Revolution Gear & Axle 96-04 Jeep Grand Cherokee Dana 44 Rear Koyo Bearing 4.56 Ratio Gear Package

If you're looking to change the gear ratio in your 1996-2004 Jeep Grand Cherokee with a Dana 44 rear axle, this 4.56 ratio gear package from Revolution Gear & Axle is a solid option. This kit is designed to give you a noticeable improvement in acceleration and towing power, especially if you've added larger tires. The 4.56 ratio is a popular choice for off-roaders and those who frequently tow, as it helps bring your engine's RPMs back into a more efficient range at highway speeds after a tire upgrade.

This package includes a set of high-quality 4.56 ratio ring and pinion gears, along with a complete Koyo bearing installation kit. Koyo is well-known for making durable bearings that can handle the stress of daily driving and off-road use. The ring and pinion gears themselves are precision-cut to ensure smooth operation and efficient power transfer. Revolution Gear & Axle is a trusted name in drivetrain components, and this kit is built to last. Proper installation is key with any gear change, so make sure you follow the manufacturer's instructions carefully, including the break-in procedure, to ensure longevity and optimal performance.

When installing a new gear set, it's important to have all the necessary tools and supplies on hand. This kit focuses on the gears and bearings, so you may need to source additional items like gear marking compound, RTV sealant, and potentially a new differential cover if yours is damaged or you want to upgrade. Taking the time to do the job right will pay off with a quieter, more reliable drivetrain.
