Please I need Ford 9" help!!!

[Pasquale]

I am making a high performance street 69 Camaro and I do not understand all the different options, such as ARB and True Trac, for a Ford 9". What would be the best for my situation if I'm running 1000 hp?

A Detroit Locker with 35 spline axles will hang on to that kind of power.

Is there another option that doesn't lock both wheels together, but can withstand high horsepower? Is this what most people use on high performance street cars?

This is the way to go.

A ARB is a air locker , used on off road rock crawlers . it will not take 1000 hp . I had them in my last crawler with a ls1 supercharged , broke the ARB .
I also agree a 35 spline with a detroit . A tru trac posi will work good But you probally will power thru it .

What kind of rear tires are you going to run? If you not going to put anything sticky out back you can run a Tru-Trac with 31 spline. But if you planning to put a Drag radial or stickier I agree with the boys above.

Is there another option that doesn't lock both wheels together? Perhaps I'm misunderstanding your comment, but the Locker doesn't lock the wheels together (like a spool would). A Locker has an internal ratcheting mechanism to allow the wheels to rotate at different speeds during turns.

That's what I put into my car.

Oh I did not know that. So when I make turns it will disengage and let the rear tires rotate individually? But then when I pick up speeds it will engage locking the wheels together?

Some people find the engage/disengage a little harsh, because Lockers make some noise when that happens, especially at slow speeds like parking, making a U-turn, or backing out of a driveway. But in ordinary driving it isn't noticeable, and they work great for road racing and autoX.

And at 1000 hp, it's really the only game in town that will give you a true differential and the strength/durability you'll need.

Right on, that helped narrow down on some of my rear end questions. And I don't know if you could help me, but I am going to run 295 tires and was curious if most people that run wider tires under mini tubs have to shorten their housing length. Or do they just get offset wheels?
