{"product_id":"3-73-ring-and-pinion-gear-kit","title":"3.73 Ring and Pinion Gear Kit","description":"The Richmond 3.73 Ring and Pinion Gear Kit offers enhanced acceleration for your 1999-2004 Ford Mustang GT, allowing you to leave the line faster and reach your power band more quickly.\n\nManufactured in the United States, Richmond Gear ensures high standards in machining, finishing, and heat treating. This ensures gears with acceptable tolerances, durability, and fit. The kit includes a 3.73 gear ratio and an 8.8\" ring gear diameter. It is backed by a 2-year or 100,000-mile warranty.\n\nWhen changing your differential's gear ratio, your speedometer calibration will become inaccurate. A Tuner or Recalibration Tool (sold separately) is required to correct this. An Installation and Bearing Kit is highly recommended, especially for high-mileage Mustangs. Additionally, a 28-spline S-Spring (sold separately) is necessary for 28-spline Mustangs if you opt for a Trac-Lok rebuild during installation.","brand":"Richmond","offers":[{"title":"Default Title","offer_id":52663493689656,"sku":"66501G99","price":443.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687136179.webp?v=1784327482","url":"https:\/\/store.motormia.co\/products\/3-73-ring-and-pinion-gear-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
