i am pretty sure it doesn't come standard cuz i have an 00 SR5 4runner and it doesn't have it.
I doubt you'd need one for what you're talking about doing.

a locking center diff is one type of 4wd system - it "locks" the front wheel in, so they pull full time, just like the rears, as compared to the all wheel drive systems that are gaining popularity (where the rear push all the time, the fronts only kick in when the rears slip/spin).yota4me said:my gf just got an 01 sr5 4runner and it has the center lock button can someone explain why this is good and what it does exactly???
