Arnott’s new adjustable Air Suspension System for the Harley-Davidson Softail ® has been custom designed for the Softail frame to provide the rider with superior control, ride comfort and height adjustability. The kit, featuring Arnott’s TruAIR technology, includes a rugged air spring bladder and is not an air cylinder or air-assisted unit. Arnott includes a powerful compressor and black anodized cover which attaches to the regulator rectifier to hide and protect the compressor.
