Revolution Gear & Axle 87-96 Jeep YJ/Cherokee XJ Dana 44 Rear Koyo Bearing 4.56 Ratio Gear Package

This package from Revolution Gear & Axle gives you everything you need to install a 4.56 ratio ring and pinion gear set into the Dana 44 rear axle found in 1987-1996 Jeep YJ Wranglers and Cherokee XJs. Inside this kit, you'll find a set of 4.56 ratio gears, a complete Koyo bearing and seal kit, and all the necessary installation hardware. This is a comprehensive solution for anyone looking to change their differential gearing for improved performance, especially when running larger tires.

The gears themselves are made from strong, well-built steel, heat-treated for durability and designed for reliable power transfer. Revolution Gear & Axle includes a full Koyo bearing and seal kit, which is a popular choice for its smooth operation and long service life. Koyo bearings are known for their tight tolerances and consistent performance, which is crucial for a properly set up differential. This kit also comes with all the small parts you'll need for the installation, like crush sleeves, pinion nuts, and marking compound, so you can be confident you have what it takes to get the job done right.

Changing your gear ratio to 4.56 is a common upgrade for Jeeps running 33-inch or larger tires. This ratio helps bring your engine RPMs back into a more efficient range at highway speeds, improving drivability and reducing strain on your drivetrain. Proper installation is key for the longevity of your new gears, so be sure to follow the manufacturer's instructions carefully, paying close attention to backlash and pattern setup.
