Engineered for precision and reliability, this piston is the ideal choice for riders looking to restore factory-level performance to their machine.\n\nVertex two-stroke pistons are gravity cast from a high-quality aluminum alloy featuring an 18% silicon content. This specific material composition is designed to meet the unique demands of two-stroke engines, which typically operate with different cylinder pressures than four-stroke counterparts.\n\n### Key Features\n\n \n- Advanced Silicon Composition: The 18% silicon content significantly decreases thermal expansion. This allows the piston to maintain its geometry at operating temperatures, enabling tighter tolerances for improved power and performance.\n \n- Reduced Wear: The specialized alloy offers superior wear characteristics, effectively prolonging the lifespan of the piston and reducing degradation of the piston skirt.\n \n- Quiet Operation: Due to lower thermal expansion, these pistons are less susceptible to rattling or breaking, ensuring smoother engine operation.\n \n- Twin Ring Design: Engineered to provide an optimal seal within the cylinder, maximizing compression and efficiency.\n \n- High-Quality Construction: Gravity cast for consistent density and durability, meeting the high standards expected for engine internals.\n\nWhether you are performing a routine top-end rebuild or addressing engine wear, the Vertex Grade A twin ring piston provides the durability and performance characteristics required to keep your engine running at its peak.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/husqvarna-wr-300-2008-2013-grade-a-7194mm-twin-ring-piston","buyOneNow":null,"basketWithThis":null}},"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.
