newbie question but what do lockers actualy do? i read alot of stuff on here about them but i never understood what they actualy do.
any info is appreciated.
thanks. (:

 

A normal 4wd system has differentials in the axles so that when you turn a corner, it will differentiate and not drag a tire; it allows the inside tire which is a much smaller circle, to turn at the same speed as the outside tire.

The disadvantage of a differential offroad is if you lift a tire off the ground or if one tire is sitting on ice, the tire with less traction will spin. So in all actuality, a 4wd with open difs, is a 2wd; one front one rear.

By installing a locker, it locks the 2 shafts together, providing traction to each tire equally which makes a huge difference offroad. HTH.

 

A pic (sample video) is worth a thousand words.
