Product Details

Starting with a doublewall steel body construction, these Progressive 412 Series shocks are built to last and offer a noticeable improvement over stock suspension. They utilize nitrogen-charged, multi-stage velocity-sensitive valving to ensure consistent damping performance, meaning your ride stays smooth and controlled whether you're cruising or hitting rougher patches. This well-built design is a solid option for riders looking to enhance their motorcycle's handling and comfort.

These 11-inch black shocks are designed to fit a wide range of Harley-Davidson Dyna models, including popular bikes like the FXD Dyna Super Glide, FXDB Street Bob, and FXDWG Dyna Wide Glide. The five-position cam-style preload adjuster is a key feature, allowing you to easily dial in your suspension to match your riding style and load, whether you're carrying a passenger or riding solo. You can choose between standard or heavy-duty progressive rate springs, available in chrome or black, to further customize the look and feel of your ride.
