Its designed to run trucks that have massive lifts. Like was said earlier Trucks Gone Wild. My cousin is working the bugs out of his now. Except instead of the blank yolk on top, I usually see a output brake there. It does work, I mean there is no other way to build these trucks to have a decent driveline angle than what you see. Except lowering the t-case, and as we deal with on ours, thats not ideal either.
Its ingenuity at its finest if you ask me. Come up on a problem and solve it best way you can figure. These trucks arnt designed to do anything else but what you see in his picture. Just like ours, not the best tool for any certain job, but a great thing to watch. Only way you can not atleast appreciate TGW is to have never seen it in person. Do I think they are an intelligent way to spend your money, not exactly, but they are neat, and they have alot of thought and time in them, just like ours.
EDIT. I also think they lose the ability to shift the t-case between LOW and HIGH as well. Its stuck in LOW if I remember right.
