Arnott's stylish new chrome rebound adjustable FOX? Air Suspension System has been custom designed for Harley-Davidson Touring models to give the rider superior control, additional ride comfort settings and fast ride height adjustability. The FOX shock's custom valving, designed for your motorcycle, provides you with a safe and comfortable ride. Arnott's patent-pending kit offers TruAIR technology with a rugged Goodyear air spring bladder and shock damper design, not an air cylinder or air-assisted unit. For added ride comfort this kit includes FOX's adjustable rebound control dial so you can quickly and easily adjust your shocks' internal damping characteristics ? a feature not found elsewhere in the air suspension market.
