which differential?
I was wondering which is "better" the Tru Track or the Locker, or is it personal pref? If you say this or that is better please state why. BTW I am going to be running 370, and a turbo set up. Hopeing to get 650+ rwhp. Thanks
Edit: if you vote please state why you chose one.

The lockers can be harsh on the street. You have to re-learn how to drive the car. If the roads are wet, hang on Tru-trac's have been proven to live past 1000 rwhp & rwtq ! Can't go wrong with one. I'm getting ready to swap one into my rear soon.

I own both for a Ford Nine inch
The locker is not too street friendly , but liveable. It is loud, obnoxious, clanks and bangs when negotiating tight turns. I used it for slalom and roadcourse events and it worked reasonbly well. It got rid of the dreaded inside wheel spin when applying power in turns but .
I just recently bought the Trutrac(race version) and first time at the roadcourse I knocked 3 seconds off my time . Due to the fact I was not understeering as bad when compared with the locker.

I am looking more for drag racing results but thanks for your input, I really don't mind all the poping and clanking etc. but I have heard or people breaking the tru tracks withnot so much power. I guess I just need more opinions. Thanks so far guys.

Well if your drag racing you can not beat a SPOOL. Guarenteed lock-up ALWAYS.
I Like the traditional Eaton units. You can tune them from street to strip to all out race. Carbon clutches to composite to steel. They have had the cases and spider gears redesigned and tweeked to a great LSD unit over the years for super strength and have been proven in the Chevy muscle cars for years and available for tons of aftermarket applications. They can be rebuilt over and over ...Just my opinion. You still must make the decision. If you are all out race and no street SPOOL IT!

auto or 6spd?
the locker stays locked until you try to make a turn. the true-trac stays unlocked until you apply a load to it, then it tightens up, effectively "locking up".
if you've got an auto, it wouldn't really matter, probably the true-trac for it's street prowess.
I had a true-trac in the 9" I just sold, it always seemed to stay locked up after a few good beatings with slicks and a clutch drop.. would stay that way for a day or so after going to the track. I was always affraid the shock on the driveline and it's design as a limited-slip would eventually break over time.
now, the locker? it's locked until you take corners, meaning it's basically like a spool in a straight line, and that's what I'd put in a 6spd car. they are built stronger by design, than the true-trac is.
I've had both (true-trac in the car, locker in the truck) they are 2 differentials meant for 2 different things.

I've had too many lockers in customer's cars make it feel like the rear-end was put in there without any bolts. It is a strange feeling that many people cannot tolerate. If it is a weekend car making big power, I'd go with a spool. Bob

it has an auto, I can deal with all the noise/ jeaking and poping. From what I have seen the locker would be better. I just don't feel like dealing with a spool right now, maybe I will put one in later down the road.

Here is my take, maybe it helps maybe not.
I have a spool in my 12 bolt. I drive it mostly on the street but its just a weekend warrior. I still had 275 50 15 Nittos on my wheels when I finally got the car on the ground after the 12 bolt install. I could barely stand driving it around my hood. I was like wow this does suck more than I remembered.
Now I switched to a 275 60 15 MT DR and it made a world of difference with the spool. Hardly notice it now.
Just an FYI, a big soft tire really tames the spool.
