“Posi” is a type of differential that enables its two output shafts to rotate at different speeds while restricting the maximum difference between them. So, what is Positraction and why does it matter? They are essentially one and the same, and it’s often referred to simply as “posi” that allows both driving wheels to spin at the same speed all of the time. To this day, the majority of American cars equipped with a limited-slip differential are routinely referred to as Positraction, or Posi for short.
