I have owned my last 2 wheel drive pickup

He has a Ford F-150, not a GM. It won't have a g80 locker

I was referring to scardychicken's Chevy Silverado. Maybe he was talking about his Mazda project truck? Anyhow, sorry for any confusion.

I am under the impression that the G80 option differential will lock anytime one of the axle speeds exceeds the other by 120rpm. It has no way to determine actual MPH.

I was also, until I started reading up on them. Members of several off road sites have mentioned it in the course of various discussions.

Yes. I read some of that as well. Generally, it looks like they like the auto-locking hubs for most situations. But there are some where you'd like to lock the hub manually BEFORE going into a situation, or have it stay locked in DURING a situation. GM's auto-locker won't do that. It'll only engage if you start spinning one rear tire 120rpm faster than the other and disengages by itself.

On the plus side, you can't forget to turn it off.

10 years ago, Ford had the best hub set up automatic with manual over ride, just in case. My last Ford was an 08, I dont know what they have now.

I believe the biggest reason they kick out at 20mph is do that if one tire breaks loose at higher speeds, the other won't take over and send you around in a circle. Kind if like that SUV you posted a couple of days ago.

I went from
89 Dodge w150 4wd 15years 243k short bed best truck I ever had.
2004 Tundra double cab 4wd beutiful smoother than a caddie but way too thirsty, the only truck I ever traded at 37k
2007 Tacoma access cab 2wd, nervous in winter?? put Nokian Hakkapeliitta Tires and 290#s of steel plate in bed. No slipping at stop signs, no anti lock brake activation, I can take ramps at 45mph during snow storms. Now if I go off the road i will not be able to come back through a snow bank with 2wd but I find with these tires and the low stance of my truck, the stability is amazing. I ended up puting these on the wifes minivan and the son's Corolla. It's like night and day. BUT with out the wieght and tires I go nowhere in the snow.
2015 Tacoma Access cab same setup

These tires will improve your vans traction 75% with some wieght added. The winter compound goes all the way thru the thread unlike some other brands that only have the winter compound half way down and then the ALL SEASON compound starts. This does make a difference. I do not work for the company but I have been happy with every set I have purchased. You cannot run these in warm weather though, winter use only for the ones I buy.

We have Hakkas on the Sprinter van.

And 4Runner.

And Prius V.

I would be comfortable with any of those tread patterns.

Looks like a modern version of the old directional tread snow tires I ran in the 80’s

I've actually been reading up on the G80 quite a bit, as I would like to stop running my Colorado full time and make it more of an offroad truck for when I need it. Tonight instead of shifting into 4WD on the icy hill before my house I shut off the TC, to see if it would make the hill with just the rear differential locked. I made it about 2/3 of the way up the hill before the truck stopped. Shifting into 4WD I was able to go from a dead stop and continue up the hill. Had I been able to manually lock the rears it may have been different, as I would have been going faster than 20MPH while going up the hill.

Could be. I just can't find any literature that says they kick out at 20.
