Revolution Gear & Axle 96-04 Jeep Grand Cherokee Dana 44 Rear Koyo Bearing 4.10 Ratio Gear Package

This Revolution Gear & Axle package starts with a 4.10 gear ratio, a notable change from stock that's ideal for larger tires or heavier loads on your 1996-2004 Jeep Grand Cherokee (ZJ/WJ) equipped with the Dana 44 rear axle. The kit includes genuine Koyo bearings, known for their smooth operation and long service life, which are crucial for the precise alignment and reduced friction needed in a differential rebuild. When you're upgrading your gearing, especially for off-road use or towing, getting the right ratio is key to restoring or improving your vehicle's performance and drivability.

Rebuilding a differential is a detailed job, and this package aims to simplify it by bundling the essential components. You'll find the ring and pinion gears themselves, along with the necessary Koyo carrier and pinion bearings. These bearings are well-made and designed to handle the stresses of daily driving and more demanding off-road conditions. The 4.10 ratio is a popular choice for those looking to compensate for the added rotational mass and diameter of larger tires, helping to bring your engine's RPMs back into an efficient range at cruising speeds and improving acceleration.

This kit is designed for the Dana 44 rear axle found in specific Grand Cherokee models. While this package includes the core gearing and bearings, remember that a full differential rebuild often requires additional items like gear marking compound, a dial indicator, and sealants, which are not included here. Always refer to the manufacturer's installation instructions for the most accurate procedure and to ensure all necessary components are accounted for before you begin the installation.
