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

Yukon Gear & Axle is known for building tough drivetrain components, and this front axle and locker kit for your Jeep is a prime example. If you're looking to significantly upgrade the strength and capability of your Dana 30 front differential, especially for off-road use, this kit is designed to handle more abuse than stock. It includes everything you need to replace your inner and outer axles, install a robust locker, and get back on the trail with confidence.

This kit features heavy-duty 4340 chromoly axles, which are known for their high tensile strength and durability. Yukon uses advanced manufacturing methods, including cold-roll formed splines for added strength and induction coil heat treating, to create axles that stand up to demanding conditions. You also get Yukon Super Joints, which are designed to offer better angle capability and strength compared to standard U-joints, and a Yukon Grizzly Locker. The Grizzly Locker is a mechanical locker that provides 100% traction to both wheels when engaged, making it ideal for crawling over obstacles or navigating slippery terrain. This locker is designed for 3.73 and numerically lower gear ratios.

Included in this comprehensive kit are the inner and outer 4340 chromoly axles, the Grizzly Locker, Yukon Super Joints with hardware, and carrier bearings and races. It also comes with a Yukon Vacuum Disconnect Block-Off Kit, which is a nice touch for simplifying your setup. This kit is specifically designed to fit the Dana 30 front differential found in many Jeep models, including the Cherokee (XJ), Wrangler (YJ, TJ), and Grand Cherokee (ZJ). Make sure to check the specific spline counts: you'll get two 30-spline inner axles and two 27-spline outer axles.
