4wd max speed?

My wife drives our Tacoma, I really wish it had 4 wheel auto.
Our Z-71 has auto 4wd and it work great for her and I worry less about her.
We don't get much practice driving in ice, very few icy days in Ft Worth.

 

for what its worth, our 4x4 is not ment to be used on dry payment or high traction conditions. i would check out 4x4abc.com for very useful info in general. i would also get into a gravel or muddy area to check out the difference in gearing between hi and lo range... bc lo range on my truck is like beast mode torque wise but prob wont go 5 mph in first gear.

 

I've hit 100mph in 4wd before. About 5 years ago on a dirt straightaway in the desert, closed course. No I'll side effects whatsoever.
