    For as much as you drive it, why not just put a spool in it?

    Well have to discuss this. You did talk me out of not buying that manual rack and that worked out.

    Just ask Lou, he'll tell ya. I'm sure that for the 3 or 4 times a year you actually drive it on the street around West Mifflin you won't have any problems.

    I have a spool in the T/A and drive it on the street all the time. Real hard on tires though

    Has anyone tried Eaton's True Trac? I hear it is a better then the Ford Track Loc, but easier on the street.

    No way I would ever use an eaton in mine, stick cars with slicks will completely shatter one. I personally know 3 people who have done so. The 31 spline Ford unit will out last the Eaton by far.

    I agree, go w/ the 31 spline Ford Trak-Lok w/ the 7/8" crosspin, check ebay, there's usually a bunch on there.

    Sorry to hijack the thread...
    This is for a 400hp street car on 255/40 17 street tires. I was told the Ford TLoc would slip more then the Eaton. Thus the Eaton would give me more (true dual wheel) traction. Any merit to that? Or just go with the alternate Steel / shim / steel / shim configuration in a T-Loc?
    Let me know if I should start a new thead.

    I've installed a few of them, and a factory ford diff is no where near as nice as a true track. They don't have any clutch packs to burn out like a stock piece, and they don't bind up on corners like a Detriot Locker. If you drive it on the street a True Track is the way to go.
