Part #: YA WD44JKRUB-L-K
The Yukon Gear & Axle 4340 Chromoly Rear Left Axle is a high-performance replacement axle designed specifically for Jeep Wrangler JK models from 2007 through 2018 equipped with 3.6L or 3.8L V6 engines. Engineered to meet the demanding needs of off-road enthusiasts and daily drivers alike, this axle delivers superior strength and durability to handle increased torque and rugged terrain. Whether you are upgrading for enhanced reliability or replacing a worn factory axle, this Yukon axle offers a dependable solution built to last.
Ideal for Rubicon models, this axle ensures optimal compatibility and performance, maintaining factory fitment while providing the toughness required for extreme off-road conditions. Its 32 spline design and precise 31.25-inch length make it a direct fit for the rear left side, simplifying installation and minimizing downtime.
Yukon Gear & Axle incorporates advanced manufacturing techniques and premium materials to deliver an axle that stands out in quality and performance. Key features include:
This rear left axle is crafted from premium 4340 chromoly steel, a material known for its superior tensile strength and fatigue resistance. The use of chromoly ensures the axle can withstand the stresses of off-road driving and high torque without bending or breaking. The cold roll forming process used on the splines enhances their strength by aligning the grain structure, resulting in a more durable and wear-resistant spline interface.
Additionally, the axle undergoes an advanced induction coil heat treating process, which hardens the surface while maintaining a tough core. This treatment improves resistance to abrasion and impact damage, extending the service life of the axle under demanding conditions. The precise engineering and quality control ensure consistent dimensions and fitment, making this axle a reliable upgrade or replacement part.
The Yukon 4340 Chromoly Rear Left Axle is designed as a direct bolt-in replacement for the rear left side of Jeep Wrangler JK Rubicon models from 2007 to 2018 with 3.6L or 3.8L V6 engines. Its exact 31.25-inch length and 32 spline count match factory specifications, allowing for straightforward installation without the need for modifications or additional machining.
Installation should be performed by a qualified technician or experienced enthusiast familiar with axle replacement procedures. Proper torque specifications and alignment checks are recommended to ensure optimal performance and longevity. This axle is compatible with stock and many aftermarket differential setups commonly used in Jeep Wrangler JK applications.
This axle is perfect for Jeep Wrangler JK owners seeking a durable, high-strength rear left axle for their Rubicon equipped with 3.6L or 3.8L V6 engines. It suits off-road enthusiasts who demand reliability in challenging terrain, as well as those upgrading their drivetrain for increased torque capacity. Additionally, it is an excellent choice for anyone needing a direct-fit replacement axle that meets or exceeds OEM standards without compromise.

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!
