Construction & Design
The Yukon Gear Chromoly Rear Axle is crafted from premium 4340 chromoly steel, known for its exceptional tensile strength and toughness. This material choice ensures the axle can withstand the stresses of off-road driving and high torque loads without bending or breaking. The splines are cold roll formed, a process that enhances the metal’s grain structure for improved strength and fatigue resistance compared to cut splines.
Additionally, the axle undergoes advanced induction coil heat treating, a precise thermal process that hardens the surface while maintaining a tough core. This treatment improves wear resistance and extends the service life of the axle under harsh conditions. The 29 spline count provides a larger contact area for torque transfer, reducing the risk of spline failure during demanding use.
Installation & Fitment
This rear axle is designed as a direct fit replacement for the rear differential of 2018 and 2019 Jeep Wrangler JL models equipped with 3.6L V6 or 2.0L Turbo engines. Installation requires standard axle removal and replacement procedures, with no modifications necessary to the axle housing or surrounding components. Professional installation is recommended to ensure proper torque settings and alignment for optimal performance and safety.

What does the Available to Promise date mean?
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!
