Ask and receive... 
The part number for the upgrade of MY 2010/11 Pro Chassis sleds is MY12 2204633, ENGINE MOUNT BOLT ISOLATOR KIT
This kit will include 4 bolts (#12) and the radial rubber inserts (#19 & #21)
This will be able to be installed with the motor in the sled.
This kit is NOT a warranty update for your 2011.
Yes, there have been some broken motor mounts, but this has not been a wholesale problem.
IMO... it is great that we are able to keep our past MY sleds up to date with new MY technology.
I believe that IF you have your sled at the dealership currently for broken motor mount bolts on a 2011, that the dealers will be upgrading to this new kit....But this is speculation on my part.
The street price on the kit is $68 and your dealers should be able to order this now.
