Suzuki Grand Vitara Progressive Lock (Rear)

 This is a progressive locker for the rear differential of your Suzuki Grand Vitara that provides critical locking action when you need it.

 

Under normal driving conditions, the locker operates as a standard open differential. The locker engages when one wheel is spinning freely, diverting all power to the opposite wheel under load and gives you the traction you need to get over the obstacle.
