Yukon high perf ring & pinion set, Dana 44, JK Rubicon, 24-spline, 4.56 ratio

This is the Yukon 4.56 ring and pinion set, YG D44JK-456RUB, for the rear Dana 44 in 2007-2018 Jeep Wrangler JK models, with a 24-spline pinion.

Fitment

• Vehicle: 2007-2018 Jeep Wrangler JK, rear axle (Yukon's listing names the Rubicon)
• Axle: Dana Spicer 44, rear
• Ratio: 4.56
• Pinion: 24 spline
• Ring gear: 8.89 inch, 10 bolts

4.56 is a deeper gear than 4.11 and shallower than 4.88 in this group of JK rear sets.

Check before you order

• This is the rear set. The Rubicon front Dana 44 uses a reverse rotation, short pinion set instead (the D44RS series), so it is not a match for the front.
• Front and rear ratios have to match. If the front axle is already geared to 4.56 you are set, otherwise plan to do both.
• Confirm the rear axle is the Dana 44 with a 24-spline pinion before you buy.

What's included

You are buying the gear pair. Bearing kit, pinion install kit and mounting hardware come separately.

Installation

One retailer estimates about 6 hours and calls for mechanical expertise or professional installation. Setting pinion depth, backlash and contact pattern correctly is what makes the job.

Warranty

Yukon puts a one-year warranty on its ring and pinion sets and also describes a Y.E.S. plan that covers the gear set. Confirm the details with Yukon.
