Ford and Spicer are identical, except the red knob that says Ford. IMO the yukons are equal in quality to Spicer/Ford, mayby slightly better if using them really hard due to the metal knob that stands up well to physically being hammered on by rocks, my D60 units have the "free" and "lock" engravings worn off from scrapping walls. Warns are for mildly used and street rigs.
