I bought a SCAT9000 crank new that is already balanced. I am looking at a set of EAGLE rods that are already balanced. So if this is the case should you still take all of the peices to the machine shop and have them re balanced or just things like the pistons, balancer, fly wheel etc? The machine shop also asks for one complete main and rod bearing as well as one piston with the ring installed. Would one of you clear this up a little for me.

Thanks
