This setup is ideal for trucks that see a mix of daily driving, towing, and weekend work, especially after a mild tire size increase. The 4.56 ratio brings back low-end torque while keeping highway manners smooth and predictable. You will notice quicker throttle response, less gear hunting on grades, and a more confident feel when pulling a trailer. Yukon simplifies the process by bundling front and rear gears with their complete master overhaul kits, so you are not piecing parts together. Everything is designed to work as a system, which saves time and avoids headaches during installation. It is a smart upgrade that improves performance without changing the character of your truck.\u003c\/p\u003e\n\u003ch4\u003eDesigned For Dana 60 And 14 Bolt Drivetrains\u003c\/h4\u003e\n\u003cp\u003eThe Yukon YGK034 Re-Gear Package is engineered for 1999-2025 GM Silverado and Sierra 2500HD and 3500HD trucks equipped with a standard rotation Dana Spicer 60 front axle and a GM 10.5 inch 14-bolt rear axle. This package includes matching 4.56 ratio ring and pinion sets for both axles, along with Yukon master overhaul kits that provide bearings, shims, and seals for a complete rebuild. The thick gear design is intended for carriers originally set up for 4.10 and down ratios, ensuring proper gear engagement and strength. If your truck currently runs 3.54, 3.73, or 4.10 gears, a new front carrier will be required for installation. Yukon manufactures these gears using high-strength alloy steel, advanced heat treating, and precise machining to promote durability and quiet operation. The 4.56 ratio is well suited for moderate tire upgrades, towing, and heavy use without excessive RPMs at cruising speed. Professional installation is recommended to achieve proper setup and long-term reliability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e 1999, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025 GM Silverado\/Sierra 2500HD\/3500HD\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDesigned for 1999-2025 GM Silverado\/Sierra 2500HD and 3500HD trucks.\u003c\/li\u003e\n\u003cli\u003eFits standard rotation Dana 60 front and GM 10.5\" 14-bolt rear axles.\u003c\/li\u003e\n\u003cli\u003eIncludes front and rear 4.56 ratio ring and pinion gear sets.\u003c\/li\u003e\n\u003cli\u003eComes with complete Yukon Master Overhaul Kits for both axles.\u003c\/li\u003e\n\u003cli\u003eThick gear design works with 4.10 and down carriers.\u003c\/li\u003e\n\u003cli\u003eIf running 3.54, 3.73, or 4.10 ratios, a new front carrier is required.\u003c\/li\u003e\n\u003cli\u003eIdeal for trucks with mild to moderate tire size increases.\u003c\/li\u003e\n\u003cli\u003eRecommended for towing, hauling, and improved off-road performance.\u003c\/li\u003e\n\u003cli\u003eGears are manufactured with premium steel and advanced heat treatment.\u003c\/li\u003e\n\u003cli\u003eCovers both axles under one part number for easy ordering.\u003c\/li\u003e\n\u003cli\u003eBacked by Yukon's lifetime Y.E.S.
