What is the stock c-c dimension of shock bolts on a 2015? It's approximately 300mm on a 2018. If it's 300mm on a 2015 I would think a 285mm replacement would not work.

Replacement shocks are designed to fit into the same dimension as the OEM part. If your replacement shock doesn't fit it's not correctly designed for your bike. Less than one inch is a huge difference. It will alter many aspects of the bike (ride height, head angle, trail, etc.). Any change to these aspects can significantly alter the performance. Plus, the performance of the aftermarket shock will probably be compromised since it will be placed in a longer mount (300mm) vs. it's actual length (285mm).
