I want to replace my front fork suspension on the 09 street glide to a pro action suspension which is supposed to be a better version of HD stock.
Has anyone tried pro action or have a better suggestion?

 

I had the Pro Action's Fork Kit and Street Series shocks on my bikes. No complaints.

 

I just bought a new RG 107 last month and am a huge believer in suspension after having tarted up the front end of my previous bike (2013 Dyna Switchback) with Traxxion/Racetech springs and Gold Valve Emulator. I spent about 2 weeks heavily researching shocks and fork suspension options for the RG. I went back and forth on high end cartridge kits vs a Pro Action type upgraded damper rod system. Ultimately, I went with the Traxxion AR-25 damper rod kit. It is very similar to the Pro Action kit in that the damper rods are better quality and machined with different holes, with the difference being Traxxion includes their version of the Gold Valve setup, which gives cartridge like valving. Like the Pro Action kit, you call them, give them your weight and what not, and they cut a preload spacer and specific spring weight (not sure if PA uses a specific weight spring). It's $499, however, it does come with oil, while the Pro Action kit does not.

Also, if you look at DK Customs front suspension comparison, they gave very high marks as a value option to the Progressive FST cartridge setup, for under $600.
