I have an '08, but, I can tell you that having put a Glide Pro stabilizer on, building my own laser alignment setup and getting it all together, my bike is completely different in a GOOD way! The bike always followed any kind of surface imperfection, and steered badly on the interstate...as in, I was constantly fighting keeping it straight.
I had to lean to the right enough that I had to keep my nose lined up with the right edge of the stereo!!!
When I did the alignment the laser lines met at the transmission and were a good inch OFF at the axles!!!!
The stock bushings were twisted (sagged) and HARD!!!! Jake uses progressively stiff Neoprene and it is also softer than the stock the theory is to make the engine mount/suspension (since the engine/trans/swingarm are one unit called the Powertrain) absorb the vibrations of the engine while taking up the slack of the suspension.
I can't say enough about the bike. Along with using Dyna Beads, I can see two miles in my rear view mirrors, ride with no hands over any surface imperfections and the bike trails PERFECTLY!!! If anyone doesn't believe I'm gonna ride with Outlaw in a couple weeks and I'll do a demo with him....I can ride straight as an arrow and do long or shorter curves no hands and the bike stays stable as if it were on rails!
The alignment has a LOT to do with Bagger wobble and tracking, especially in curves. If you think of it, the rear wheel wanting to go it's own way in a corner causes HUGE wobble.....I'm not afraid to let go of the bars in a curve that I used to fear WITH my hands on the bars....it's that much of a difference!
So I definitely echo what others have said, again I've got an '08 and don't know the difference in the bushings, but I can't imagine they are that much different, just a bigger swing arm.
Here's a pic of how far off the Factory "Alignment" was off!
When I did the re-check of everything, (I did it several times because I couldn't believe how well it came out) I actually thought one of my lasers had quit working. I didn't turn them on till I had the bike perfectly leveled and straight, I didn't want to "prejudice my findings"....the lines OVERLAPPED and made it look like one laser had quit!!! This isn't my idea BTW, I made my own version of the set up Jake had in his video.
Also, go to Glide Pro's sight, Jake has some great video to show you how his system works. The reason I went with his, is unlike some kits, this merely upgrades the stock system and isn't an add-on to the swing arm or frame.
