Revolution Gear & Axle 03-06 Jeep Wrangler TJ Dana 44 Rear Koyo Bearing 5.13 Ratio Gear Package

If you're looking to significantly increase the tire size on your 2003-2006 Jeep Wrangler TJ with a Dana 44 rear axle, installing a lower gear ratio like 5.13 is a common and effective way to bring back lost acceleration and drivability. This gear package from Revolution Gear & Axle is designed to help you achieve that goal, making it a solid choice for serious off-road builds or if you're running larger tires for highway cruising.

This kit centers around a 5.13 ratio ring and pinion gear set, which is a popular choice for TJ Wranglers running 37-inch or larger tires. The package also includes a full set of Koyo bearings, which are well-known for their durability and smooth operation. Koyo is a respected name in bearing manufacturing, and using their components helps ensure a long service life for your differential. Revolution Gear & Axle is known for providing well-built gear sets, and this package aims to give you the core components needed for a successful gear swap. Remember that a gear change like this often requires recalibrating your speedometer to ensure accurate readings.

When undertaking a gear change, it's important to have all the necessary installation components. While this package provides the essential ring and pinion gears and Koyo bearings, you'll typically need additional items such as differential fluid, sealants, and potentially new axle seals or a master install kit depending on the condition of your existing components. Always refer to the manufacturer's installation instructions for the most accurate guidance on the process and any other recommended parts.
