I am not aware of any, blowjett on here is a Ohlins guru with access to lots of parts, at one point I was going to see if he could build me some ohlins. The G force though work great after my revalve with hygear. If your breaking bolts and parts it has to be something in the valving. People that ride with me know I pound the heck out of my ZX2 and I have yet to have a structural failure of any sort. That said I went through a revalve once and they were to soft and I could bottom out at will so I rode it like a baby the rest of the trip to keep from destroying it. If you bottom at all I would ride less hard until you can get them serviced. If your breaking grade 8 bolts in shear then its obvious you need to stiffen those shocks. My original valve set up when new from ADB lasted I think 3 years before they wore out and I needed service, again when I noticed it was it started to bottom out with no change, I had to ride like a baby again until I got it home. I weigh 230lbs and in a full body Apex and Hygear has a great valve package for me that has worked, if you send it to them I can PM my details so they can look up my valving. Good luck!
