ford 9 inch really?
this picture will explain a lot:
basically if you look at the contact area, a ford 9" has more pinion on ring contact area than a dana 60
i knew a guy with a big block chevy pickup with foggers and stuff 4900 lbs truck he was blowing out dana 60's and had to switch to a ford 9
depending on your power and weight of the vehicle an 8 3/4 will work fine up to a point, then a dana 60 beyond that. at a certain point you will want a ford 9, depending on how violent your launches are.
i.e. if you dont have race slicks and your car doesnt hook your 8 3/4 will be all you ever need. if you are hooking and your car is not a 4000 lbs fat hog or you are not putting out 1000+ hp the dana will last just fine.
if you have a 1000hp pickup truck get a ford 9
