By utilizing premium steel construction and advanced engineering, this sprocket offers a robust solution for off-road and race machinery.\n\n### Advanced Tri-Zinc Coating Technology\n\nTo ensure peak performance and environmental resistance, this sprocket undergoes a specialized Tri-Zinc plating process. This triple-layer finish provides superior protection and maintenance benefits:\n\n \n- Corrosion Resistance: An initial layer of silver and nickel actively fights against rust and oxidation.\n \n- Passivation Layer: A black passivation step seals micro-pores on the steel surface, preventing abrasive debris and road grit from lodging in the sprocket teeth.\n \n- Protective Top Coat: The final slick, smooth finish keeps the component clean and maintains a professional aesthetic throughout its service life.\n\n### Key Features\n\n \n- Rugged Construction: CAD designed and precision laser cut for an exact fit and superior structural integrity.\n \n- Optimized Tooth Profile: Designed with extra-thick teeth to improve drive chain engagement and significantly extend the lifespan of the sprocket.\n \n- Reduced Rotating Mass: Features a lightened core design that reduces rotating weight by up to 20 percent compared to standard steel sprockets, improving acceleration and handling.\n \n- Stock Compatibility: Engineered to retain the stock pitch, ensuring a straightforward replacement process.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/husqvarna-crwrtcte-125250300310450-1990-2013-steel-rear-sprocket-51-tooth","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.
