Engineered for superior strength and optimal combustion, this kit is designed to enhance your engine's efficiency and power output. Wossner pistons are known for their exceptional design and durability, ensuring reliable performance for demanding riders.\n\n#### Key Features:\n\n\t\n- Advanced Forged Design: Wossner forged pistons offer superior strength and advanced design compared to standard pistons.\n\t\n- Optimized Heat Transfer: Engineered to efficiently transfer combustion chamber heat to the cylinder walls, promoting better engine cooling and performance.\n\t\n- Elliptical Piston Shape: The elliptical design ensures a more uniform bearing surface as the piston heats and expands. This eliminates localized pressure points, distributes thrust loads evenly, and prevents piston collapse under high stress.\n\t\n- Premium Material: Made in Germany, ensuring high manufacturing standards and top-tier quality.\n\t\n- Precision Bore: Features a precise bore size of 91.50mm for a perfect fit and optimal compression.\n\t\n- Specific Components: Includes Lock Part Number CW20, Pin Part Number WP038, and Ring Set Part Number 915XSY for a complete and integrated solution.\n\n#### Technical Specifications:\n\n\t\n- Wossner Part Number: 8550DB\n\t\n- Bore: 91.50mm\n\t\n- Displacement: 399 cm3\n\t\n- Stroke: 60.80 mm\n\t\n- Clearance: 0.06 mm\n\t\n- Compression Height: 24.50 mm\n\t\n- Dome Volume: +1.90 cm3\n\t\n- Compression Ratio: OEM\n\t\n- OEM Compression Ratio: 11.40:1","weightGrams":null,"fitments":[{"make":"HUSQVARNA","model":"SMR 400","cc":null,"notes":null,"years":"2001–2007"},{"make":"HUSQVARNA","model":"TC 400","cc":null,"notes":null,"years":"1999–2001"},{"make":"HUSQVARNA","model":"TE 400","cc":null,"notes":null,"years":"2001–2003"}],"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-tc400-99-01-9150mm-wossner-8550db-husqvarna","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/baab04db0f59:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/baab04db0f59:1"}},"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.
