G80 locking rear diff question

[07Lbz_]

Hi all
I have read up about the g80 locking diff in our trucks, and I have seen where it is supposed to to unlock at speeds above ~20 mph. If that is so then why can I hit the skinny pedal at speeds much higher than 20 on a dirt road and look back and see two rooster tails/ spin marks that I left on the ground? Just curious, I do not have any problems with my rear end not coming unlocked when turning etc. just curious? Thanks!

I'm new to these forum and accidently posted this under parts #s and couldn't figure out how to move it.. So I just reported here. Sorry if I should've done something else please let me know

If the load is distributed equally it will spin both tires, whether its locked or not.

Read this thread, it will either answer your question or confuse you even more like it did me. It does have some good information though...

Help on Locker/axles

dodge's limited slip works decent...but still in the same boat as all the others with them wearing out quick
