I have a chance to get a A-Kit rear shock for 300 dollars from a friend who is a local pro rider. shock has oversized DLC coated shaft and anodized clevis but shock body is stock with factory connection remote reservoir and he says it has A kit internals. either way the shock is worth the 300 with the dlc and remote reservoir. I am away at school and away from my bike and can not measure the 13 shock and see where the difference is. I asked this question and didn't really get the answer I was looking for. As well have done a search for people asking and some people say yes then others say no and have not found a confirmation of it. I know the rear shock on the 13 is shorter by 14 or something MM however is this just the clevis that is different as I can change the clevis by just depressurizing the nitrogen and changing the clevis's out has anyone just swapped the shock and did the longer shock make a difference.
