Description

The Yukon Stage 4 Jeep JK Re-Gear Kit provides a complete solution for upgrading the front and rear differentials on compatible Jeep Wrangler models. This kit is designed to enhance traction and performance by facilitating a move to a more aggressive gear ratio, specifically the 4.11 ratio included. Included in the Stage 4 kit are front and rear Yukon ring and pinion gear sets, essential Master Overhaul kits for proper installation, robust Yukon Hardcore Differential Covers for enhanced durability, and high-strength chromoly front and rear axles. The kit is specified for Dana 30 front and Dana 44 rear axle applications, and features 24 spline pinion gears. This re-gear kit is specifically designed for the Jeep Wrangler JK generation, covering model years 2007 through 2018. It is important to note that this kit excludes Rubicon models. For 2018 model year vehicles, it is crucial to confirm whether the vehicle is a JK or JL, as this kit is intended for the JK platform.
