Now build a 9" without ANY Ford parts then the race is on. Three bearings to support the pinion against the ring gear will ALWAYS be better than two twocents
And yes it will cost about twice as much but in the end you will have a better unit.
Still have a Dana in my car though work

100% agree

iagree Build one w/ good parts and the 9" is better.

That efficiency argument is a wash. You'll never see it, unless you're in a low powered class car that needs every tiny ounce of free movement to run a number. The benefits of an aftermarket 9" far outweigh any efficiency issue.


This is all true.
