Progressive Suspension 412 Series Shock - 12 inch Standard/Heavy Duty Black for Harley FXD 412-4046B

412 Series Shock - 12" - Standard/Heavy Duty - Black - FXD

The Progressive Suspension 412 Series Shock is engineered specifically for Harley-Davidson FXD models, offering a reliable upgrade to your motorcycle's suspension system. Designed with durability and performance in mind, these shocks feature a simple yet effective construction that enhances ride quality while maintaining cost efficiency. The 12-inch length provides an optimal balance between comfort and handling, making it suitable for a variety of riding conditions. These shocks include a five-position cam style spring preload adjuster, allowing riders to easily customize the suspension stiffness to match their preferences and riding style. Whether you're tackling daily commutes or longer road trips, the adjustable preload ensures a tailored ride experience. Made in the USA, the shocks are built to high standards of quality and durability, ensuring long-lasting performance under demanding conditions. Some models are approved for road use, but it is recommended to consult the latest certification details for compliance. The shocks are available in multiple styling options, including full show-chrome or black covers, with either chrome or black springs and end caps, allowing riders to customize their bike’s appearance to match their aesthetic. When installing these shocks on '86-'15 XL models, modifications to the chain or belt guard may be necessary to ensure proper clearance and prevent contact issues. The slightly longer or shorter shocks compared to stock can alter the motorcycle's head angle, providing quicker or slower steering responsiveness accordingly. Heavy-duty applications are advised for bikes operated near maximum load ratings over 50% of the time, ensuring the suspension can handle increased weight demands. Before installing shocks that differ from the OEM length, verify that wheel travel can be adjusted without clearance issues such as swingarm or axle contact with the exhaust, chain or belt guard, or tire interference. These features make the Progressive Suspension 412 Series Shock a versatile, reliable upgrade for Harley FXD owners seeking improved ride quality and customization options.
