\n\nThe piston skirts are treated with a MOS2 (Teflon/Molybdenum) coating. This advanced coating performs to the highest standards, reducing friction and heat build-up to deliver added power and extended engine life. Namura rings are designed to match the Original Equipment Manufacturer (OEM) specifications.\n\n#### Key Features:\n\n \n- Oversize: 1.00mm\n \n- Bore: 91.00mm\n \n- Material: High-silicon content Hypereutectic cast aluminum\n \n- Machined smooth piston crowns for reduced carbon buildup, increased horsepower, and fuel economy\n \n- Hard anodized crowns for 75% increased strength and minimal expansion\n \n- Teflon/Molybdenum (MOS2) coated skirts to reduce friction and heat\n \n- Namura rings designed to match OEM specifications","weightGrams":null,"fitments":[],"collections":[{"name":"Engine","url":"https://www.2brosparts.com/api/agent/collection/GB/engine"},{"name":"Pistons & Kits","url":"https://www.2brosparts.com/api/agent/collection/GB/pistons-kits"}],"links":{"page":"https://www.2brosparts.com/products/piston-kit-ltz400-kfx400-9100-namura-na-30002-4-suz-kaw","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/ff936fdaf20a:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/ff936fdaf20a:1"}},"market":{"country":"GB","countryName":"United Kingdom","locale":"en-gb","currency":"GBP","exchangeRateFromGbp":1,"pricesIncludeUkVat":true,"checkoutTax":null,"delivery":[{"name":"Standard","description":"Orders £15.00–£59.99 · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":4.99,"formatted":"£4.99"},"free":false,"minimumOrder":{"amount":0,"formatted":"£0.00","gbp":0},"weightGrams":null},{"name":"Standard","description":"Orders £60.00 and up · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":0,"formatted":"£0.00"},"free":true,"minimumOrder":{"amount":60,"formatted":"£60.00","gbp":60},"weightGrams":null}],"storeUrl":"https://www.2brosparts.com"},"navigate":{"start":"https://www.2brosparts.com/api/agent","search":"https://www.2brosparts.com/api/agent/search/GB/{words+joined+with+plus}"},"howToBuy":{"summary":"Build a basket for the shopper and give them one checkout link.
