The \"R\" designates reverse rotation - a critical distinction for the Ford Dana 60 high pinion front axle; standard rotation gears are not compatible. The \"T\" designates Thick - a thicker ring gear tooth profile that allows the 4.30 ratio to be used with the factory 4.10 \u0026amp; down (3-series) carrier case, bypassing the need to purchase a 4.56 \u0026amp; up high carrier case.\u003c\/p\u003e\u003cp\u003e The 4.30 ratio is a popular first-step regear for Super Duty owners running 35\"-37\" tires who want to restore stock-like throttle response, towing performance, and drivability without going to the expense of a carrier swap. Yukon manufactures these gear sets from high-grade alloy steel with advanced heat-treating and precision CNC finishing, engineered to run quietly and last under the high-torque demands of diesel and gas-powered Super Duty trucks. Confirm that your carrier is the 4.10 \u0026amp; down series before ordering, and match this front gear to a compatible rear gear set for correct 4WD operation. A master install kit is required and sold separately.\u003c\/p\u003e","brand":"Yukon Gear \u0026 Axle","offers":[{"title":"Default Title","offer_id":55116559286591,"sku":"YUKYG D60R-430R-T","price":309.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/7308\/9343\/files\/33352c1e739dd44900a0bf2c7bf3551dL_23176dce-c433-4325-a655-cf0ac6755a8d.jpg?v=1786902325","url":"https:\/\/wcaperformance.com\/products\/yukon-gear-high-performance-gear-set-for-dana-60-reverse-rotation-in-a-4-30-ratio-thick","provider":"WCA Performance","version":"1.0","type":"link"}
