NOTE: 

Some aftermarket Grom sprocket/cush hubs uses socket head cap screws, which seats perfectly into the recess channel. If you're keeping the OEM sprocket carrier hub and the OEM studs, then OEM 8mm size nuts would sit inside of the of the step, however if you're using a 8mm flanged nut (aftermarket), then you would need a 8mm flat washer. The OEM 10mm and aftermarket 10mm size nut would need a washer, you may use 10mm crush washers (banjo bolt washers works) or similar size washers. Please see product photos for additional information. These washers are NOT included.
