If you're going to add in gears, get a posi as well.

I think he was looking for Ford Racing brand gears...

 

Yea, i know about posi lock and all that, just wanna find FRPP specific gears :P

 

Motive = FRPP gears

 

Are they the same, just different name? Or is it a diff manufacteur?

 

It's the same ****. Why are you concerned with the brand? Motive puts out a pretty solid gear.

 

Idk people always say to get FRPP and nothing else.

 

Motive is pretty much the same stuff. If it wasn't worth a damn, I wouldn't recommend it lol.

 

K cool.

 

Im glad AM finally put an affordable posi on their site.
For a while they only had an 8.8 rear end posi that was like..$500.
Now they have one for the 7.5 and its only lke...250, I think.

 

A little 7.5 posi shouldn't be an arm and a leg regardless... if you got the power to break a 7.5 posi then you prolly got the cash to buy an 8.8

And I think the 8.8 posi that was 500 was a detroit tru trac..which..is a pretty badass posi lol..

 

Cant remember the brand.
All I remember is saying "**** that. Too much money."
And didnt wanna have to buy an 8.8 rear end either.
But Im starting my new job her in a couple days, and Im going to start saving for a posi and 4:10s. Should only need about 500 all together including the rebuild kit and the install.

 

Speaking of breaking the posi.......I heard from a local shop that a 7.5 Trac-lok will break if you burnout a lot and do hard starts and shifts, that old hard driving thing basically. Anybody want to share experience on the durability of a 7.5 Trac-lok/gears and ****?

 

Burnouts are not going to break a posi, they will wear the clutches, but so does just daily driving. If you make over 300rwho and have sticky tires then I would worry about the 7.5" breaking.

 

like dustin said unless your making power from a s/c or nitrous with some stickys you got no problem with the 7.5

 

Noted. Thanks for the info Spike

they make em

 

can i put on a 8.8 posi on a v6? or will i only be able to use a 7.5 b/c im looking into getting 4.10 gears and im not sure which posi will be the best choice? thanks

 

You can put an 8.8 on a v6.

 

As long as you are talking about installing a full 8.8 rear end from a GT then yes its a straight swap from the 7.5 to the 8.8, however if you mean just the posi unit then no you can not do that. Because the 7.5 cases is smaller then the 8.8 rear end.

 

where can i find a full 8.8 rear end?

 

they have 8.8 cases on AM, so could i do that get the 8.8 posi with a case would that fit? or do i just need a whole new rear end with a 8.8?

 

I believe the internals on the 7.5 and 8.8 are completely different, you will need an entire rear end. You can find them used on ebay, craigslist, etc.

 

V6mustangstuff.com sells 8.8 rearends with gears in it allready. Grant the one with 410s is kinda expensive but a 8.8 with 3.31 with only 20 miles on it is like 550. Check it out. under GT take off parts.

 

i checked out that site but i have a 99, those rearends are for 05 and up..damn

 

I'd probably check out local junkyards, craigslist, ebay.. shipping on a rear end is an arm and a leg (i did that about a month ago)

And you can go with an old SN95 rear end, or a new edge rear, only issue with the sn95 is it is slightly shorter then a new edge..but will work just fine.

PCola is right, you can't just throw on a housing, you need an entire new rear end.

TBH though, if you aren't pushing over 250 RWHP you should be fine with a 7.5 most of the issues with breaking them are the posi's .. under 250 RWHP on drag radials isn't enough to hurt an axle (most of the time) and if you buy a good posi, it should hold up just fine.

 

Also, if you can get to Charolette, NC my port/polish guy is selling a built 7.5 for 325, pickup only.
