I bought this shock and installed it on my GS it really helped the ride. Sold the bike with the stock shock.
$80 shipped to con-us.
This is a 2009 shock with the bolts to mount it to the GS. It should be plug and play. Its already set up to run in the GS and didn't rub at all for me. More information can be found here:

08+ is the better version of this shock.
