They certainly would benefit a sidecar, but leading link forks would be even more suitable, possibly cheaper, if you can find someone who makes them or can do so:

 

I don't plan on a permanent use of the hack, so the way I understand it I can not install the leading link forks or raked trees.

 

That's true, in both cases.

 

Thanks for all the great info.

 

I would keep the air setup, even if you change the internals, when it comes time to change fork oil, you'll be glad you did, and it sure won't hurt to have the adjustability of the air spring.

The guys telling you to get rid of the air setup don't have a batwing fairing, especially a pre '96 fairing.

 

on my 89 flhs I removed the air anti dive crap, tapped the caps and plugged them. Installed the white brothers spring kit with the pvc pipe "preloads". Worked well, then installed at least 2 more sets of handlebars... LOL! Good luck! Similar to this...
