Yukon high perf ring & pinion set, Dana 44, JK Rubicon, 24-spline, 4.11 ratio

This is the Yukon 4.11 ring and pinion set, YG D44JK-411RUB, 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: 4.11
• Pinion: 24 spline
• Ring gear: 8.89 inch, 10 bolts

4.11 is numerically higher than 3.73 and lower than 4.56, so it gives moderate gear reduction within 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 4.11 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

Ring gear and pinion only. Bearings, the crush sleeve eliminator, the pinion install kit and hardware are not part of the set.

Installation

Expect around 6 hours and treat it as a job for someone who has set up gears before, or hand it to a shop.

Warranty

Yukon lists a standard one-year warranty on its ring and pinion sets and promotes a separate Y.E.S. protection plan. Check Yukon for the current terms.
