Progressive Suspension 412 Series Shock for Harley Dyna - 12.5 inch Chrome Model (Part #412-4038C)

The Progressive Suspension 412 Series Shock, designed specifically for Harley Dyna models, offers a simple yet durable upgrade to enhance your motorcycle's suspension performance. Crafted with quality in mind, these shocks feature a five-position cam-style spring preload adjuster, allowing riders to easily customize their ride for comfort and handling. Whether you prefer a full show-chrome finish or a black cover, these shocks are available in multiple style options, including chrome or black springs and end caps, to match your bike's aesthetic.
Made in the USA, the 412 Series shocks are measured from center-of-eyelet to center-of-eyelet, ensuring proper fitment on your Harley. When installing on models from 1986 to 2015, some modifications, such as spacing the chain or belt guard, might be necessary for clearance. Slight variations in shock length can influence steering dynamics: a longer shock can offer quicker steering, while a shorter one may slow the steering response. Heavy-duty applications are recommended for bikes regularly operated near maximum load capacity or carrying heavy loads.
Before purchasing shocks that differ from OEM length, confirm that wheel travel and clearance issues—such as swingarm, axle, exhaust, or tire contact—are addressed to prevent interference. These shocks are approved for road use, but it’s essential to verify current certifications. Enhance your motorcycle's ride quality and handling with the reliable, adjustable features of the Progressive Suspension 412 Series Shock, tailored for Harley Dyna riders seeking performance and style.
