Product Description

The Yukon YK C9.25-F-B is a complete master overhaul kit built specifically for the Chrysler 9.25" 14-bolt front differential found in 2003-2018 Dodge and Ram 2500/3500 trucks, select 2006-2013 Ram 1500 4WD models, and the Power Wagon. Whether you're performing a ring and pinion gear swap, upgrading to a locker, or doing a full front differential rebuild after years of towing and off-road use, this kit provides every component needed to complete the job from start to finish - including the axle seals specific to this front differential design.

The "-B" suffix reflects an updated bearing specification utilizing Koyo or Timken bearings and races - both tier-1 OEM suppliers known for high load capacity and long service life in heavy-duty applications. Combined with axle seals, oil baffles and slingers, a full shim kit, ring gear bolts, pinion nut, crush sleeve, silicone, and marking compound, this is one of the most complete front differential overhaul kits available for the Ram truck platform. Always confirm your vehicle's front axle is the Chrysler 9.25" 14-bolt variant before ordering, as Ram trucks with 2WD configurations or Dana/AAM front axles require different kits.
