Dana 60 vs Ford 9"

Actually if you are looking for strength the 9" is more expensive because the stock stuff is crap. You have to buy the aftermarket stuff. The Dana however is plenty beefy with factory components. You just need a spool and 35 spline axles and you are ready to go.

The Dana is heavier though and if you are using a four link or ladder bar suspension in a narrow car the Dana is going to limit how much tire you can put under the car. A 9" will allow for a larger tire as the bars can be put closer together.
