Revolution Gear & Axle 07-18 Jeep Wrangler JK Non-Rubicon Koyo Bearing 5.38 Ratio Gear Package

If you've upgraded your Jeep Wrangler JK's tires to a larger size, or if you're planning to, changing your differential gear ratio is a smart move. This Revolution Gear & Axle package is designed for 2007-2018 Jeep Wrangler JK models that do not have the factory Rubicon package. The 5.38 ratio is a popular choice for significantly larger tires, helping to bring your Jeep's performance back to where it should be by improving acceleration and bringing your engine RPMs back into a more efficient range on the highway. This kit includes everything you need for a proper differential rebuild, featuring high-quality Koyo bearings, which are well-known for their durability and smooth operation.

Revolution Gear & Axle has put together this package to make the process of re-gearing your differentials more straightforward. By including the Koyo bearing kit alongside the precision-cut ring and pinion gears, they ensure that you have the essential components for a solid installation. Proper gear installation is critical for the longevity and performance of your drivetrain, and using quality bearings like those from Koyo is a key part of that. This kit is intended for the non-Rubicon JK models, so be sure to confirm your Jeep's original equipment before ordering.

When tackling a gear change like this, it's important to have all the necessary supporting components. While this kit provides the gears and bearings, you'll also need to source items like differential fluid, RTV sealant, and potentially a master install kit if it's not included with the bearings (always check the contents list). Taking the time to properly set up your new gears is crucial for optimal performance and to avoid premature wear. Refer to the manufacturer's installation instructions for detailed setup procedures.
