Progressive Suspension

Progressive Suspension bills itself as the largest aftermarket motorcycle suspension maker in the United States, founded in 1982. The company designs and builds rear shocks, fork springs, cartridge kits and complete front-end upgrades for Harley-Davidson, metric cruisers and a wide range of street bikes.

Its engineers use shock dynos and real-world testing to tune ride quality and control, and many units are dyno-tested before they leave the factory. Riders choose Progressive Suspension to improve comfort, handling and stance, whether smoothing out a rough-riding bagger or dialing in a custom build. Give us your bike, weight and riding style, we'll spec spring rates that actually fit you.
