Revolution Gear & Axle 87-96 Jeep YJ/Cherokee XJ Dana 44 Rear Koyo Bearing 4.88 Ratio Gear Package

This Revolution Gear & Axle package gives you everything you need to re-gear the Dana 44 rear axle in your 1987-1996 Jeep YJ or Cherokee XJ with a 4.88 gear ratio. Inside this kit, you'll find a complete set of 4.88 ratio ring and pinion gears, along with a full installation kit featuring Koyo bearings. Koyo is a well-known name for producing durable drivetrain components, and their bearings are a solid choice for handling the stresses of off-road use and higher-performance applications.

Changing your gear ratio from the stock setup can make a notable difference, especially if you've upgraded to larger tires or plan to. A 4.88 ratio is a popular choice for Jeeps running 35-inch to 37-inch tires, as it helps bring your engine's RPMs back into a more efficient range at cruising speeds. This means better acceleration and less strain on your engine during highway driving. The ring and pinion gears are made from strong steel, and the included installation kit contains all the necessary bearings, seals, and small parts needed to properly set up your new gears. This ensures a smooth, quiet, and reliable operation of your differential.

Proper installation is key when changing your differential gears. This kit is designed to be a direct fit for the Dana 44 rear axle found in the specified Jeep models. While the kit includes all the essential components for the gear change itself, you'll want to ensure you have the proper tools and knowledge for setting backlash, pinion depth, and bearing preloads. If you're not familiar with this process, it's always a good idea to consult a professional mechanic or refer to the manufacturer's installation instructions to get the best results from your new gear set.
