Rear diff question

Much like the Mopar 8 1/4, the Ford 8" is a lot stronger than people give it credit for. But, axle availability is not good, unless you go custom like Moser, Strange or Currie. Keep in mind it has three pinion bearings, much the same as a 9" and that gives it some strength.

Lastly, if you find the ribbed center section, it is very strong. I have one in the 8" housing under my Mercury Bobcat.

Here is the heavy duty extra ribbed 8" center section. A lot of people don't even realize Ford ever made one, but they did.
