The Posi spreads the wheel power for wheel management. On the other hand, if you face bad road condition or a shabby area the limited-slip is ideal for you. Of course, NO! Positraction and limited-slip are both types of automotive differentials. Besides the more power ensures better rotation. General Motors gave a trading name to their Limited Slip differential.

A limited-slip differential (LSD) is a type of differential that allows its two output shafts to rotate at different speeds but limits the maximum difference between the two shafts.. As a result, power regulation gets high. Most Limited-Slips, sometimes called posi’s or positraction diffs, use clutches to drive both tires, but allow the clutches to slip when the vehicle corners and the axles need to turn at different speeds. Posi-traction is just a GM trademark for limitid slip differentials and traction lok is fords. You can see the differential in the rear axle middle, the front axle middle, and sometimes both. In a positraction differential, the unit senses which wheel has the greatest traction, when one tire is slipping or stuck, and sends power to that wheel. I punched it on some gravel and my back right wheel spun for a second and then the left wheel kicked in. … Both are useful with distinctions. So have a look to find the differences. Too easy?
