Uncharged cost

While it is an upcharge shaft, the upcharge will be the same per wedge as per iron - if you already have that shaft in your irons.
Titleist reps won't be posting pricing on this forum for user comments. If you don’t have a current upcharge for irons, your best bet is asking an authorized dealer for a quote.

I went into clubs on this site and built a SM10 wedge with that shaft is available with two options. Here are my findings. One has an upcharge and the other does not.

Nippon NS Pro 880 AMC Upcharge of $25 per club, when ordering new thru Titleist, but if you order the Nippon NS Pro 880 AMC Chrome there is no upcharge in a new SM10. Hope this helps.
