AirFX Rear Air Ride mono shock for 2010-2015 Victory Bagger applications AirFX Victory air ride kits are specifically designed to fit all mono shock rear suspensions. Now you can fine tune your suspension for extreme cornering and braking and quickly adjust back to a comfortable cruising mode. Experience fast responsive, grip and true performance all in a package not any larger than your stock shock. The air in the shock reacts much faster than a standard hydraulic shock. By lowering your bike you will change the center of gravity and your geometry. This greatly increases handling performance. Each shock has two air chambers for lift and 1 for rebound in axial alignment. Rebound is set by adding air to the remote mounted Schrader valve, allowing the rider to adjust the rebound settings. Ride height can be adjusted while riding.
