The Progressive Suspension 412 Series Shock is designed specifically for Harley Dyna models, offering a simple and durable upgrade to your motorcycle's suspension system. With a five-position cam style spring load preload adjuster, riders can easily fine-tune their ride for optimal comfort and handling. This feature allows for quick adjustments to accommodate different riding conditions or load requirements, providing a customizable experience without the need for additional tools or complex procedures. The shocks are available in various styles, including full show-chrome or black covers, as well as chrome or black springs and end caps, allowing riders to personalize their bike's appearance to match their style preferences.
Constructed in the USA, these shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility and precise installation. When installing on '86-'15 XL models, some modifications or spacing of the chain or belt guard may be necessary to ensure proper clearance and avoid contact with other components. The 11-inch length of these shocks can influence the bike's handling characteristics; slightly longer shocks may provide quicker steering by altering the head angle, while slightly shorter ones can result in slower steering. Heavy-duty applications are recommended for bikes operated near maximum load capacity over 50% of the time, ensuring durability and performance under demanding conditions.
Before purchasing or installing shocks that differ from OEM specifications, it is important to verify that wheel travel and clearance issues, such as swingarm or exhaust contact, are addressed. Proper compatibility ensures safe operation and prevents potential damage to the motorcycle. Whether you're upgrading for improved ride quality or customizing your Harley Dyna's look, the Progressive Suspension 412 Series Shock offers a reliable, high-performance solution suited for a variety of riding styles and preferences.
