 The articulation test, a Dodge and a Ford 4x4 with 'limited-slip' [also sometimes referred to as posi] differentials are also used to show the difference of the Easton locker in the GM trucks.  A ramp is used on the left [driver's side] so  the right rear tire will start to loose traction.

 The Dodge was up first an lost traction and spun / smoked the right rear tire.

 Then it was the Ford's turn, that truck was even worse.

 Finally the Chevrolet, is would barely slip and then the clunk of the locker locking in and up the ramp it went.

Chevrolet 4x4, all the way up the ramp after the Eaton locker 'locked in', the smoke in image is only exhaust.   I was quite impressed by this demonstration.
