Is it best to change shocks or are there good kits out for this?

 

You have a lot of options on this one...what I did was I bought some Street Glide shocks which lowered my one inch. I liked that but wasn't as low as I wanted to I also bought the Road 6 lowering kit off ebay and lowered the shocks an additional inch. The bike now sits 2 inches lower than stock and I'm very happy. I run my shocks at about 25-30 PSI and I have only bottomed out in about 1200 miles.

I hope this gets you started in the right direction...

 

I put these on my RK and they did the trick, just checked em after a few thousand miles and the integrity looks as good as it did when I put em on:

I put these on my 2010 RK almost two years ago after I ran them on an 09 UC for a year. Same brand as Tucci's, just a few years older.
