What are the differences between the 9 and 10 bolt rear ends? Which is stronger? And don't say 1 bolt. LOL

 

actualy the 9 bolt is stronger because its ring gear is 7.75" when the ten bolts ring gear is only 7.5" or 7.625"
the 9 bolt also does not use c-clips to hold the axles in which also make it better choice for drag racing
9 bolts are better but you must also take into account price and avalibility of parts
i have a 9 bolt and i have only found 1 place online that sells a new posi for it and it is $550 but 10 bolt posis are very avalible in many different styles and kinds and cost half as much
and all the rest of the parts for a 9 bolt are hard to find as well and costs more
so you have to think
strangth or price
its your call
i plan to built a 12 bolt for my car

 

9 bolt is stronger, but parts are more rare and expensive.

 

What years were they available? ...With automatics or 5-speeds or both?

 

It's all on my page at www.9bolt.com I have brand new posi units available for 445, gear sets to 4.10 and other stuff.

Check the FAQS section for reasons the 9 bolt is much stronger.
