What is the difference between a Tru Trac and a Sure Grip?

I believe the true track is a locker. Not independent

 

[mmirwin]

A Trutrac is not a locker and is still a 'limited slip'. The difference to a factory 'posi' is that the Trutrac has no clutches to wear out. It has helical side gears on ramps to equalise torque. I have one with 3.55 gears in my car.
