What does "lockup" percentage mean w/ differential

[Jand3rson]

I'm seeing a lot more about differentials with 40%, 60%, etc... lockup, but I'm not really sure what this means.

I know how limited slip works, but only a little bit. Can someone explain how a diff actually works, and what the lockup percentage means?

Thanks. :up:
