Revolution Gear & Axle 07-18 Jeep Wrangler JK Non-Rubicon Koyo Bearing 4.10 Ratio Gear Package

This Revolution Gear & Axle package uses Koyo bearings, a well-known name in drivetrain components, for your 2007-2018 Jeep Wrangler JK. The 4.10 gear ratio is a popular choice for JK owners looking to improve performance, especially after installing larger tires. This ratio offers a good balance, providing better acceleration and pulling power than stock, while still maintaining reasonable highway cruising RPMs.

When you're upgrading your differential gears, using high-quality bearings is crucial for smooth operation and long-term durability. Koyo bearings are manufactured to tight tolerances, ensuring they mesh perfectly with the new ring and pinion gears. This kit is specifically designed for the Non-Rubicon JK models, meaning it's intended to replace the factory gears in the Dana 30 front and Dana 44 rear axles. Proper installation is key to getting the most out of this gear set; it's recommended to have a qualified technician perform the installation, as it involves setting backlash and pinion depth correctly.

This package includes the ring and pinion gears, along with the necessary Koyo bearings to complete the installation. While this kit provides the core components for a gear change, remember that a professional installation typically requires additional items like gear marking compound, RTV sealant, and potentially new axle seals. Ensure you consult the manufacturer's installation instructions for a complete list of requirements and procedures.
