Ok, workin on my Torino's rear end and wondering what kind of traction device to use

Car will be multi-purpose, short highway trips, mostly street driven, some road course, and some 1/4 mile track time.

I'd like to have something that is liveable on the street as that's where the car will be more than any other specific task.

Was looking at a normal Detroit Locker, as well as an EZ locker, and Detroit Truetrac, as well as a Trac-lock from 9+

not sure which would be best for my car, a full locker or a limited slip

so i need some input

thx in advance

Lockers are noisey but very good. Limited slips are quiet, but the clutches wear. I'd go with the limited slip.

You just can't have it all. Each activity you want carries a differnt suspesion.

The True-Trac will be the best for everything but the 1/4. In the 1/4 it will be better than an open diff but not as good as a full locker or heavy preload clutch pack limited slip. I think I would go with the True-Trac.

If you want to spend and have it "ALL" go with one of the several limited slips with electric locking capabilities.

If you have the cash for it, got with a slip with locking capabilities like M&M said. BUT if not, I'd go for a Limited slip since you'll be doing street, and you don't want your tires chirping all the time at corners and wearing unevenly. Another option depending on price again is going for a remote locking diff. Some work with air pressure to lock when needed, others are cable actuated, others electric etc. this would enable you to have pen diff on the road which is fine if you're not doing donoughts (and even then you can always lock it for the moment... and lock it when at the track for the race. I think he best compromise (price vs need) of all is the last one, you use it when you need it only.

I struggled, researched, and struggled to make a decision. I went with an Eaton Limited Slip and have been very satisfied. The modern factory (Eaton) G80 type differentials have a centifugal mechanism that unlocks the differentials beyond a given wheel speed. Not a good thing if you are interested in high performance where traction through the power band is a consideration.

The clutch type limited slips (Eaton, Auburn, etc.) lock tighter as the wheel speed increases. Unless you hard throttle alot around corners (which is hard on clutch type posi-tracs/limited slips) you should have excellent life out of the Eaton or Auburn types. Hard throttle, in a straight line, provides immediate lock-up (no slip or clutch wear).

Of course the mechanical lockup/ratcheting differentials are a consideration. But make a "ratcheting" noise going around corners.

Spools (where the axles are locked continuously) are an option for drag racing or off-road applications only.

I am fully satisfied with my Eaton clutch type posi/limited slip and would highly recommend to anyone running a street/street rod/street-drag setup.

He didn't say but I am guessing that he has a Ford 9". Because it hasn't been used for MANY years not as much of the cool new stuff is made for them.

For example:
The Auburn Gear ECTED can only be had for Ford 8.8" and GM 8.5" axles at the moment.

The Eaton Electric Locker is only available for the GM 9.5" (factory on the H2), 8.5" and Ford 8.8" axles.

The Detroit Electrac only comes in some Dana applications. They don't plan on making one for the GM 8.5" or the ford 8.8" because they are just too weak from the factory and they would have too many of them come back in pieces. The actuator is externally mounted on the diff cover so that rules out the 9" unless they design a new actuator that is internal.

I don't think an ARB air locker has much place in a hot rod but that is just my opinion. I think They do make them for Ford 9" axles (even in 35-spline) but by the time you add in the cost of an air compressor the price is higher than just about any other option.

Bottom line is using a limited slip, ARB, or swapping in a new rear end. Of those choices I would pick the TrueTrac (or the Torsen copy).
