All big trucks are still using straight axles up front and cruise all day at 70-80 so thats no big deal. I TRY to stay at 65 in mine but all of a sudden you look down and its like silk at 70+ and climbing and i just slow it down to stay safe in my own mind because im not in a hurry in that truck but i can drive it with my knee at 70mph all day. Good tires, correct toe and the right gears and it will just float along.
