is true track the same the as detroit-locker and traction locker the same as posi?

trying to read up on different types of differential but it appears these are interchangable so its kinda complicated to understand what someone is talking about

From what I've learned, True-trac is the same as trac-loc but with gears that lock instead of clutches, nothing to wear out, only engaging when a tire begins to slip.A detroit locker is locked, except when cornering and it is clanking engaging and dis-engaging. they are all posi, just different manufactuers come up with their own terminanology to be cool.

I'm sure if I'm not 100% correct, someone will set me straight.[>:]

thats how i understand it

I consider anything that drives both wheels a Posi but I keep getting corrected that Posi is a Chevy term. I have always use the term Posi to discribe driving both wheels and I'm too old to change my ways now.

open = one wheel peel
posi/ trac loc - clutch type "limited slip differential" run open but will put power to both sides as one loses traction...but only if clutches are in good condition and set correctly and traction loss is not too violent. Tend to wear clutches quite quickly if you are into tyre frying and/or hard powering out of corners.

true track/ torsen are helical geared - next level up. Run open until traction lost on one side then gears lock in to equalise. But not prone to slipping like the clutch type. Once in, theyre in for good until traction is restored. the helical gears mean no bang like the old style locker.

old style detroit lockers are also open until traction lost. engagement is more violent.

spools/ mini spools drive both wheels equally all the time and are not enjoyable to drive on the street due to the different turning radius between inside and outside wheel.

for any one considering it, the true trac is by far the best I have ever had anything to do with in terms of both driveability and wear. Gunjam has one in his stang and loves it.

Just to insert a subsection into the limited slip (posi and traction lock) section, an Auburn rear uses conical clutches instead of the typical flat clutch packs. This makes for more clutch surface area, better grab, and better control. Those I've talked to with Auburn rears are very happy with them.

That said, I want a TrueTrac

I'm trying to get a true-trac too.

translation...its really easy to control the degree of sidewaysness by using your right foot with minimal steering wheel input.
