I'm improving my Dyna. I decided to start with suspension. I'm looking for stock size progressive shocks. The question is size. I have seen a lot of internet sites that shows stocks size is 13.5 and some of them shows 13. I've checked the length of the shocks on my bike when its installed and it was around 12.7. So I think the size 13. Did anyone change the shocks on FXDS? What's the original size of shocks?

 

I found the size. It's 13. Waiting for my new shocks

 

Phew, that's a relief! Give as a report when you have them fitted.

 

What did you order. Progressive makes more than one shock. I have used both the 412's and 440's on my bike, but prefer the 440's.

 

I've ordered Progressive 412 to save money for True-Track stabilizer.

 

Quick update. I installed new shocks and it just disappointment. Too soft for Dyna on any preload settings. I've created new thread in Dyna forum https://www.hdforums.com/forum/dyna-...412-issue.html
