Revolution Gear & Axle 03-06 Jeep Wrangler TJ Rubicon Dana 44 Timken Bearing 4.56 Ratio Gear Package

This Revolution Gear & Axle package gives you everything you need to re-gear the Dana 44 differential in your 2003-2006 Jeep Wrangler TJ Rubicon with a 4.56 ratio. You'll get a complete set of high-quality Timken bearings, which are well-known for their durability and smooth operation. This kit also includes the ring and pinion gears themselves, precision-cut to provide that 4.56 ratio. This is a significant change from the stock gearing, designed to better accommodate larger tires and improve your Jeep's performance off-road or on the highway.

Choosing the right gear ratio is crucial, especially if you've upgraded to larger tires. A 4.56 ratio is a popular choice for TJ Rubicon owners running tires in the 33-inch to 35-inch range. It helps bring your engine's RPMs back into a more efficient and powerful operating band, improving acceleration and reducing strain on your drivetrain. The Timken bearings included in this package are a solid choice, offering excellent load-carrying capacity and longevity, which is essential for the demanding environment of a Jeep differential. Revolution Gear & Axle is a well-known name in the drivetrain industry, and this package reflects their commitment to providing reliable components.

When installing a new gear set, it's important to follow the manufacturer's break-in procedure carefully. This typically involves a period of moderate driving with specific speed and acceleration limits, followed by an oil change. This process allows the new gear teeth to properly seat against each other, ensuring optimal performance and a long service life. While this kit contains the core components for a gear change, you'll also need to source or have on hand items like differential fluid, RTV sealant, and potentially a new pinion seal and crush sleeve, depending on the condition of your original parts. Always refer to the specific installation instructions provided by Revolution Gear & Axle for the most accurate guidance.
