Progressive Suspension 412 Series Shock - 12 Inch Heavy Duty Black (Part Number: 412-4069B)

412 Series Shock - 12" - Heavy Duty - Black

The Progressive Suspension 412 Series Shock is specifically engineered for Harley motorcycle models, providing a cost-effective upgrade to enhance your bike's suspension performance. Designed with simplicity and durability in mind, these shocks feature a five-position cam style spring preload adjuster that allows riders to easily fine-tune their ride for optimal comfort and handling. Whether you're looking to improve stability on rough roads or achieve a smoother ride, the 412 Series shocks deliver reliable performance tailored to your needs.

Available in multiple styles, including full show-chrome or black covers, along with chrome or black springs and end caps, these shocks offer customizable aesthetics to match your motorcycle's look. Made in the USA, each shock is measured from center-of-eyelet to center-of-eyelet, ensuring accurate fitment for compatible Harley-Davidson models. When installing on '86-'15 XL models, some modifications to the chain or belt guard may be necessary to provide proper clearance and prevent contact issues. It's important to verify wheel travel and clearance before installation, especially if selecting shocks that differ from OEM length, as this can affect steering and overall handling.

Heavy-duty applications are recommended for bikes frequently operated near the manufacturer's maximum load capacity, often over 50%. Slight variations in shock length—either longer or shorter than stock—can influence steering geometry, resulting in either quicker or slower steering response. Proper installation and adjustment ensure that your Harley remains stable and responsive on all types of terrain, making the Progressive Suspension 412 Series shocks an excellent choice for riders seeking durability and performance enhancement in a premium suspension component.
