This package from Revolution Gear & Axle gives you everything you need to install a new 4.56 gear ratio in the Dana 44 thick front and rear differentials for your 2003-2006 Jeep Wrangler TJ Rubicon. You'll receive a complete set of Koyo ring and pinion gears, along with all the necessary installation hardware and bearings to get the job done right. This is a significant upgrade for Rubicon owners looking to optimize their drivetrain for larger tires or specific off-road applications.

Revolution Gear & Axle is known for putting together solid packages, and this one is no different. They've paired Koyo gears, which are well-regarded for their strength and precision, with a full kit of installation components. This means you're not just getting gears; you're getting a comprehensive solution. The 4.56 ratio is a popular choice for TJ Rubicon owners who have moved up to 35-inch or 37-inch tires, as it helps bring your engine's RPMs back into a more efficient and powerful range on the highway and during off-road crawling. This kit is designed to fit the Dana 44 'thick' differential found in the Rubicon models, ensuring proper setup and performance.

When undertaking a gear change like this, it's important to have all the right pieces. This kit aims to provide that, but always refer to the manufacturer's installation instructions for specific details on setup, backlash, and any specialized tools you might need. A proper gear installation is critical for long-term durability and performance, so taking your time and following the procedures is key.
