50-55mm shocks question

Hi all,

As many will know the Yeti is heading back to Shark for the next phase of tuning, part of which is swopping out the front hubs for the 312mm brake upgrade.

I was planning on using sleeve adapters on my 50mm shocks, allowing them to fit in the new 55mm hubs.

The adapters cost £80 so my question is this.

Apart from the cost of shocks, what else, if anything, would I need to fit 55mm shocks?

Thanks in advance
