Revolution Gear & Axle 96-04 Jeep Grand Cherokee Dana 44 Rear Koyo Bearing 4.88 Ratio Gear Package

This is the Revolution Gear & Axle 4.88 ratio gear package specifically for the Dana 44 rear axle found in 1996-2004 Jeep Grand Cherokees (ZJ and WJ models). If you've upgraded your tires to a larger size or are looking to improve your Jeep's performance off-road or when towing, changing your ring and pinion gears to a lower ratio like 4.88 can make a significant difference. This package includes everything you need to get that new gear ratio installed correctly, featuring high-quality Koyo bearings for smooth operation and long life.

Choosing the right gear ratio is crucial for getting the most out of your Jeep's drivetrain. A 4.88 ratio is a popular choice for Grand Cherokees with 35-inch or larger tires, as it helps bring your engine's RPMs back into an optimal range for highway driving and improves acceleration. This kit comes with a complete set of gears and the necessary Koyo bearing kit, which is known for its durability and precision. Revolution Gear & Axle is a well-known name in the differential parts industry, and this package is put together to ensure a solid installation for your Dana 44 rear end.

When installing a new ring and pinion gear set, it's important to follow the manufacturer's break-in procedure carefully to ensure the gears mesh properly and achieve their maximum lifespan. This typically involves a period of moderate driving without heavy loads, followed by oil changes. This package is designed to be a comprehensive solution for your gear change, but always refer to the installation instructions provided by Revolution Gear & Axle for specific details on setup and break-in.
