Built For Dana 60 And 14 Bolt Applications

The Yukon YGK040 Gear Package is engineered for 1999-2025 GM Silverado and Sierra 2500HD and 3500HD trucks equipped with a standard rotation Dana 60 front axle and a GM 10.5" 14-bolt rear. This complete kit includes 5.38 ratio front and rear ring and pinion gear sets, as well as Yukon’s premium master overhaul kits for a thorough and reliable install. The thick gear design is specifically intended for use with 4.10 and down carriers, ensuring proper gear mesh and strength under load. If your truck currently runs 3.54, 3.73, or 4.10 gears, you’ll need to upgrade the front carrier to complete the installation. Yukon uses precision machining, advanced heat-treating, and rigorous quality control to ensure every gear set meets exact specifications for quiet, long-lasting performance. This kit is ideal for those running oversized tires, towing heavy loads, or demanding more from their drivetrain in off-road conditions. With all parts designed to work together, it simplifies the re-gear process and delivers dependable results.
