Hi Matey & welcome to the forum.
Any issues with upper frame clearance & ride height & sag?
The shock you've elected to source isn't the same R6 shock most of us have fitted on our thou's.
Those of us that's done this mod yrs ago used an earlier R6 shock with a ramped preload adjuster ring, these were new/plentiful & cheap as loads were on sale on eBay, pulled from new R6's that were destined for the track.
I'd double check shock top - frame clearance if I was you.
The earlier R6 shock needed a tad filling off the top to get frame clearance, we also drilled out the upper bush centre to accept the OEM Fazer1000 upper shock bolt, I assume this was suggested as the Fazer is a heavier bike than the R6 & the upper bolt takes all the bikes arse end weight, also top hat bushes weren't that easy to come by in the correct dimensions here in the UK, so we drilled the top bush & packed it out with stainless washers & used 130mm dog bones if memory is correct.
This gave a slight increase in ride height over the saggy OEM shock & the spring weight was pretty much bang on for most.
If you're happy with upper frame clearance & ride height & sag, then this newer R6 shock swap has paid off & done fairly cheaply.
