Im sure there are hundreds of threads on this but !!!!! HD has 2 kits profile lower kit and just fork lowering kit!!!!!!
Whats the big difference ??? Who has used these any pros and cons!!
I just bought this Ultra and need to lower it just a it!!!!!

Also looking at the lowering blocks for the rear !!!!!


2006 Ultra Classic

 

most likely the diff will be how much is lowered. as for lowering blocks i would advise againt it. increase the angle of the shock decrease the rebound. with the weight of a u/c rubbing and bottoming of shocks may be an issue

 

Just go with the HD low profile shocks (stock on FLHX). For the front you might want to consider a lowering kit from Progressive which would get you better springs.
