DIRTY AIR Basic Front and Rear Air Suspension System

For HD Touring models.  Complete rear system, and complete front system.  Includes 2 compressors with year specific mounting brackets, rear shocks, front air pistons and springs for applicable models, 2 dump manifolds, and all tubing/fittings/wiring etc to complete installation.  1 compressor operates the front, and one operates the rear.  Lifts most touring model bikes in approximately 13 seconds.  

Other option runs the complete system off of one compressor, and includes the proper valving to distribute flow up/down front/rear.  Front and rear operate separately, front takes approximately 13 seconds and rear takes approximately 13 seconds.  Please not this valving is not sufficient for incorporating an air tank!  Made to run as-is, not to add a tank!

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.

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, click here for MRI Customs Electric Center Stands

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.
