Yukon Gear & Axle employs advanced design techniques and premium materials to manufacture these gear sets. The gears undergo precision CNC machining to ensure exact tooth profiles and optimal contact patterns. Following machining, the components are subjected to rigorous heat treating processes that enhance strength and wear resistance, resulting in gears that withstand the stresses of demanding off-road and towing applications.
The surface finish is meticulously controlled to reduce friction and noise, contributing to a quieter and smoother drivetrain operation. Each kit is assembled with high-quality bearings, seals, and hardware included in the Master Overhaul Kits, ensuring a complete rebuild of the axle gear assemblies for reliable performance and longevity.
This Yukon Gear & Axle kit is designed for direct fitment on 2007–2011 Jeep Wrangler JK models with the 3.8L V6 engine, as well as 2012–2017 and 2018 Jeep Wrangler JK models equipped with the 3.6L V6 engine. Installation requires professional mechanical skills and proper tools to ensure correct gear mesh and preload settings. The included Master Overhaul Kits provide all necessary bearings and seals to facilitate a thorough rebuild of the axle assemblies during installation.
Re-gearing with this kit is recommended when upgrading tire size or seeking improved torque and towing capability. Proper installation will restore or enhance drivetrain efficiency and durability.
This gear and install kit is ideal for Jeep Wrangler JK owners who are:
Yukon Gear & Axle supplies hardcore drivetrain components—ring & pinion gears, axles, lockers, and differential upgrades—built for off-road and high-load performance. 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!
