Jeep JK Differential Install Kit - Front + Rear - Yukon Gear & Axle - Stage 4, 5.13 Ratio - `07-`18

Jeep JK Differential Install Kit - Front + Rear - Yukon Gear & Axle - Stage 4, 5.13 Ratio (2007-2018). A complete re-gear and axle upgrade bundle for JKs equipped with front and rear Dana 44s (YGK016STG4).

This Stage 4 package combines Yukon 5.13 ring and pinion sets with Master Overhaul Kits, 4340 chromoly front and rear axle shafts, and nodular iron Yukon Hardcore diff covers. Yukon’s advanced design, heat-treating, and quality testing ensure precise fit and finish, while the 5.13 ratio helps recover torque with larger tires and improves low-speed control off-road. Kits include bearings and small parts for a full rebuild, and Yukon’s Y.E.S. Plan adds lifetime, no-questions-asked coverage to the gear set kit.
