It features a 3.42 ratio, making it a great match for trucks that require lower cruising RPMs without sacrificing towing capacity. With a 30-spline pinion shaft and a 12-bolt ring gear, this gear set is built to handle high torque loads while maintaining excellent durability under stress. Yukon uses advanced heat-treating techniques and precision machining to ensure each gear set runs smooth, quiet, and cool over the long haul.

The 11.50-inch ring gear diameter provides increased surface area and load distribution, which translates to improved gear life and consistent performance. For builders and techs looking for OE-level fitment with aftermarket strength, this gear set checks every box.
