Lots of options out ther ebut 2 of the best have to be Cudney and Dynamo Joe. Both sell kits to really wake that sled up.
Since cudney is already listed here's Joey's site
I installed Dynamo Joes kit on my 05 MXZ 600X. It did everything he claimed,I was totally satisfied,drop in kit,no playing around to get it right. A WINNER!!!!
