Revolution Gear & Axle 96-04 Jeep Grand Cherokee Dana 44 Rear Koyo Bearing 5.13 Ratio Gear Package

When you're looking to significantly change your Jeep Grand Cherokee's gearing, this Revolution Gear & Axle package for the Dana 44 rear axle is a solid choice. What you get in this kit is a complete set of 5.13 ratio ring and pinion gears, along with a full set of Koyo bearings and installation hardware. This package is designed to give your Jeep a much lower gear ratio, which is essential if you've upgraded to larger tires or are planning on serious off-roading. The 5.13 ratio is a popular choice for those running 35-inch to 37-inch tires, helping to bring your engine RPMs back into a more efficient range at highway speeds and providing better torque for crawling over obstacles.

Revolution Gear & Axle sources quality components, and the inclusion of Koyo bearings means you're getting a well-built set known for their durability and smooth operation. These bearings are critical for the proper function and longevity of your differential. The ring and pinion gears themselves are precision-cut to ensure they mesh correctly, which is vital for quiet operation and efficient power transfer. Installing a new gear set like this is a job that requires precision and specific tools, often involving setting backlash and gear pattern correctly. It’s a significant upgrade that changes how your Jeep performs both on and off the pavement.

This kit is intended for the Dana 44 rear axle found in the 1996-2004 Jeep Grand Cherokee (ZJ and WJ models). While this package includes the essential gears and bearings, remember that a professional installation is highly recommended to ensure everything is set up correctly. You may also need additional items like differential fluid, a gear marking compound, and potentially a master bearing installation kit depending on the condition of your existing differential housing. Taking the time to do this job right will pay off with a more responsive and capable drivetrain.
