Upgrade your cruiser or touring bike's suspension with the Progressive Suspension 412 Series shocks. These nitrogen-charged shocks offer superior ride quality and handling, providing a comfortable and controlled experience on the road. With their classic chrome and black finish, they enhance both the performance and appearance of your motorcycle.

Description

The Progressive Suspension 412 Series shocks are engineered to automatically adjust to varying riding conditions thanks to their multi-stage, velocity-sensitive valving. Designed specifically for cruisers and touring bikes, these shocks feature a progressively wound steel spring that enhances handling and ensures a smooth ride. Fine-tune your suspension with the five-position cam-style preload adjuster, allowing you to dial in the perfect ride for your load and riding style. The heavy-duty (HD) applications are highly recommended for bikes frequently operated at or near their maximum load capacity. Built with quality materials and precise engineering, these shocks offer long-lasting performance and reliability. Before installing shocks differing from the OEM length, always confirm adequate wheel travel to avoid clearance issues.
