I have just got done looking for about three hours at as many posts as I can and I still have a few questions about this swap that I hope I can get help with.

1) If I use the following parts posted by Bosken; then I believe it works for up to 07, however 08 and later is a 25 mm axle, so I do not believe this will work on a 2010. Am I mistaken?

2) All the parts that are listed here, upon further review, are listed as 06-07. Is this another problem for a 2010 or should the trees be the same from 06 to current and it is just that no one has updated years of applicability?

Thank you for all your help on this matter. I have seen multiple Dynas do the conversion, and only 1 2009 SB, however I am still reserved about the axle size.

 

I see the post on here dealing with Fat Bob trees and he was informed 1" or 25 mm axle, does it really not matter if the 25 mm is not used or why would this be advised?

 

As long as the wheel bearings are the same size as the axle it will work. Both 1" and 25mm axles fit all 2006up Dyna lower sliders. There is only a .39mm difference in diameter.

 

ok, that makes sense. just wasn't sure about reusing the bearing as well, it seems that maybe I didn't pick up on that detail.

So WG trees, axle and wheel. Thanks for the help Kev-O

 

There is one detail missing, the left lower fork slider is different on wide glides. The brake caliper mounts on the lower slider position the brake caliper further inside the wheel. So you will need to change the left lower slider or use spacers. The right slider is the same but the left slider that you need is part 46619-06.

Check out this thread, fatbob trees and wide glide are the same width so changing to FB or WG trees require the same parts, there is some more detailed info on one way to space the brake. Member WS6 used spacers on the disk and caliper but you could just add spacers between the slider and caliper. You could just use washers from the hardware store.
