Progressive Suspension 412 Series Shock - 12 Inch Standard Black - Model 412-4068B

The Progressive Suspension 412 Series Shock is designed specifically for Harley-Davidson models, offering a cost-effective upgrade to enhance your motorcycle's suspension performance. Constructed with a simple yet durable design, these shocks provide reliable handling and improved ride quality. The 412 series features a five-position cam-style spring load preload adjuster, allowing riders to easily dial in their preferred ride firmness for different riding conditions and loads. Made in the USA, these shocks are built to meet high-quality standards and are suitable for a variety of Harley models, including the XL series from 1986 to 2015.
The shocks are available in multiple style options, such as full show-chrome or black covers, with either chrome or black springs and end caps, enabling customization to match your motorcycle’s aesthetic. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring proper fitment. It is important to note that some models may require modifications, such as adjusting or spacing the chain or belt guard, for proper clearance during installation. Slightly longer shocks can alter the head angle, resulting in quicker steering, while shorter shocks may slow steering responsiveness.
For heavy-duty applications, where bikes are operated near maximum load ratings over 50% of the time, these shocks are recommended to provide extra durability and performance. Before installation, ensure that changing shock length won't interfere with clearance issues like swingarm or axle contact with exhaust, chain or belt guards, or tires. Proper selection and installation of shocks can significantly impact your motorcycle’s handling, comfort, and overall riding experience, making the Progressive Suspension 412 Series a reliable choice for motorcycle enthusiasts seeking performance and customization.
