Product Details

These Progressive 412 Series shocks are a solid option for improving the suspension on a wide range of Harley-Davidson Sportster models, including the XL1200X Forty-Eight and XL883N Iron 883. They offer a noticeable upgrade over stock, providing smoother and more consistent damping for a more comfortable ride, whether you're cruising around town or hitting the open road.

Built with a double-wall steel body and high-pressure gas charging, these shocks are made to last and perform reliably. The multi-stage velocity-sensitive valving adjusts automatically to road conditions, ensuring a stable feel. You can also fine-tune your ride using the five-position cam-style preload adjuster, allowing you to set the suspension stiffness based on your weight or riding style.

The chrome finish and chrome springs give your bike a classic look, and the 11-inch length is a common fitment for many Sportster applications. If you're looking to enhance your motorcycle's handling and comfort with a well-built, adjustable shock, the 412 Series is a popular choice.
