Nah, I never bought the aluminum pulleys. I just replaced the plastic ones. It worth looking at the clearance though.
So the center diff works pretty well with the pro 4? I'm interested in picking one up I'm just concerned it would slip and I'd end up squaring off the ball bearings. Other than that it seems like a great idea.
