I am looking to replace both pulleys on my D/A 7800 RD. I was looking at the KCNC aluminum ones (http://www.kcnc.com.tw/Web/NewWeb/rdjckey.htm).
Can someone tell me if the upper and lower wheel are interchangeable? Should the pulleys carry separate part number's or one pulley fits both?

Same pully both locations. The upper pully is installed with no or thinner washers so as to float back and forth just a little.

While this provides some bling, you may find no improvement in performance at all for the money they cost.

aluminum pulleys are loud.

I have almost 20,000 miles on the stock ones so there must be some wear on them. Figure a little bling while I do the spring maintenance would be nice..
