You can send it Works have them do a heart transplant. I cant remember the exact cost. I had it done about 6-7 years ago. And i think the base price was $180? Just a guess.
I know it can cost more depending on the shape of your shock and maybe an option or 2.
I did it with my 500 rear shock. Pretty happy with it.
Heart transplant is basically where they put all their internals into your stock shock.
