posi lockers?

Hey guys i got a 1970 lemans and it has limited slip....and a one tire fire is not my bag... One of my friends was telling me about posi lockers but he didint know much about them. I was wondering it they are as good as they sound or what? Or if they are only for off road aplications like 4 wheeling? well thanks alot guys.

I assume you are talking about a Detroit locker, not to be confused with a spool, they are two different animals. A Detroit locker performes much like a traditional posi, except the spider gears are caused to lock up. A spool is a solid piece connecting the axles, not to be used on a street vehicle.

If your limited slip in you leMans is only pulling with one tire, it needs to be overhauled. Limited slip was GM's term for posi trac. Fords was traction loc.

well there is also an eatons locker that worked in a bit different way than the eatons posi. The eatons locker has been used through the 70's to present day but is not known for durability so I'd stay away from it.

If you're looking for brute strength, the Detroit Locker is almost bullet proof. Some didn't like the earlier models due to the clicking noise in a turn, from either side unlocking to compensate for the turning radius differentials, but they now make a Detroit Soft-Loc which is much quieter. almost all sold now are that design, look for the "SF" in the part #.

Your friend may have been talking about the Lock -Right locker. You can actually install it in your current rear end without removing it from the car. If you do choose to go this route be sure to use the stiffer springs, this will eliminate excessive unlocking and wear.

Be warned, lockers are loud (clicking and banging), I have one in my car presently and have also run them in the past. I don't mind the noise but, some people can't stand it. Lockers also change the way the car handles (for the worse), takes some getting used to. Also have to be careful in the rain as the car will tend to spin out easier if you get on the gas in a turn or U-turn.

The good thing is they don't slip period.

Spools have no place on the street, so avoid that temptation. They are for RACE ONLY applications.

I got a Lock-Right in mine, better than importing an axle or doing a rebuild, had it for years, no trouble.People tend to point out I have a bad rear end when parking.
