*New* Dirty Air Rear Air Suspension System Fast-Up

NEW FOR 2020, NOW AVAILABLE! THIS SYSTEM REPLACES THE OLDER VERSION.  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.  

DIRTY AIR Complete *FAST-UP* rear kit.  Redesigned for optimum performance, reliability and ease of install.

This *FAST-UP* system will lift the rear of the bike in about 1 second, instead of the 12-15 seconds that a tankless system takes to lift.

For all Harley touring models 2020-down.  This is a complete system assembled to replace your stock touring shocks with height-adjustable air shocks.  This kit 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.  Shocks are also capable of extending slightly beyond stock height, if you're looking for extra ground clearance for stretched bags and fenders.  Kit includes exclusive black air compressor, new custom shocks with push-to-connect fittings for easy installation and great seal.  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 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.  Call or email us with fitment questions, we try to offer a bolt-on solution for all components on all models, but sometimes there is just not enough room.  '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.   On some models, antenna relocation or antenna bracket modification may be necessary.  2009-2013 models with "classic" 4-hole tab welded to saddlebag support for saddlebag guards or fender filler panels will not fit without cutting the 4-hole tab off the saddlebag support.  Also left side compressor bracket will not fit 2009-2013 cvo / screaming eagle models without modification.  Please check with us first if you have any questions about fitment.

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 kit includes all of the components for a fully functional, fully height adjustable rear air suspension.   With these shocks, you can ride with zero air pressure without rubbing. That means if you hit a huge bump or if you ever lost air pressure for any reason you can still ride without rubbing your tire against your fender (on most '09-Later models, or '08-earlier models with stock rear tire).  No need to pay more for another system, and no need to have someone else install.  This system can be installed by anyone with basic tools and basic-to-moderate auto/motorcycle knowledge and experience, and includes easy to follow instructions and wiring/plumbing diagram, and we will help you with any technical questions you have.  In some cases, depending on location and bike model, some mild fabrication may be necessary to mount some components, but normally this system comes with everything you need for an easy installation.  Kit comes as pictured, but will vary from year-to-year.  Switch is a mini toggle switch that mounts in a 1/4" hole, and includes a protective waterproof boot.  Please note the optional handlebar grip switch will not fit 2015-up Road Glide 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. 

Steel shocks measure 9.5" collapsed, 13.25" extended (measured bolt-center to bolt-center)

Aluminum shocks measure 9.5" collapsed, 13.75" extended (measured bolt-center to bolt-center) 

What's the difference between the steel and aluminum shocks?  Steel shocks have a pretty basic design inside and out.  This keeps the price low, and the shocks still ride well and are very reliable.  The aluminum shocks have a more advanced design inside and out - This allows for optimum reliability, as well as the most comfortable ride available and the best performance available.  They have a wider range of comfortable travel, so they're very easy to adjust and most people find that they can ride lower with these shocks.  If you are looking for the best air shocks available for your bike, these aluminum shocks are what you are looking for.
