There are many types of differentials. Depending on the type of vehicle you drive and in what situations you use your car or truck in will determine the best solution for you. This article details the different types of differentials and how they work.

 

 

Positractions & Limited Slips:

Posi's and limited slip's transmit equal torque to both wheels when driving straight. However, when one wheel spins due to loss of traction, a patch of ice, mud, too much throttle, etc., the unit automatically provides more torque to the wheel that has traction. Recommended for daily driving, works well in ice, rain, mud and snow. However, in situations where absolute lockup is needed, a limited slip is not the best choice due to the fact that limited slips do slip in some situations.

Positraction is a type of limited slip. The name "positraction" was used by General Motors for their limited slip differential and the name has been associated with limited slips for many years.
