Progressive Suspension 412 Series Shock for Harley FXD - 12 Inch Black Model 412-4042B

The Progressive Suspension 412 Series Shock, part number 412-4042B, is engineered specifically for Harley-Davidson FXD models, offering a reliable upgrade to your motorcycle's suspension system. Designed for durability and performance, these shocks feature a simple yet robust construction that enhances ride quality without adding unnecessary complexity. The black finish provides a sleek, understated look that complements a variety of Harley styling choices, and made in the USA, ensuring quality craftsmanship and reliability. These shocks are designed to be a cost-effective solution for riders seeking improved handling and comfort on the road or trail, with options available for both street and off-road applications. The 412 Series Shock is equipped with a five-position cam-style spring preload adjuster, allowing you to easily customize ride height and stiffness to suit your riding style and load conditions. This feature ensures your suspension responds precisely to your preferences, whether you’re carrying extra gear or riding solo. It’s important to note that some shocks in this series are approved for on-road use, but riders should verify current certification for their specific application. When installing these shocks on '86-'15 XL models, modifications to the chain or belt guard may be necessary to ensure proper clearance, especially if opting for a non-stock length. Slightly longer shocks can alter the head angle, providing quicker steering, while shorter shocks may slow steering response for a different handling feel. Heavy-duty applications are recommended for motorcycles operating near maximum load capacity over 50% of the time. Before purchasing shocks with different lengths than OEM, confirm that wheel travel and clearance issues, such as swingarm or tire contact, are addressed to prevent installation problems. This versatile suspension component provides an effective, customizable upgrade to improve your Harley-Davidson riding experience, combining durability, adjustability, and a sleek appearance. Whether you choose the full show-chrome or black covers, or select chrome or black springs and end caps, the Progressive Suspension 412 Series Shock is designed to meet the demands of serious riders seeking dependable performance and style.
