You have made some good points and I agree with most of them. You should not plan to go much over 8mph in 4low, it just isn't made for that. Plus if you actually get it to upshift, that upshift is going to throw you for a surprise. Stay below 8mph and you'll be fine.

What I don't agree w/ is your limit of 50mph or lower in 4Hi. This 4Hi system is meant to be able to cruise normal highway speeds at. In fact, the V8 4runner is in fulltime 4hi with all the same components (less the locker in rear of course). When I drive up to Mammoth and it gets a bit icy, I'll switch 4Hi on just in case, but I'll still go well over 55mph. It's not dangerous if you know what you are doing. What is dangerous is following too close, not slowing down for a turn, and expecting that you can stop on a dime.

Even offroad, I go over 55mph on occasion. I have buddies with long travel setups that go upwards of 70mph in dirt and I try to keep up (not ever going much over 60) and I do fine.

So yeah, I completely agree w/ you on the 4Lo, but not really on the 4Hi. I think the majority of 4Hi should be slower than 50-55mph (obviously when really offroad), but it won't kill your vehicle to go faster.

The way you put it I completely agree.
