Founded in 1982, Progressive Suspension® has evolved into the largest aftermarket motorcycle suspension manufacturer in the United States as well as a top tier supplier of suspension components to domestic OE customers. Their suspension systems can be found on premier customs, production trikes and just about any bike that's doing big miles across the US and for that matter the world. A team of ride control trained engineers use state of the art computers, shock dynos and real world testing to create the ideal suspension platform for your bike. From there, their state of the art manufacturing facility assembles and in many cases dyno tests each unit before it leaves the factory. Their quality control systems touch on each component from assembly to final stages and nothing gets in or out of the building without passing a rigorous inspection. High performance suspension is not limited to street machines, as their line up also includes an in depth line of shocks and fork springs for bikes dating back to the 50's as well as product for modern Adventure Touring bikes, Sport Bikes, ATV and UTV's.
