This standard size B cast replica piston kit is designed to meet or exceed OEM specifications, ensuring optimal fit and function for a wide range of applications.\u003c\/p\u003e\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Prox Cast Piston Kit is a premium choice for riders seeking dependable engine rebuilds or performance enhancements for their 2-stroke powerplants. Utilizing advanced gravity casting techniques, each \u003cstrong\u003eProx aluminum alloy piston\u003c\/strong\u003e is crafted with approximately 18 percent silicon content. This crucial silicon integration significantly enhances the piston's stability and remarkably decreases thermal expansion, leading to more consistent performance and extended engine life under varying operating temperatures.\u003c\/p\u003e\n\u003cp\u003eWhile Prox piston designs often mirror OEM configurations, their expert engineers meticulously evaluate every opportunity to introduce subtle adjustments that can yield increased performance. This commitment to innovation means you get a component that's not just a replacement, but often an upgrade. The durability of these pistons makes them a very stable and reliable core for your engine. Furthermore, Prox 2-stroke pistons are versatile, manufactured to be compatible with both traditional cast iron cylinder bores and modern Nikasil cylinder bores, offering broad application flexibility. For Nikasil bores, Prox provides a comprehensive range of oversizes, graded in A\/B\/C\/D sizing, with each increment going up by 0.01mm in diameter to ensure a precise, tailored fit for your specific rebuild needs.\u003c\/p\u003e\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEnhanced OEM-Style Design:\u003c\/strong\u003e Engineered to closely match OEM specifications, with strategic performance adjustments by Prox engineers for improved power and efficiency.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSuperior Stability \u0026amp; Durability:\u003c\/strong\u003e Manufactured through gravity casting using a high-grade aluminum alloy with approximately 18% silicon content, ensuring exceptional stability and long-lasting performance.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOptimized Thermal Management:\u003c\/strong\u003e The significant silicon content actively reduces thermal expansion, maintaining piston integrity and consistent clearances across diverse operating conditions.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBroad Cylinder Compatibility:\u003c\/strong\u003e Specifically designed for seamless integration with both traditional cast iron cylinder bores and advanced Nikasil-plated cylinder bores.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePrecision Oversizing Options:\u003c\/strong\u003e For Nikasil cylinders, Prox offers a detailed range of A\/B\/C\/D oversizes, with each step increasing the diameter by 0.01mm for a perfect, custom fit during engine rebuilds.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eStyle:\u003c\/strong\u003e Cast Replica\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEngine Type:\u003c\/strong\u003e 2-Stroke\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePiston Material:\u003c\/strong\u003e Aluminum Alloy, Cast\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePiston Diameter:\u003c\/strong\u003e 53.96 mm\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePiston Size:\u003c\/strong\u003e Standard Size B\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRing Material:\u003c\/strong\u003e Steel\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eUnits:\u003c\/strong\u003e Kit\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVendor Part Number:\u003c\/strong\u003e 01.7228.B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Prox","offers":[{"title":"Default Title","offer_id":62381527400778,"sku":"09106176","price":162.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/3f707d9a49bbcf6d37ae12e5377837ed.webp?v=1781741339","url":"https:\/\/partsdenmark.com\/products\/prox-cast-piston-kit-for-2-stroke-engines","provider":"Parts Denmark","version":"1.0","type":"link"}
