About this product
Upgrade your cruiser or touring bike's suspension with the Progressive Suspension 412 Series shocks. These shocks provide a superior ride and improved handling thanks to their progressively wound steel springs and nitrogen-charged design. With a classic chrome and black finish, they offer both performance and style.
Description
The Progressive Suspension 412 Series shocks are engineered to automatically adjust to varying riding conditions using multi-stage, velocity-sensitive valving. These shocks deliver a comfortable and controlled ride, whether you're cruising down the highway or navigating winding roads. The progressively wound steel spring enhances handling and absorbs bumps effectively. A five-position cam-style preload adjuster allows for fine-tuning the ride to suit your individual preferences and load. Designed specifically for cruiser and touring bikes, the 412 Series shocks are a reliable and high-performing upgrade. Heavy Duty (HD) versions are available and recommended for bikes consistently operated at or near their maximum load capacity. Proudly made in the USA, these shocks ensure lasting quality and performance. Their extended length is 11.00".
