You should call them and discuss what you are doing, get them to give you the answer.

 

Your best bet is 11" Progressive 412's, i've had Burly's on and one time it rubbed, just one time but it was enough, i'm 225

 

Dude,
I have 2 sets of dyna shocks; new stock set and progressive 12" chrome full covered 412-4046C. Shoot me a line pls mcjaxinc@gmail.com

 

Thanks for all the good information, I think I am gonna go with the Progressive 440 11.5" --gotta have them in black, but thanks for the heads up on the ones you have for sale.

Possibly the 11" --the guy at progressive told me you only start with 3" of travel in your stock shocks--so you don't want to drop it much. If I go with the 11" shocks--that leaves me with 2" of travel--thats not much.
