About to pull the trigger on a set of these for my 13' FXDB, just wondering what the difference between the 444-4039B and the 444-4021B really is? Besides obviously the 1/2" more travel on the 444-4021B. Is the width of the eye where it bolts on different or something? I want the extra 1/2" of travel, I'm pretty sure they will fit even though they're listed as fitting touring models. I put touring air shocks off a road glide on my sportster just required a few washers lol so I'm sure this will work just curious if anyone knows for sure.

444-4021B




Also the Canadian dollar isn't worth two tiddlywinks of dog sh*t.

 

Pretty sure those 13.5" are actually meant for sportster and not dyna. Different weights. I will tell you I have the standard 13" 444 for the dyna and I really like them so far.

 

Nitros in 350mm are in the same price range. The 320mm are $550 Can or so. Don't know about shipping.

Buddy of mine got sporty progressive shocks for his dyna once by accident and the spring rate was obviously off from a light bike to the heavier dyna. Even on the stiffest setting they sagged way to much, so he head to sell them.....nobody likes anything saggie!

Do it right and get the correct model number for the Dyna.
