How to Identify Sure-Grip And Gear Ratio

How To Identify A Sure Grip (Limited Slip) Differential

A limited slip differential provides better traction than an "open" type differential by automatically transferring power to the wheel that has the best contact with firm ground. Through the years, all of the major car manufacturers had their own names for the limited slip design - most notably General Motors' "Posi-Trac".  The term "Posi" has now become a generic term for limited slip differentials, regardless of the make.  Sure Grip is Chrysler's name for the limited slip differential. It was introduced as an option in 1958 with Chrysler's 8.75" axle assemblies.
