To be honest with you Greencat I am not sure if it is a 162 or 163. I had it on my 09 XP and it was a 163 and it fit just fine. I am sure I knew the size at one time. I think it is a 162" which is what I stated in the text of the ad. I couldn't change the size in the title though as I didn't have that option. But it wouldn't be a 2.82 pitch. Have to be a 2.86" pitch.
