The TTXP85 was an OEM shaft only, not available in the aftermarket. The information we have is that it was made in both the .355 and .370. So, it depends on what irons you are installing it in. The r flex is 94 grams and the S is 96 grams, so the TTXP95 would be a close replacement.

Thanks Britt, I am asking as it came in a stock King Cobra Oversize Irons (Regular & Senior flexes). Everything I have found for that build seems to indicate .370 tip for the irons but haven’t been able to confirm.
