Collection: Progressive Suspension Shock Absorbers for Harley-Davidson Motorcycles

There is a brand that takes its name directly from the technology that best characterizes them: progressive suspension. Progressive Suspension was founded in 1982, conceived by industry veterans with a single goal: to create the best performing motorcycle suspension possible. Today, it is the largest aftermarket motorcycle suspension manufacturer in the United States and holds several OEM (Original Equipment Manufacturer) supply contracts. The brand's progressive spring load technology means that the spring does not react to the load uniformly, but with gradually increasing resistance – this provides a smoother, more balanced ride over smaller road imperfections, while also offering adequate support under heavier loads (e.g., with a passenger). In our offering, you will find Progressive Suspension shock absorbers for Harley-Davidson Sportster, Touring, Softail, and Dyna models, ranging from the reliable, good value-for-money 412 series to the premium 944 Ultra Touring and Ultra Low versions with Frequency Sensing Technology (FST), which can lower the motorcycle by 1-2". Fork springs are also available for almost all major motorcycle brands, as well as complete lowering systems. Quality Progressive shock absorbers are manufactured with nitrogen gas-charged, multi-stage valving, and adjustable preload, alongside precise testing and shock dynamometer development. Whether your goal is an affordable, reliable upgrade or a premium, lowered touring setup, Progressive Suspension provides exactly the comfort and stability that riders have trusted for four decades.
