Progressive Suspension 412 Series Shock for Harley FXD - 14 inch Heavy Duty Black | Part 412-4086B

The Progressive Suspension 412 Series Shock (Part #412-4086B) is designed to enhance the suspension performance of Harley-Davidson FXD models. Built with durability and simplicity in mind, these shocks provide a cost-effective upgrade that can improve ride comfort and stability. Their robust construction ensures reliable performance under various riding conditions, making them a popular choice among riders seeking a practical suspension solution.

Features include a five-position cam-style spring preload adjuster that allows riders to easily select the optimal ride height and firmness for their preferences or load conditions. This adjustability ensures a personalized riding experience while maintaining the shock’s straightforward design. Available in multiple styles, such as full show-chrome or black covers, with options for chrome or black springs and end caps, these shocks can be customized to match your bike’s aesthetic.

Made in the USA, the shocks are measured from center-of-eyelet to center-of-eyelet, ensuring proper fitment for Harley FXD models. When installing on models from 1986 to 2015, some modifications to the chain or belt guard may be necessary to ensure proper clearance. Slightly longer shocks can alter the head angle, resulting in quicker steering, while shorter shocks may slow steering response. Heavy-duty applications are recommended for bikes frequently operated at or near maximum load ratings, ensuring longevity and performance under demanding conditions.

Before customizing your suspension with shocks that differ from stock length, confirm that your wheel travel and clearance points—such as swingarm, axle, exhaust, and chain or belt guard—are compatible to avoid contact issues. Proper installation and adjustment will enhance your motorcycle's handling, comfort, and overall riding experience, making the Progressive Suspension 412 Series Shock a reliable upgrade for Harley FXD owners.
