12" being talked about is the length of the shocks.

 

1st of all - you don't combine the low-profile shocks with a lowering kit.. unless you like rubbing your rear tire off... pick one or the other - TJ lowering makes a great lowering kit for the '07s - and it doesn't change the shock angle. A lot of guys here say they don't like the Harley profile lowering shocks cause they give a harsher ride and are not as good for 2 up. That said, a lot of guys will tell you the same thing about using a lowering kit - so you are going to have to read all the stories and make your own call on that one,but I wouldnt go morethan 1". I ended up buying an '08 FLHTC- it seems lower to the ground than the '07s. Another idea, get yourself a pair of Harley boots with thicker soles.. or get an oversize boot and put a pad inside... cheaper than lowering shocks.

IDS... Isolated Drive System is a bolt-on component for the rear wheel pulley that smooths loads to the drive train.

 

right, that's why in my post I said either/or (or that's what I meant anyway) I follow you

I'm leaning toward the lowering kit, not the shocks -

Do I have to lower the front or can I just lower the back?

thanks for the reply on this - I searched the forum for IDS and found I lot of info so I'm on top of this now. I've noticed the chatter in my tranny when I decel to a point in my rpm that I need to down shift. I felt like I had too little load for the gear I was in and dropping a gear loaded it up and got rid of the chatter. I haven't liked though and now that I know what is going on I'm kinda pissed that they don't do this as a recall. They're trying to duck this by calling it an "enhancement" but they're putting it on all the 08's standard. It smells like BS to me...

thanks again
