The nut is the same whether you use an 11 or a 12.

When you run the 11 you remove the o-ring and switch to a smaller outer washer.  You can put a dab of grease on the bushing but they will always be a little noisier than the 12.

Also, avoid cheap aftermarkets, never had a failure with OEM sprockets.
