There is no set in stone "MAX" speed really. Just good common sense. Most owners manuals will tell you 55 mph but I drive 65 mph on a regular basis and have had no problems. I might mention that is when on snow, gravel or dirt roads when conditions allow for those speeds. The only thing I have noticed in the past is a slightly higher temp reading from my tranny temp gauge (aftermarket and fairly inexpensive) along with a slight whinning noise the faster I go. In 4 Lo you have to be a bit more careful. Hope this answers your question.

By the way, regarding this subject (high speed driving in 4 Hi for great distances), much of my experience comes from renting Blazers and driving the crap out of them in the mountains in Montana and Wyoming. Have to thoroughly test my future rides you know
