Jeep Wrangler Differential Ring and Pinion - Rear - Yukon Gear & Axle - 4.88 Ratio, 24 Spline Pinion - `07-`18. Direct replacement ring and pinion set engineered for 2007–2018 JK Wrangler Dana 44 rear differentials. It restores proper gearing when upgrading tires or power.

Built by Yukon Gear & Axle, this ring and pinion pair uses high-grade steel, advanced heat treatment and a controlled gear tooth surface finish to reduce friction and manage heat under load. The 4.88 ratio with a 24-spline pinion improves acceleration and drivability for larger tires or increased torque, while matching OEM fitment for Dana 44 JK rear housings (Rubicon and non‑Rubicon). The 8.89" ring diameter and ten-bolt pattern are standard for this application; professional setup and torque procedures are recommended for correct preload and backlash.
