I called JL and about 10 other places and no one makes one for the 660 Grizz. JL makes one for the 600 Grizz, but said it won't work on the 660.

Is there that much of a difference in the front steering of the two, that the 600 dampener won't work on the 660?

 

I'm sure that someone will come out with one if the need is there, eventually. I'd be careful about adding heavier weight to the front end and heavier rubber, it won't help the shock feedback to the bars at all. I'll bet one of the dampeners could be adapted to work, but it might take a little time figuring out how to mount it correctly and some welding and fabrication. I'd be surprised if there is not one out for the '02 Grizz by summer.
