Just preparing for that myself on an 08 Fat Boy.
All primary gaskets, inner & outer. Use a little silicon on the inner primary gasket/seal to the case.
Seals for the starter. Be careful on installation not to damage.
O-ring.
Replacement bolts for the inner to the case.
Very large impact sockets. not sure if you need a pulley.
My starter removal requires long 1/4" allens, a ball type will be helpful.
On mine the shocks do not have to be removed, as the fork will allow enough room after pivot pin removal.
A bro to help!
good luck
