Part #: YA WD44JKNON-K
The Yukon Gear & Axle 4340 Chromoly Rear Axle is engineered specifically for Jeep Wrangler JK models equipped with 3.6L and 3.8L V6 engines from 2007 to 2017. Designed for non-Rubicon variants, this high-performance axle delivers exceptional strength and durability to handle demanding off-road conditions and heavy-duty use. Whether you’re upgrading your Jeep for trail adventures or enhancing its reliability for daily driving, this axle provides a robust foundation for improved drivetrain performance.
Built to withstand the rigors of off-road abuse and high torque loads, the Yukon rear axle is an ideal upgrade for enthusiasts seeking a dependable, long-lasting solution that maintains factory fitment and compatibility.
This rear axle combines advanced materials and manufacturing techniques to ensure superior performance and reliability:
The Yukon 4340 Chromoly Rear Axle is crafted from premium 4340 chromoly steel, known for its exceptional tensile strength and toughness. This alloy steel undergoes a rigorous cold roll forming process to create splines that resist deformation and wear under extreme loads. The axle shafts are then subjected to advanced induction coil heat treating, a process that hardens the surface while maintaining core toughness, resulting in an axle that resists bending, twisting, and fatigue.
Every axle is precision engineered to meet or exceed OEM specifications, ensuring a perfect fit and reliable performance. The 30 spline design increases the contact surface area within the differential, allowing the axle to handle higher torque and power outputs without failure.
This rear axle is designed as a direct replacement for the factory rear axle shafts on 2007–2011 Jeep Wrangler JK models with the 3.8L V6 engine and 2012–2017 models with the 3.6L V6 engine, specifically for non-Rubicon trims. Installation requires no modifications to the axle housing or differential components, making it a straightforward upgrade for experienced mechanics and off-road enthusiasts alike.
Proper installation ensures optimal drivetrain performance and longevity, restoring or enhancing the vehicle’s capability to handle off-road challenges and increased power demands.
This rear axle is ideal for Jeep Wrangler JK owners who demand greater strength and durability from their drivetrain components. It is especially suited for off-road enthusiasts, daily drivers upgrading from stock axles, and anyone looking to improve their vehicle’s reliability under increased torque loads or harsh driving conditions.
Yukon Gear & Axle supplies hardcore drivetrain components—ring & pinion gears, axles, lockers, and differential upgrades—built for off-road and high-load performance. Trusted by enthusiasts and installers, Yukon focuses on fit, strength, and proven options for re-gearing and reinforcing trucks and 4x4s running bigger tires and tougher terrain.
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
