• High pressure gas charged for consistent performance

'09 Dyna FXD. These shocks are awesome. Installation was pretty easy. There are metal inserts that must be pressed into the rubber bushings of the shocks. It's difficult but made easier with an extra pair of hands and a table vice used to do the pressing. Patience, lubricant, persistance. After the shock set up (take your time, and figure out your sag ) the shocks proved to ride like a dream. A universe away from stock... Much better than the air shocks from "baggers" i've ridden. They brethed new life into my Dyna. I spent a 2-up weekend with my awesome girlfriend and the bike was rock solid, never bottomed out, and handled like a racer in the twisties. Over all my bike now feels planted to the road. Tracks straighter and feels more stable. Pricey upgrade but worth every penny. This should have been my first high-dollar upgrade even before "horse-power" improvements.

Product very neatly packaged. Perfect fit on my bike with easy installation; less than 20min. Changed the overall ride of my Dyna tremendously. I would recommend to anyone thinking of changing out there shocks to buy this product, you will not regret it one bit.
