Yukon Gear High Performance Gear Set For Dana 44 TJ Rubicon / 5.13

If you're looking to re-gear your 2003-2006 Jeep Wrangler Rubicon Dana 44 axle, especially after adding larger tires or increasing horsepower, this Yukon Gear & Axle high-performance ring and pinion set is a solid choice. This set features a 5.13 ratio, which is ideal for bringing your engine's RPMs back into an efficient range when running bigger rubber, improving acceleration and drivability.

Yukon engineers focus on quality, using high-grade steel for both the ring and pinion gears. They've also paid attention to the gear tooth surface finish, which is designed to reduce friction and heat. This is important for longevity, especially under high torque conditions or during extended use. The fitment is designed to OEM specifications, meaning it should install correctly into your Dana 44 TJ Rubicon axle housing. Yukon also backs these gears with a 1-year warranty against manufacturing defects, and offers an optional Y.E.S. Plan for lifetime coverage.

When installing a new ring and pinion set, it's crucial to follow the manufacturer's break-in procedure to ensure proper seating and longevity. This typically involves a period of gentle driving with no hard acceleration or heavy loads, followed by an oil change. You'll also need a master installation kit, which includes bearings, seals, and shims, as these are not part of the gear set itself.
