I was looking at some threads on this and noticed some discussion about needing to change the spring rate with the Pro Circuit linkage (go stiffer), but that was all in regards to the 2016 and newer bikes. Would that also apply to my 2013 bike? I couldn't find anything that would answer that question.

Usually when the link is longer, it requires a stiffer spring. Regardless of bike brand or year. More leverage....

The previous 2016 KTM links shouldn't require a stiffer spring. The 2016+ KTM PC linkage uses a different knuckle and link arm, and requires a stiffer spring.
I have a Ride Engineering link for the older one if interested. And an Ohlins shock. Both are good upgrades.
