How-much $$$ do you have to-spend?
Performance Suspension has a # of choices to suit your pocketbook. The 412 series is better than OEM and kind to your pocketbook. Their 440 series was the 'premium' choice, but I believe has now been replaced. Probably almost 2X the 412 price.
Morley's Muscle (below) has a great price on these, if you want a quality shock w/o spending $$$, this is what I would recommend.
An OEM-compatible choice, easy on the wallet, cheaper than the dealer's (by far!):

First upgrade:

If you ride two-up a lot, this is probably a good choice, since it's easy to adjust to different loads:

These links aren't the cheapest, I'm giving you a place to start.
There are other shock suppliers. Penske if you want to spend Big Bucks$$$. Our bikes aren't circulating the racetrack, so you don't really need to go overboard here.
If you
do 'like to go-overboard," start here:
