alright, i got a stock GM posi in my car, and its worn to sh*t.
instead of fixing that, what would be a better option?

ive heard of people talk about detroit lockers, but how do those work? when one tires slip, it locks up? or is it permanenly locked, so when i take a corner the outside tire drags?

 

Iassuming you have a factory 7.5" 10-bolt, I'd stay away from a locker for a driven street car. They're much more aggressive than a posi, thus are harder on tires and axles. A decent posi will work just fine for some pretty serious use.

 

A locker has great big giant teeth that mesh together. When you turn, the teeth ratchet against each other and make a loud clicking noise. They are generally overkill unless you have an excessive amount of power(and if that's the case, you'll need a bigger rear end anyway)

You're thinking of a spool which permently locks the axles together and makes cornering "interesting"

 

From what I have read , the Detroit " soft " locker use`s preloaded springs that cut down on the traditional noise that is normally associated with the original Detroit locker. I like the idea of the soft locker because it allows both rear weals to work evenly even at lower torque levels . It still allows turns with original freedom. Its a little more expensive , but I like the idea of both wheels locked . I love the sounds and feel of a modified car.
Slowly mine will become the" Pony Car" with the power and rear wheel torque I love.

I agree with Shagwell and Coach Hawk. Just get a good posi, such as an Eaton or Auburn Pro. My preference would be the Eaton, since it's fully rebuildable, unlike the Auburns. I ran a locker for quite a few years on the street, and I hated it. The "cool factor" of it being noisy wears thin really quick, trust me. I have a gear drive timing set in my 69 Camaro, and I don't mind that noise at all, but a locker just makes your car sound like a POS when you turn sharp around a corner.

 

detroit true trac LSD FTW!!!!

 

i've got a powertrax locker in my 10 bolt. it bangs and rachets and people always ask "what the hell was that noise?" but it doesen't bother me because i know it's always going to spin both tires.

 

no it wont, when you are turning, and its unlocked, stomp on it. if i do it i will obliterate 1 tire.

 

With further research done , talking directly with what I consider extremely knowledgable and experienced people concerning this subject ,I will be going with the Eaton Posi .for my application .

 

Just an FYI those powertrax lockers are garbage after awhile. i installed one in my old K-5 Jimmy i had, and after a few months when i made a turn it would bang and jerk around as it tried to unlock but didn't...almost made me crash a few times. shortly after it started doing that it blew up and completly obliterated the teeth inside, and only spun one tire if it even moved at all. i tried calling powertrax but they told me i must have installed it wrong, and they wouldn't cover it. even though i followed the instructions. just my

 

I bought one of those powertrax lockers as well and it wouldn't even lock up. I called powertrax as well and they said I had too much clearance, so I checked the specs and I had less...you made a good choice with the Eaton.

 

the one in my car has been abused for 3 years in 2 different cars. i'm really not too worried about it's durability. i wouldn't go calling it garbage just 'cause you had a bad expirience.

 

i wouldnt call it god just because you have had good experience

 

neither did i.

 

On the powertrax/qwick lock and tracklock type carrier replacements: these are recent additions to the market for an "inbetween" locker, one that is not as hefty and loud as, say, a traditional detroit, but does not wear or slp as easily in severe conditions as an LSD. From what I have seen, if it does not sound like a locker, function like a locker, or drive like a true locker, its not going to hold up like one. Detroits are awsome for what their intended use is: off-road or severe road conditions that would cause the clutches in an LSD to give out too soon. For a street machine, at least mine anyways, I doubt Im goin muddin any time soon, so an LSD will work fine. My personal rule is that if it reuses the original carrier, its not worth the time or effort.
