Product Description

The Revolution Gear & Axle REV-JK-NON-488 is a comprehensive gear upgrade package tailored for the Jeep Wrangler JK Non-Rubicon (model years 2007-2018) equipped with a front Dana 30 and rear Dana 44 axle configuration. Offering a 4.88:1 ratio, this package is designed to enhance low-end torque, improve off-road traction, and compensate for larger tire diameters or increased load demands.

This kit includes both front and rear ring & pinion sets plus corresponding master overhaul kits (bearings, seals, hardware) - providing a full differential rebuild solution in one box. Manufactured from premium 8620 steel and matched with high-quality bearings, it delivers installer-ready durability for demanding applications.

Before installing, confirm that your vehicle is a Non-Rubicon JK with the correct axle setup (Dana 30 front, Dana 44 rear), verify spline counts, carrier breaks and current gear ratios. While the fitment is documented for 2007-18 models, coverage beyond 2018 and through 2025 is **unverified** at the time of listing. Always check compatibility with your specific build or vehicle prior to purchase.
