Just wanted toknow what some of yall are running in the old axle and witch you would prefer.

 

Locker on the street?

That is a little too nutty for me, you might as well scream "POLICE PULL ME OVER NOW!!!". Lockers are a bit finicky, if you try to accelerate around a corner you will find that you will lock up, and screech a tire, with popping and clanking noises as they engage.

I've got a torque biasing diff in the Mustang and in my Dodge.
(detroit true trac)

 

Haha. ok Where did you get yours?

 

How's the True Trac working for you, Bent? I'm seriously considering one for my 8.8 swap in the future.

Personally, I'd rather not have a locker in my daily driver. There are definitely people that do it, but as has been mentioned, they get real finicky in corners, and they don't like slick surfaces at all. Limited slip andtorque-sensing differentials are much easier to drive with. But on a weekend driver/strip car, I'd probably go locker

 

I have not driven the Mustang yet with all of the Moser and Detroit goodies under it.

I have put about 60,000 miles on my diesel Dodge pickup, which has a torque biasing differential. They are great, but they have a weakness... If you have one wheel in a zero traction situation (like lifting it in the air around a corner, or driving on ice), the differential acts just like a conventional. Some companies sell pre loaded torque biasing differentials that still transmit power to the wheel with traction should one wheel have zero traction, but they are big bucks. I think that for a primary street machine they are awesome, especially if you are into autocross. As for drag racing I have no experience, but I can say that with 700+ ft lbs of torque my dodge will launch straight and burn two nice strips if I feel like it.

Compared to a clutch style limited slip I think they are superior in every way, if you did lift a wheel under power with a clutch style limited slip, you would just be frying the crap out of the clutches and transmitting very little power to the ground.


As for where to buy them... I chose to use Moser, they sell a Nodular 3rd member that is 22 pounds, $235.00 and is good for up to 600 hp. You can't beat that unless you have a Ford nodular case sitting around somewhere, and you do want to watch out for some of those monster cases, they are pigs at almost 40 pounds. The only suggestion I have is to call around, I dealt with two different salesmen at Moser, one was a great, one was difficult (I was ordering up custom 31 spline axles with a different diameter boss for the Cobra brakes I'm using).





Moser Engineering (check out their lighweight Nodular 3rd member)

Strange

 

true trac FTW
last I checked the only ford application was for 9" not 8
We use one in a 500hp tarmac rally car that gets seriously punished and its holding together no problems.

 

yep they have them in 8" now I have the tru trac helical gear in my stang.....I love it.

Lockers for my Jeep, LSD's for my street cars.

 

I checked summit, and they have them for the 8 3/4". $425 from memory.

 

Here we go,the True Tracwas $489 not $425, but has to beclose to the bestoption for LSD in the 8"
