I have been debating on what type of low profile shocks to go with on my 2010 Ultra Classic. When I looked on ebay there were about 45 different sets of harley low profile shocks.Most of them were new being discounted small amounts with the biggest discount being about 20 percent. Other than a few no name sets I didn't see anything else such as Progressive. I have spoken with Progressive and they recommended the 430's based on my size.I'm just trying to sit a little lower and I already have the stock low seat. I would be interested to hear some opinions between the harley shocks and Progressives. Thanks
