Dirty Works Dirty Air "FAST-UP" Rear Air Suspension System Touring

   This *FAST-UP* system will lift the rear of the bike in about 1 second, instead of the 12-15 seconds that most tankless systems takes to lift.  Our NEW basic (tankless) rear system with larger compressor in 2020 lifts in around 10 seconds.

   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.

• For all Harley touring models.
• Allows 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 are designed and built specifically for Harley touring models, they are not a universal shock modified to fit your bike.
• 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. 
  
• Lift+dump 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.

*'14-Later Models with Boom Audio that includes stereo components inside the saddlebags will have fitment/clearance issues with saddlebag-mounted wire connectors, requiring re-routing of audio wires and connectors

*2009-2013 models with "classic" 4-hole tab welded to saddlebag support for saddlebag guards or fender filler panels will not fit the tank or compressor without cutting the 4-hole tab off the saddlebag support or replacing with a standard saddlebag support.

*2014-2016 HD Touring models use the factory fork springs.  New springs are not required or included for those years unless requested due to replacing aftermarket lowering springs.

*On some models, antenna relocation or antenna bracket modification may be necessary.  

*Fender support mounted tank/compressor will not fit with 2014-up rear fender strut filler lights or filler panels

*Please note, with front+rear air, the frame of the bike will sit low enough that the stock kickstand (or even a lowered kickstand) will not allow the bike to lean over far enough to rest securely.  An electric center stand is highy recommended for bikes with front+rear air

*Optional handlebar grip switch will not fit 2015-up Road Glide models due to anti-rotation pin/hole in stock handlebars.  Aftermarket bars work as long as they are not 2015-up Road Glide specific.

*Front parts will not work on inverted front ends like new 2023 CVO models

*MRI electric center stand will not fit with bikes that have a cross-under exhaust pipe - that pipe will not allow the legs to fold up for riding.
