Does anybody know if gauges from a 2009 Ultra Classic will fit on 2006 Ultra Classic? My friend bought new gauges for his 2009 so I'm thinking of putting them on my 2006...I just like the way they look.

 

Just going by what the HD accessory catalog indicates on this....
Speedo changed from 07 to 08 so wouldn't fit your 06
Tach should be okay
Volt meter should be okay
Fuel gauge changed after 07 (larger tank?)
Oil pressure gauge should be okay
Air temp should be okay.
I would suggest that you go into the HD site and compare part numbers for your 06 and your friend's 09 and see what comes out...
Seems like a lot of work for what you would gain but if you are in a "snow" area you have nothing but time for the next few months.
Good luck...
