Revolution Gear & Axle 03-06 Jeep Wrangler TJ Rubicon Dana 44 Thick F+R Koyo 5.38 Ratio Gear Package

If you've got an 03-06 Jeep Wrangler TJ Rubicon and you're looking to significantly change your tire size or gearing for off-road performance, this Revolution Gear & Axle 5.38 ratio gear package is a solid option. This kit is specifically designed for the Dana 44 axles found in the Rubicon model, both front and rear, and includes Koyo bearings, which are well-known for their durability. Going to a 5.38 ratio is a popular choice when upgrading to larger tires, typically 37 inches or more, as it helps bring your Jeep's performance back to a stock-like feel by compensating for the increased rotational mass and diameter. This means better acceleration, improved drivability on the highway, and less strain on your drivetrain.

This package includes everything you need for a complete gear change on both axles. You'll find the thick cut ring and pinion gears, which are designed for the Dana 44 housing and offer improved strength over standard cut gears, especially under heavy load. The inclusion of Koyo bearings is a notable detail; these bearings are manufactured to tight tolerances and are built to handle the stresses of off-road use. Proper installation is key for any gear set, and while this kit is comprehensive, it's recommended to consult a professional installer or follow the manufacturer's detailed instructions to ensure the gears are set up with the correct backlash and pattern for optimal performance and longevity. This gear set is a significant upgrade for Rubicon owners looking to maximize their Jeep's capability with larger tires.
