Looking at the different choices in differentials.... it sounds like the Detroit lockers will change the handling ability of the car, as well as the spool option, so it sounds like my options are the Detroit trutrack or other posi unit, but how well do the trutrack or other posi units hold up to dragstrip action? I'd like to keep the drag strip action strong while also not losing handling ability... please help me out in this decision.

I didn't notice any handling difference with my 9"/locker......

You'll be fine with a Detroit Tru Trac. Your not even close to the power level it would take to break one. If you put alot of daily driver style street miles on your car you don't want a locker or spool. Those can be driven on the street but like you stated your gonna lose some turning ability & be dragging tires around corners which will decrease your tread life.

TruTrac is great. u wont have any problems

MachoCamacho

cool, also do you have to replace the torquearm with the 9" assembly(looking at buying from driveline solutions right now).

not with his, but Midwest and Moser M9 units you do

^^Correct. But Midwest is working on comming out with a torque arm bracket to work with stock style applications.

And Midwests complete combo isn't much more than a standard posi 9" set-up from anywhere else except its custom fabbed & you get a crossmembers & torque arm with it.

We've seen the Truetracs handle 600 rwhp, that is what I would go with for your application. Bob

I might be turboing in the far future, what kind of power have truetracs seen and held u to regularly?

i know the truetracs will go well into the 9s in a full weight street car. i have assembled and sold many of them with my rearend combos.
