Please excuse a complete rookie question. As someone who really only uses his 4wd in inclement weather. I don't go off-road at all really. Why would I want a locking rear differential?

In a regular or open diff you only have one wheel on each axle pushing/pulling, the locker makes both work.

If you get REALLY stuck in mud or snow or traction is very poor. For most people, they will probably never need to use it.

The basic idea is increased traction. A locker rear will put power to both left and right rear wheel when necessary.


On days where you aren't using 4WD you can still benefit from a limited slip rear. Take a rainy day where the roads may be slick but not slippery enough to require 4WD.


Personally I won't have a ride without one. I have it in my F-150, my Jeep, and my 72 Camaro.

If you want both back wheels to work then you get the locking diff

Otherwise it's 1 tire fire

Thanks everyone.

Also, keep in mind that the newer trucks have "one-wheel-spin control" standard, that acts similar to a limited slip differential by using the ABS system. It does a phenomenal job IMO, and works on the front axle too when in 4wd.


In most situations, the non-locking diff with OWSC will perform very well. It certainly impressed me. Didn't get stuck, (or even close) this winter!

2WD = 1WD
2WD with rear lock = 2WD
4WD = 2WD
4WD with rear lock = 3WD

Great explanation but hears a video further detailing.


I enjoy having it. Used it a few times to get unstuck.
