Starting with the 1.705-inch inside diameter axle bearings, this Yukon Gear & Axle kit is built to handle the demands of your 2004-2009 Dodge Durango. If you're looking to upgrade your differential for larger tires, increased towing capacity, or just to replace worn-out components, this comprehensive package has everything you need to get the job done right. It bundles a high-performance 3.90 ratio ring and pinion gear set with a master installation kit, ensuring you have all the necessary bearings, seals, and small parts for a complete differential rebuild.
