Anyone install one of these. Are they that much better than the 12 bolt to warrant the price. How was the ease of install?

 

thats all nice and they are strong, but for the ease of gear change and the known strength, i'd get the 9" ford. it's been proven for a long time that it's worth buying.

 

To warrant the price? Last I checked they were actually cheaper than the 12 bolt...

 

Lightest to Heaviest: 12 bolt, 9 inch, S60

Weakest to strongest: 12 bolt, 9 inch, S60

Ring Gear: 12 bolt 8.875", 9 inch 9" (duh!) S60 9.75"

The 12 bolt and 9 inch come with a 33 spline posi, the S60 is a 35 spline unit. There are alot of posts comparing the weights and parasitic loss %s around boards like this and ls1tech.

 

unless your going for major power, if go with 12 or 9inch...

 

Get the S60,its a waste of effort to ship a lesser rear end all the way to Honolulu.

 

Try a "Search" to uncover threads regarding excessive noise problems with the Strange-60.

 

Is it confirmed and proven that the Dana 60 is stronger than a 9"? Or Was it just assumed that it's stronger just for having a larger ring gear. How much does having the lower pinion placement and 3 bearing support of pinion contribute to the 9" strength?

 

theoretically, the s-60 is stronger. but many guys run 9" rears right into the 8's. i don't think any of us are shooting for 8's. plus, there are soo many parts for 9" fords. aluminum cases are even decently cheap.
