Since its inception in 1982, Progressive Suspension has evolved into the premier brand of motorcycle suspension parts in the U.S. This California-based company is also a top-class OE supplier to domestic manufacturers. Its components are commonly found on many production and custom bikes, designed to offer the comfort and performance riders expect from America’s largest motorcycle suspension maker. The system that provides the connection between the rider and the road is what determines the general riding experience, so the company’s engineers go to great lengths to create the perfect suspension setup.

Progressive Suspension shocks are made using state-of-the-art tooling while being tested on dyno and in real-world conditions. Each and every unit is built under strict quality control at every stage. This is how the company’s team makes sure riders feel comfortable and confident on the road with better stability and more control. Progressive Suspension Harley-Davidson shocks feature high pressure gas monotube construction. A threaded body and rebound adjustment allow you to choose the most suitable setup for the current load conditions. These shocks are hand built and covered by an industry-leading warranty.

Progressive Suspension fork springs minimize front dive under braking, improve cornering stability, and prevent bottoming out. Stock springs are non-adjustable, but riders can upgrade to the brand’s fork monotube kit with preload adjusters that allows them to fine tune the damping action by simply twisting the cap. Whether you are looking to improve ride quality and handling, slam your bike or add some ground clearance, enjoy the benefits of the latest suspension technology, or just replace worn-out parts, you can’t do better than this brand which is well-known for the quality of its products and a host of industry firsts.
