The Revolution Gear & Axle REV-JK-NON-488-K Gear Package is a complete re-gear solution engineered specifically for **2007-2018 Jeep Wrangler JK Non-Rubicon** models equipped with a **Dana 44 rear and Dana 30 front differential**. This matched package includes both front and rear ring & pinion gear sets with a **4.88 ratio**, paired with premium **Koyo bearings** and master install kits to facilitate a full differential overhaul. High-grade 8620 steel gears undergo precision heat treatment and lapping processes to ensure smooth operation, strength, and lasting durability for street, trail, or heavy-use driving.

Each gear set includes comprehensive master overhaul components such as bearings, seals, shims, and all necessary hardware to help achieve proper backlash, preload, and optimal gear pattern during installation. When upgrading from the factory **3.21 ratio**, a front carrier may be required to adapt to the new gear set.
