Its more about the weight of the car and the power you run..
this have been discussed many times over... myself I run a 8 3/4
in one car and a 9" in the other.. the 8 3/4 in the race car BUT
its light.. and the 9" in my street rod.. they all have there place..
if you go with either I would recommend a back brace on them.. load
bolts help the 8 3/4... also a MW cap on the load side helps

We all know that there is a larger gear selection for the 9"
but lets hear some FACTS on what he has before we get carried
away at spending HIS money.. sounds like he has a 8 3/4 now but
we know nothing..... so to the OP.. what do you have.. fill in
some blanks here

i have both in my cars, both are good products but the 9" has more options available, more choice of cases, more choice in gears more choice in spools & more choice in lockers. Both the 9" & the 8 3/4 have the same stock case weak link, the bearing caps are weak. if you're going racing i'd go with the 9", if you're just a streeter, then the 8 3/4 will be just fine.

9" is a good bit stronger. There are more parts available for it also.

Either one of these can be made better but then it won't be cheaper.


In theory, there is no difference between theory and practice. In practice, there is.

What car and what is the application? I'm guessing you already have the 8.75? If I was starting a project from scratch and didn't have either, I'd probably go w/ a 9". BUT if I had a running driving car w/ a 8.75 I'd stay with that.

Oohhhso you come here to start fight.
Finish him.
Seriously though you should give intended use and power weight of car manual or automatic transmission with our without trans brake.. Maybe you need a Dana 60 instead.

If I had to set one up it'd be the 9"....pinion depth changes are a lot easier.

no, no BS starter here just looking for opinions on the 2 different rears.
i am in the process of building a Duster with a 511 BB, 727 trans and have a 8 3/4 being narrowed for the rear.

If you are spending the cash to narrow an 8 3/4 I would consider a Dana and be done.
