Construction & Design
The Yukon rear axle kit is crafted from premium 4340 chromoly steel, known for its exceptional strength-to-weight ratio and resistance to bending and twisting forces. This alloy steel undergoes a cold roll forming process that enhances the spline geometry, ensuring a tight, wear-resistant fit with the differential and axle components.
Following machining, the axles receive an advanced induction coil heat treatment that hardens the surface while maintaining core toughness. This process significantly improves fatigue resistance and durability under high stress, making the axles ideal for off-road and high-performance applications.
Every axle is precision engineered to exacting tolerances, guaranteeing proper engagement with the Jeep’s drivetrain and seamless integration with factory or aftermarket gear sets.

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!
