  • DIRTY AIR rear air system for Dyna models.  Designed for optimum performance, reliability and ease of install.
  • Fits Dyna models 2017-down.  Includes DIRTY AIR aluminum air shocks, standard finish is black.  Standard collapsed height 9.5", extended height 12".
  • This is a complete system assembled to replace your stock shocks with height-adjustable air shocks.  This system will allow you to lower your bike approximately 2.5 inches with all of the air released, and air it up to stock ride height for a smooth ride in a matter of seconds. 
  • System includes exclusive black air compressor, with basic bracket to install compressor in the saddlebag on switchback models, other models will require some fabrication to mount compressor.  
  • System uses all nickel-plated brass high-flow high-pressure push-to-connect fittings throughout the entire system, and a manifold-style dump valve block for optimum performance.  This system includes all of the components for a fully functional, fully height adjustable rear air suspension.  
  • With this system, you can ride with zero air pressure without rubbing. That means you can cruise around with your bike SLAMMED, or also if you ever lost air pressure for any reason you can still ride without rubbing your tire against your fender. 
  • For Dyna models fabrication will be necessary to mount the air compressor and switch.  Kit comes similar as pictured, some parts may vary.  
  • Shocks are 12" extended, 9.5" collapsed.  Switch is a mini toggle switch that mounts in a 1/4" hole, and includes a protective waterproof boot. 
  • Please note - Currently we do not offer any Dyna frame specific mounts for the tank or compressor, so fabrication may be necessary.
