The Yukon Dana 300MM Rear Master Overhaul Kit is engineered to provide all the essential parts for a complete differential overhaul in a single, convenient part number.

Specifically designed for Dana 300MM differentials with a 14-bolt ring gear, this kit is compatible with 2017 and newer Ford F350, F450, and F550 Super Duty trucks. The precise fitment ensures proper function and longevity of the differential components.
