Yukon Dana 44 Reverse Rotation Master Overhaul Kit for Jeep JK Rubicon
YK D44-JK-REV-RUB
The Yukon Dana 44 Reverse Rotation Master Overhaul Kit includes the bearings, races, seals, shims, and installation hardware needed to rebuild or regear the front differential in a 2007–2017 Jeep Wrangler JK Rubicon. Designed specifically for the factory reverse rotation Dana 44 front axle, this kit provides the major service components needed when replacing worn bearings, installing new ring and pinion gears, or rebuilding a heavily used front differential.
Large tires, lower gear ratios, and aggressive trail riding put additional stress on the JK Rubicon's front axle, making proper differential setup especially important. This Yukon kit includes premium Timken bearings and races, axle seals, and the hardware needed to establish correct pinion preload, ring gear backlash, and gear contact pattern. It's a practical choice for rock crawlers, trail Jeeps, and daily-driven JK Rubicons that need a reliable front axle rebuild.

FAQ
What Jeep models does this Yukon master overhaul kit fit?
This kit is designed for 2007–2017 Jeep Wrangler JK Rubicon and Wrangler Unlimited JK Rubicon models equipped with the factory Dana 44 reverse rotation front axle.
What is the difference between a reverse rotation Dana 44 and a standard Dana 44?
The JK Rubicon front axle uses a reverse rotation, high-pinion ring and pinion configuration. This differs from standard rotation Dana 44 axle designs, and the differential components must match the specific axle configuration. This kit is designed for the JK Rubicon reverse rotation front axle.
Does this overhaul kit include Timken bearings?
Yes. The kit includes premium Timken carrier bearings, pinion bearings, and matching races for the front differential.
Are axle seals included in this kit?
Yes. Inner axle seals and the pinion seal are included, allowing worn seals to be replaced while the differential is disassembled.
Should I use a master overhaul kit when regearing my Jeep JK Rubicon?
Yes. We recommend replacing bearings, races, seals, and setup components when installing a new ring and pinion, especially on a high-mileage or heavily used axle. Proper bearing preload, backlash, and gear contact pattern are critical for reliable operation and long-term gear life.
Will this kit fit a non-Rubicon Jeep JK?
Not if it still has the factory Dana 30 front axle. This kit is designed for the Dana 44 reverse rotation front differential found in JK Rubicon models. Modified or axle-swapped vehicles must be checked against the actual axle configuration.
Does this kit include ring and pinion gears?
No. This is a master overhaul and installation kit. Ring and pinion gears are sold separately so you can select the correct ratio for your Jeep and tire size.
