Bring Back Strong Pull Without Sacrificing Driveability

If your truck feels sluggish after stepping up to bigger tires or heavier loads, the Yukon YGK037 4.88 Re-Gear Package is a solid way to wake it back up. This setup is aimed at drivers who want stronger low-end torque without pushing engine RPMs too high on the highway. The 4.88 ratio delivers a noticeable improvement in throttle response, especially when towing, hauling, or climbing long grades. Yukon makes the process easier by bundling front and rear gears with complete master overhaul kits, so you are not chasing extra parts mid-install. Everything works together as a matched system, which helps the truck feel smoother and more confident once it is back on the road. It is the kind of upgrade that makes your truck feel more capable every time you put it to work. For a balanced performance boost that fits real-world driving, this package hits the mark.

Engineered For Dana 60 And 14 Bolt Applications

The Yukon YGK037 Re-Gear Package is designed 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 kit includes matching 4.88 ratio ring and pinion sets for both axles, along with Yukon master overhaul kits that provide bearings, seals, and setup components. The thick gear design allows proper fitment with carrier setups intended for 4.10 and down ratios, ensuring strength and correct gear engagement. Yukon uses advanced machining and heat-treating processes to produce gears that run cooler, quieter, and last longer under load. The 4.88 ratio is well suited for trucks running larger tires that still see highway miles, offering a strong balance of torque and cruising comfort. All components are manufactured to meet strict quality standards for consistent performance. Professional installation is recommended to ensure proper setup and long-term reliability.
