Hi all!

I wanted to install on my V6 2005 mustang the 3.73 Ford Racing gears.
they have advised me to install a lsd differential.

What differential do you recommend?
I've seen this, how does it look?

Auburn Gear HP Series 7.5in 28 Spline Mustang Limited Slip Differential 542023 (79-85 V8; 86-10 V6) - Free Shipping

Thanks!!

It would be a lot better to just get a 8.8" rear with gears already installed and just swap the axle's. The new 8.8" is from FRPP (Ford racing) so it already has upgrades in it.

I live in Italy, and ship this is very expensive!

Ford no longer makes a locking differential for the 7.5 anymore so they are scarce - very few aftermarket options. It will take some searching to find anything. Make sure whatever you get is for the 31 spline axles and not the 28

31 spline axle? I tought the 2005 v6 Was 28 spline axle :-/

JimC

You are correct, mental slip.

Make sure it is a 28 spline and not the 31 spline if you find a 7.5 carrier.

JimC

You know I was thinking about it again - and I think that I was right the first time. The older 7.5 was a 28 spline, but the 2005-10 V6 had a 31 spline axle I'm pretty sure that there are 2 different carriers because of that.

if u wanna save $$$ get a used one(7.5 posi) from ebay. I found two for nearly $200. 8.8 Rear ends are the way to go but you need $1300 plus installation costs unless u do it yourself. And there are junk yards. In fact im going to call one right now
