Hey guys. I have a chance to pick one of these up from only 50 bucks.

I want to know more information on these things before I go ahead and but it. I know that I will need a spring or two and maybe to replace the clutches.


Is this a waste of my time? should i stick to going with the Eaton unit like I had planned?

 

There are no clutches or springs in a true-trac. It is like a torsen. It has spiral gears that press against each-other. If it isnt broken in half, it should still work. They are torque proportioning, so it only "posi's" when thee is torque applied.

what does that mean, that it only posi's when torque is applied. isnt torque always applied. sorry im dumb when it comes to this stuff

 

When you are under coast there is no torque applied to the pinion or into the rear, the momentum is keeping it moving. When you are accelerating there is a lot of torque being applied, when you are cruising, very little. The amount of torque you apply to it determines how stiffly it splits the torque.

 

so there are no springs at all? He told me that one or two of them were lost.. I was aware that it locks up like that, so i guess there are no clutches at all..

How strong are these units?

 

It has no clutches at all. Their slogan is something like "no clutches, no cones, no problem" or something like that. I think there are some wave type spring washers in there, but no regular type springs that I know of.

BTW- they are stronger than stock, but not as strong as an Eaton or Detroit Locker. Probably about the same as a Auburn or so. They do make some competition ones that are pretty tough also, but that is circle track, like 9".

 

Thanks for the info... for only 50 bucks, I see nothing really to loose here. Heck its like 8 times cheaper than an Eaton and I won't have to pay shipping on it.

 

Can you feel/hear a locking/unlocking movement with the True-tracs like the Detriot lockers?
