rear end question

dgt_mustang · January 20th, 2008, 06:01 PM

if a 4.6l ford gt engine was dropped into my sixer how would the 7.5 rear end hold up? wiser to get an 8.8 maybe?

Not long. Especially if you drive it hard.

You're better off with the 8.8 plus you get posi with it. The 7.5 is an open dif.

dgt_mustang · January 20th, 2008, 06:05 PM

so no matter what 8.8 rear end it is, its already got the t-lok on it?
also will a new 2006-7-8 or whichever 8.8 rear end fit? have a couple of take-off sites saved..

dgt_mustang · January 20th, 2008, 06:10 PM

o, and wat if my 7.5 rear end has t-lok

I believe ford kept the same rear end in the s197's.

And Zippy told me that MSO had a nice rear end. I don't know what's up with that....

If your 7.5 has t-loc it's not gonna matter with the power the v8's gonna give you. You'll still need a 8.8

dgt_mustang · January 20th, 2008, 06:14 PM

okay, well will a take off from one of the new models fit on my 01?

Breakout · January 20th, 2008, 06:22 PM

yes...it will. it's the same rear end used in 99-04's.

dgt_mustang · January 20th, 2008, 06:22 PM

i though take-offs were gonna be cheaper but.....nope, gotta find another one. unless anyone knows any good websites for 8.8 ends.

Breakout · January 20th, 2008, 06:24 PM

your best bet is to find a used one locally. shipping will cost a lot of $$$ if it's traveling long ways.

dgt_mustang · January 20th, 2008, 06:27 PM

good point. geuss ill try to find one at the junkyard, first time im ever hoping someone driving a mustang hit someone with the front of their car. lol

thanx for the rep points

dgt_mustang · January 20th, 2008, 06:30 PM

lol, well it was a good point, question 2, wats the exact name for an 8.8 rear end? a rear differential?

Elder · January 20th, 2008, 06:31 PM

i blew my stock 8.8 up i would suggest getting one and maybe beefing it up a bit

dgt_mustang · January 20th, 2008, 06:36 PM

are they called differentials?

Elder · January 20th, 2008, 06:39 PM

a differential is what you bolt the ring gear to which when the pinion gear spins it spins the diff in turn turning the axels which turns the wheels

dgt_mustang · January 20th, 2008, 06:42 PM

okay so what i should be looking for is an 8.8 rear end, just exactly that right?. just want to make sure before i go around askin the wrong thing.

Elder · January 20th, 2008, 06:43 PM

IMO i would get an 8.8 out of a gt and get a decent diff to go with it...you dont need to do anythin to extensive or crazy if you dont plan on pushing really large numbers

Elder · January 20th, 2008, 06:46 PM

ya you should be able to pick one up pretty cheap from a junk yard. sand blast it and paint it and it will look awesome

TheUNZippee! · January 20th, 2008, 06:48 PM

8.8 is the diameter of the ring gear in inches.

So 8.8>7.5 just due to being bigger and thus stronger.
