You actually broke the shock? The shock itself is rebuild able, unless of course you actually broke the mounts or shaft. The stock shock is an ACT gas shock, I rebuilt my original & put it aside & put on a FOX Zero Pro, figuring if I need one I have one to swap out. The original part # is 1704-117 & runs about $250. Sorry I don't have a measurement & I'm not in my garage right now to do so. IMO, better off to replace with OEM or equivalent, a dealer should be able to help you with the right one.-Mezz
