Construction & Design
This axle kit is crafted from 4340 chromoly steel, a premium alloy known for its exceptional tensile strength and toughness. The use of cold roll forming for the splines results in a more uniform grain structure, which significantly improves fatigue resistance and reduces the risk of spline failure under heavy loads.
Additionally, the induction coil heat treating process selectively hardens the axle shafts, providing a hardened surface that resists wear while maintaining a tough core to absorb impact stresses. This combination of materials and processes ensures the axles deliver long-lasting performance even in demanding off-road conditions.

The Yukon Rear 4340 Chromoly Axle Kit is designed for direct bolt-in installation on compatible Jeep Wrangler and Gladiator models from 2018 to 2023 with specified engine options. Installation requires standard axle removal and replacement procedures, with no major modifications necessary. This kit maintains factory spline count and dimensions to ensure proper fitment with existing differentials and wheel hubs.
Professional installation is recommended to ensure proper torque specifications and alignment, preserving drivetrain reliability 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!
