Whats the difference between the two center sections? I have one of each and but wondering if either is stronger?
I like my solid sleeved 489s :twisted:
The 489 has a thicker pinion, but all the 3 types all neck down to the same size near the splines.
And when they break, the bearings caps and ring gear teeth are the first to go. Usually not the pinion.
You think you're making enough power to break one?

1000hp ... And you are even considering a 8.75???
Do not pass go, do not collect $200
ditch the 8.75 stuff and get a dana60 or 9"
