Progressive Suspension 412 Series Shock - 13-Inch Heavy Duty Black for Harley FXD 412-4084B

The Progressive Suspension 412 Series Shock is engineered specifically for Harley Davidson FXD models, offering a reliable and cost-effective upgrade to enhance your motorcycle's suspension performance. With its simple yet durable design, this shock absorber provides noticeable improvements in ride comfort and handling, making it an excellent choice for riders seeking both performance and value. The shock features a five-position cam-style spring preload adjuster, allowing riders to easily fine-tune their suspension setup to match riding conditions and personal preferences. Whether you're commuting or tackling rougher terrain, this adjuster helps you achieve a tailored ride quality with minimal effort.
Constructed in the USA, the 412 Series Shock is available in various styles, including full show-chrome or black covers, along with chrome or black springs and end caps, to match your bike’s aesthetic. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility and proper installation. When installing on '86-'15 XL models, some modifications or spacers may be necessary to accommodate the chain or belt guard for proper clearance. It’s important to note that a shock that is slightly longer than stock can slightly alter the head angle, resulting in quicker steering, while a slightly shorter shock can slow steering slightly. The Heavy Duty version is recommended for bikes frequently operated near the maximum load rating, providing enhanced durability and performance under demanding conditions.
Before selecting shocks with lengths different from the OEM, confirm that your wheel travel can accommodate the change without causing contact issues with the swingarm, axle, exhaust, chain/belt guard, or tires. Proper installation and compatibility are essential to ensure safe and optimal riding performance. The Progressive Suspension 412 Series Shock is designed to deliver improved handling, greater stability, and a smoother ride, making it a smart upgrade for Harley FXD owners seeking dependable suspension performance.
