Harley-Davidson® introduced a new line of their popular Softail® model in 2018. Among other changes they replaced the horizontally mounted rear suspension with a new monoshock. Arnott engineers immediately went to work on improving the ride by designing an adjustable Ultimate Ride Air Suspension kit for the new Softail. The new kit offers TruAIR® Technology with a rugged Goodyear multi-ply air spring sleeve which is coupled with a large FOX® nitrogen-charged, monotube shock absorber. Arnott’s Air Shock provides the rider with superior control, ride comfort and greater height adjustability.Arnott pairs your shock with a small but powerful compressor, application-specific mounting bracket, and air distribution valve block which includes a muffler to control how fast air is released. Each kit includes everything you need for a fast and flawless installation including an installation manual, fused wiring harness and relay assembly, chrome/black handlebar-mounted inflation switch, all necessary tubing, wiring, cable ties, fittings, and mounting accessories. Each shock is custom-crafted and rigorously tested in Arnott’s Florida manufacturing facility and is backed by Arnott’s Limited Lifetime Warranty. ELEVATE YOUR RIDE.™Fits all 2018-2021 Softail models, including FXDR models.
