Progressive Suspension 412 Series Shock for Harley FXD - 12.5 Inch Standard Black

The Progressive Suspension 412 Series Shock (Part Number: 412-4038B) is engineered specifically for Harley-Davidson FXD models, offering a cost-effective upgrade to enhance your motorcycle's suspension performance. With a durable design, these shocks are built to withstand rigorous riding conditions while providing improved ride quality. The 412 Series features a five-position cam-style spring preload adjuster, allowing riders to easily dial in their preferred ride height and stiffness for customized comfort and handling. Made in the USA, these shocks are a reliable choice for riders seeking a balance between performance and affordability.
These shocks are available in multiple style options, including full show-chrome or black covers, as well as chrome or black springs and end caps, enabling you to match your bike's aesthetic. They are measured from center-of-eyelet to center-of-eyelet, ensuring precise fitment on Harley FXD models. When installing on '86-'15 XL models, it may be necessary to modify or space the chain or belt guard for proper clearance. Slightly longer shocks can provide a quicker steering response by altering the head angle, whereas slightly shorter shocks may result in a more relaxed steering feel. Heavy-duty applications are recommended for bikes operating near maximum load capacity over 50% of the time.
Before purchasing or installing shocks that differ from the OEM length, confirm that your wheel travel and clearance are sufficient to prevent contact with the exhaust, swingarm, axle, chain or belt guard, or tires. Proper compatibility ensures optimal performance and safety, making the Progressive Suspension 412 Series Shock a versatile upgrade for Harley enthusiasts seeking improved ride dynamics and style.
