I noticed some wear on my 2015 TS LT, so started looking at sprockets and they are the keyed kind at 90 a pop add the chain on top of that and it looks like a big chunk of change. So I'm looking at changing over to a splined shafts, has anyone done this and what can I reuse and what need to be converted? I did search the forums and the information is somewhat dated. Is it worth converting? The quote I got for parts is around $600-700, is there a cheaper way of doing this.
