Construction & Design
The Yukon Chromoly Rear Axle Kit is crafted from premium 4340 chromoly steel, a material renowned for its superior tensile strength and fatigue resistance compared to standard axle steels. The cold roll forming process used on the splines enhances the metal’s grain structure, resulting in a stronger, more durable spline interface that resists wear and deformation under heavy loads.
Additionally, the axles undergo an advanced induction coil heat treating process. This treatment hardens the surface of the axle shafts, improving their resistance to abrasion and extending service life even in the harshest off-road environments. The combination of these manufacturing techniques ensures that the axles maintain structural integrity and performance over time.
Installation & Fitment
This rear axle kit is designed as a direct fit replacement for 2018 to 2020 Jeep Wrangler JL and JT models with 3.6L V6, 3.0L EcoDiesel, and 2.0L Turbo engines. Installation requires standard axle removal procedures and can be completed by experienced mechanics or skilled DIY enthusiasts. No major modifications are necessary, as the kit meets OEM specifications for seamless integration with existing drivetrain components.
Proper installation ensures optimal performance and longevity, making it an excellent upgrade for those looking to enhance their Jeep’s drivetrain durability without compromising fitment or reliability.

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!
