Yukon Gear 4340 Chrome-Moly Replacement Axle Kit For Jeep TJ / YJ & XJ Dana 30 / w/ Super Joints

Yukon Gear & Axle is known for making strong drivetrain components, and this front axle kit for your Jeep Wrangler is a prime example. If you're looking to beef up your Dana 30 differential for off-road use or just want a more durable replacement for worn-out factory axles, this kit is built to handle the demands. It includes everything you need to replace both the inner and outer axle shafts on the front of your Jeep.

This kit uses 4340 chromoly steel, which is a well-known material for its high tensile strength and toughness, making it a popular choice for performance axles. Yukon also uses cold roll formed splines, a method that strengthens the spline area without removing material, and advanced induction coil heat treating to ensure consistent hardness and durability throughout the axle. This process helps create a solid axle that can withstand more stress than stock components. The kit also comes with Yukon's Super Joints, which are designed to offer a greater range of motion and improved strength over traditional U-joints, especially important when you're flexing your suspension off-road. You'll also find a vacuum disconnect block-off kit included, which simplifies your front axle setup.

This kit is designed as a direct replacement for the Dana 30 differential found in many Jeep models. It includes both the left-hand and right-hand inner axles, as well as the two outer axles, all featuring 27 splines. Make sure to check the fitment details to confirm it matches your specific Jeep year and model.
