DIRTY AIR "FAST-UP" Rear Air Suspension System

DIRTY AIR Complete *FAST-UP* rear kit.  Redesigned for optimum performance, reliability and ease of install.  This new system includes a larger tank with built-in manifold, along with larger compressor and also includes a safety valve.  System also includes a stainless steel braided airline to connect the compressor to the tank, making an ultra-durable, extremely easy connection.  Valving built into the tank cuts down on installation time and leak points.  Plus, the larger tank gives you more lifts and allows for easy expansion to front air in the future.

Options to fit Harley touring models 2023-down.  This is a complete system assembled to easily replace your stock touring shocks with height-adjustable air shocks that can lift instantly.  This system will allow you to lower your bike 2 to 3 inches with all of the air released, and air it up to stock ride height for a smooth ride in about 1 second.  DIRTY AIR shocks offer amazing ride quality and performance, with ultra-durable air bag and push-to-connect fittings for easy installation and great seal.  There is a wide range of comfortable travel in the shocks, so you can ride at stock height, or ride lower and still maintain a smooth ride.  Shocks are also capable of extending slightly beyond stock height, if you're looking for extra ground clearance for stretched bags and fenders.  DIRTY AIR shocks are designed and built specifically for Harley touring models, they are not a universal shock modified to fit your bike.

This system also includes our exclusive black standard air compressor which is compact, powerful and very reliable.  This newer, larger compressor is perfectly suited to fill the tank in this system very efficiently.  This is the same compressor used in our fast front+rear systems, built to perform well while standing the test of time on your motorcycle.

Custom built stainless steel tank to resist corrosion that includes mounting brackets to mount on the fender strut/saddlebag/fender support between the rear fender and saddlebag.  2-valve manifold included, attached and pre-plumbed to the tank along with our stainless steel pressure switch for super easy installation.  Tank mounts to the right side fender/saddlebag support, and compressor mounts to the left side fender/saddlebag support.  System also includes compressor brackets to mount securely on the opposite side of the tank.  Stainless steel leader hose connecting the compressor to the tank for extreme durability behind your tire.
