Revolution Gear & Axle 03-06 Jeep Wrangler TJ Rubicon Dana 44 Thick F+R Koyo 4.88 Ratio Gear Package

The Koyo bearings included in this Revolution Gear & Axle package are a key component for ensuring smooth, reliable operation of your Dana 44 differential. This specific 4.88 ratio gear set is designed for the 2003-2006 Jeep Wrangler TJ Rubicon, offering a significant change in gearing that's ideal for owners who have upgraded to larger tires and want to restore or improve their Jeep's on-road performance and off-road crawling capability. Changing your gear ratio is one of the most effective ways to re-gear your drivetrain after adding larger tires, bringing your engine's RPMs back into a more efficient range at cruising speeds and providing the torque needed for challenging terrain.

This package includes everything needed for a complete front and rear differential re-gear, featuring thick cut ring and pinion gears. Thick cut gears are generally stronger than standard cut gears, especially beneficial for the demands placed on Rubicon models. Revolution Gear & Axle sources high-quality components, and the inclusion of Koyo bearings signifies a commitment to durability and precision. Proper installation is crucial for any gear change; it requires careful setup, backlash adjustment, and pattern checking to ensure longevity and optimal performance. If you're looking to optimize your Rubicon's drivetrain for larger tires, this 4.88 ratio package is a well-built solution.

When undertaking a gear change, it's important to have all the necessary installation components on hand. While this kit provides the ring and pinion gears and Koyo bearings, you'll typically need additional items such as differential fluid, sealants, and potentially new axle seals, depending on the condition of your existing setup. Always refer to the manufacturer's installation instructions for detailed guidance on setup and break-in procedures to get the most out of your new gear set.
