On to a dyna wide glide 2010 up yes !
Done it to mine !
Bolts straight on no adjustments needed, got the hub from HD wheels in the states

the hub was made for the FXDF for blokes who wanted to put

spoke rims on the Fat Bobs

If doing it go a wider rim and tyre aswell the original

Wideglide tyre does not put enough meat on the road for

the extra stopping power

you will also need the fatbob master cylinder !

 

 

Im only talking about the wide glide, it was reintroduced
to the line up in 2010 with 49mm fork tubes. I was not
sure what model OP was really talking about !

The FWDF and the FXDWG 2010 up you could say, have
the same front ends, except for the twin disk on the FXDF,
All front end parts are interchangable between the 2 models,
But im not sure if the tube length are the same, and the
Degrees of the trees. But i think the Wide glide has more
Degrees in the trees !

As for the other FXD models i dont know !

If i was to do it again aiming for the same outcome, i would
buy FXDF, put the wide glide trees and tubes on it, if they are
different, and a 21inch front wheel, think you would save a
few bucks that way, plus get the fatter look of the FXDF tank
and the FXDF rear fender, but thats personal choice !

I have a 120/90-21 metz on a 3.5 rim, handles and rides
100% better than the original front wide glide tyre !
