Yukon Gear 30 Spline 4340 Chrome-Moly Axle & Grizzly Locker Kit For Jeep TJ / XJ / YJ & Zj

If you're looking to significantly upgrade the front axle strength and traction for your 1987-2006 Jeep Wrangler, Cherokee (XJ), Grand Cherokee (ZJ), or YJ, this Yukon Gear & Axle Chromoly Front Axle & Grizzly Locker Kit is a solid choice. This kit is designed for the Dana 30 front differential and includes everything you need to replace your stock axles and add a selectable locker for serious off-road capability.

The heart of this kit is the Yukon Grizzly Locker, which provides automatic traction when you need it most, especially in low-traction situations. It's paired with heavy-duty 4340 chrome-moly inner and outer axles, known for their high tensile strength and resistance to bending or breaking under stress. These axles feature cold-rolled splines for improved strength and advanced induction coil heat treating, a process that creates a very durable axle shaft. The kit also includes Spicer U-joints and all necessary hardware, along with a vacuum disconnect block-off kit for models equipped with that feature.

This kit is built to handle demanding use, offering a substantial improvement over stock components. It's designed to fit Dana Spicer 30 front differentials with 30-spline inner axles and 27-spline outer axles, and is compatible with 3.73 and numerically higher gear ratios. You'll get two 30-spline inner axles and two 27-spline outer axles, along with 1310 series U-joints and the necessary hardware to complete the installation.
