Yukon YGK057 Re-Gear Package - 3.73 Ratio

Take all the guesswork of regearing your 2003-2011 Dodge Ram 2500/3500 with the Yukon YGK057 3.73 Re-Gear Package. The master overhaul kits exclusively use Timken bearings and include everything necessary to install your new gear sets. Yukon backs their ring & pinion kits with a 1 year warranty. Yukon combines a front and rear 3.73 ring & pinion set along with the most complete master overhaul kits on the market, giving you everything needed to re-gear the front and rear differential under one easy part number. Yukon tests each ring and pinion set on a roll stand to make sure the fitment is perfect.

Fits C9.25" Reverse Front Differential and  AA14-11.5" Rear Differential. 

In mid 2011 the design for the pinion bearing changed. 

The early design had a rear pinion race O.D. of 4.125" with a bearing part number HM807046. The later design has an O.D. of 4.375" with a bearing part number NP516549. 

This kit fits the early design.
