At the core of this system are two custom nitrogen charged FOX shock absorbers. Then, using a patent-pending design, Arnott adds a rugged Goodyear® air spring, ensuring superior comfort, ride quality, and durability. Arnott pairs your shocks with a small but powerful compressor, application-specific mounting bracket, and air distribution valve block which include a muffler to control how fast air is released. Each kit includes everything you need for a fast and flawless installation including Detailed Installation Manual, fused wiring harness and relay assembly, handlebar-mounted inflation switch, all necessary tubing, cable ties, fittings, bolt covers, and mounting accessories.
