Pinion Comparison - Quality Body Shop Drivetrain

Less all read from the Dr Diff web site about the 9”:
“Notice, the popular Ford 9″ uses the smallest pinion shaft of the bunch.” Referring to the full range of pinions in a picture comparing 741, 742, 489, 12 bolt 9” and Dana 60 I believe. Dr Diff is well respected in our community from what I see.

Lol! People use the 9” because they are cheap, plenty full and you can get parts everywhere. They are recreated by aftermarket companies by the dozen. Let’s look at it from another angle... the Ford 9” is no different in popularity than the small block Chevrolet and that’s being replaced by a LS motor. But you chose a MoPar, with a Mopar engine... not an LS or Chevrolet engine for a reason.

say what you want but 8-3/4 rears are top shelf in my book. And less weight than a Dana 60. I hope the OP understands I hope what ever rear axle he/she chooses for this monster engine they are building it is ultimately their choice and I wish them the best no matter what rear they chooses. And where are the pictures? All this text and not one picture?
