Jeep Wrangler Differential Ring and Pinion Gear Set - Rear - Yukon Gear & Axle - 4.11 Ratio for Dana 44 JK - '07-'18. A direct-fit, high-performance ring and pinion set engineered for the Dana 44 rear axle in JK Wranglers to support larger tires and higher torque demands.

This Yukon Gear & Axle set is built with heat-treated, high-grade steel and manufactured to OEM fitment specs. Yukon’s engineered tooth surface finish reduces friction and heat during heavy loads, helping the gears run cooler and last longer. The 4.11 ratio is a common choice for drivers who have increased tire diameter or added power and want improved acceleration and drivability without drastic top-speed changes. The set is intended for the Dana/Spicer 44 rear axle used on 2007–2018 JK models and is compatible with both Rubicon and non‑Rubicon configurations where a thick ring & pinion is required.
