Revolution Gear & Axle 96-02 Jeep Wrangler TJ Dana 44 Rear Koyo Bearing 4.88 Ratio Gear Package

The Koyo carrier bearings included in this Revolution Gear & Axle package are known for their tight tolerances and smooth operation, which is critical when you're changing your Jeep Wrangler TJ's differential ratio to 4.88. This specific ratio is a popular choice for TJ owners who have upgraded to larger tires, typically 35 inches or more, and are looking to bring their gearing back into an optimal range for acceleration and highway cruising. This kit is designed for the Dana 44 rear axle found in many Jeep Wrangler TJs, ensuring a proper fit for the core components of your differential rebuild.

When you're changing your gear ratio, especially to a numerically higher one like 4.88, it's essential to have all the necessary parts for a successful installation. This package includes the ring and pinion gears, along with the high-quality Koyo carrier bearings. Revolution Gear & Axle sources reliable components to help you achieve the performance you're after. Changing gear ratios can significantly alter how your Jeep performs, especially off-road or when towing, and this kit aims to provide the foundational pieces for that upgrade.

Installing a new gear set and bearings is a job that requires precision and the right tools. It's important to follow the manufacturer's installation instructions carefully, which typically involve setting proper backlash, pinion depth, and gear pattern. While this kit provides the main gear components and bearings, you'll likely need additional items such as differential fluid, a gasket, and potentially a seal kit to complete the job. Consulting your service manual or a trusted mechanic is always a good idea before starting a differential rebuild.
