Dana 60 S60 or Ford 9"

All the A/H cars run 9 inch
The 9 inch can be made plenty strong given the budget.
But a Dana can handle those kind of performance numbers no problem. The Ford may have the edge from a setup and serviceability perspective, but the point of this thread was that the Dana can match or exceed that same strength level for much less money, and the serviceability edge might be less now with the threaded adjuster on the s60. Proper pinion depth is usually the most time consuming part of setting up gears. If you know in advance what that depth is, you could swap gears in a Dana very quickly because you no longer need a case spreader.
As was said earlier it is about $1,000.00 more in cost to build the Ford and that's if you only buy one aftermarket centre section.
But I can certainly see why the Ford is more popular in certain categories.
