OK,

im ordering my parts soon to re-vamp my rear end.

i am keeping my light 7.5 rear throwing the Trak-lok and 4.10s for my auto.
im not going to do much more than bolt ons so i feel like the trak-lok is fine.

my concern is the RPMs at roughly 70 mph.

the auto has the OD running at .7 gear ratio which should put me at roughly 2500 rpms at 70 correct?

just want to confirm all of this before i buy 4.10s and have to hum at 3000 all the way to school every time i come home from break.

thanks guys.
