As I understand it GM is the only company that offers a locking differential instead of a limited slip differential in 2 wheel drive models and that a locking differential is superior to a limited slip differential for traction. I'm interested in owners experience with locking differentials since off road traction is paramount to me. I understand that a locking differential can create noise & increased tire wear & am willing to live with that just as long as the locking differential is reliable and indeed provides improved traction. So I'm interested in owners experiences.

A confusing term because nothing on these differentials is LOCKING. They are by far inferior to a differential that is truly (manually or automatically) lockable. If you have to decide whether to get a "locking differential" (LS) if available as an option on your new truck I would recommend getting it, because it is still better than not having anything at all. To repeat: "locking differentials" are limited slip differentials that are not to be confused with differential lock! Differential lock = differential locker = diff lock = diff locker = locker It seems to me, that manufacturers and dealers prefer to use the term "locking differential" over the correct term "limited slip differential" because it sounds more like the real thing - even though it is not. Is this already consumer fraud? Now here is a twist to the locking differential story: When Chevy advertises its trucks with an optional rear locking differential - it indeed is a differential that locks up (automatically). In the 80's it was sold as a Gov-Lok for a while named Command-Traxx and is available in some Chevy trucks as G80 option. It is not manually activated as in Dodge, Jeep and Mercedes - it locks up automatically. It is a hybrid of a clutch type limited slip unit combined with a flyweight governor that is able to lock up 100%. This makes me very interested in buying a Colorado or Canyon with the G80 option locking differential, interested in owners experiences. |

I have a 07 colorado,4x4,z-71 with the eaton g-80 locker.It works as advertised,and does it very quietly and smoothly.It got a good workout this past winter in several feet of fresh snow (with stock a/t's)with no problems.During this summer,we have been off road with it,and have yet to use 4 wheel drive,because of the locker.It is far superior to anything I have owned to date,and I'm an old fart.

Replying to: lvrob (Jul 21, 2007 1:47 pm) It handles much berrer on wet roads. Actually, I don't think the rear was ever right since I bought it new BTW, GM is not calling this a recall, they only have recalls for safty issues!
