Yukon Gear Ford 9in Differential Dropout Assembly 31 Spline 3.70 Ratio
Yukon dropout assemblies are built by expert Yukon technicians and come complete, properly shimmed and backlashed to spec.

This unit features a nodular iron case which improves rigidity and power handling, reducing deflection for consistent gear contact and a long service life.
