What kind of differential is a Posi track?
What kind of differential is a Posi track? Posi-Track is a shortened generic term for the GM-branded name "Positraction.". It is a type of limited slip differential. To understand how limited slip differentials or LSD works, you must understand how a differential works, and how it relates to torque. In basic terms, a differential takes the power from the output drive... How does a Positraction unit prevent loss of traction? Positraction units prevent loss of traction by sending power to both driven wheels. At the same time, each wheel rotates independently when necessary, preventing the non-slipping wheel from losing power....
