Manufactured using a specialized gravity casting process, this piston utilizes an aluminum alloy with an 18% silicon content. This high-silicon composition is specifically chosen for two-stroke engines, offering distinct advantages over forged alternatives in lower cylinder pressure environments.\n\nBy incorporating high silicon levels, these pistons effectively decrease thermal expansion. This allows for tighter running tolerances, which improves engine power and performance while reducing the risk of premature wear or mechanical fatigue. The result is a piston that maintains its geometry at operating temperatures, ensuring consistent performance and a longer service life for your engine components.\n\n### Key Features\n\n \n- Precision Cast Aluminum: Gravity cast from high-quality aluminum alloy for structural integrity.\n \n- 18% Silicon Content: Engineered to minimize thermal expansion, allowing for tighter clearances.\n \n- Enhanced Durability: Superior wear characteristics significantly prolong the life of the piston skirt.\n \n- Optimized Performance: Designed to reduce rattling and engine noise while maintaining peak power output.\n \n- Twin Ring Design: Specifically configured for two-stroke efficiency.\n \n- Grade D: Precisely machined to 53.97mm specifications.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/husqvarna-tctesm-125-2014-2023-grade-d-5397mm-12-degree-twin-ring-vhm","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/a20102644ba0:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/a20102644ba0:1"}},"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.
