Its the same riser as used on the Mtncats and the older ZRs. I know pawermadd makes just a regular bolt on riser block that goes between the post and clamps. Personally I picked up a Adjust a Rise riser from Ready to Ride at haydays. It goes from 2-4" over stock if I remeber right. I have it set in the middle and sitting on my sled it feels pretty good but I like my bars pretty high so I would say 2" would be pretty good height.
