412 Series Shock - 13" - Heavy Duty - Black - FL

The Progressive Suspension 412 Series Shock is engineered specifically for Harley-Davidson FL models, offering a reliable and cost-effective upgrade to your motorcycle's suspension system. Designed with simplicity and durability in mind, these shocks feature a five-position cam-style spring preload adjuster that allows you to easily fine-tune your ride for optimal comfort and handling. Whether you're riding daily or tackling long-distance journeys, these shocks are built to enhance your motorcycle's performance and stability.

Constructed in the USA, the 412 Series shocks are available in various styles, including full show-chrome or black covers, and come with either chrome or black springs and end caps to match your aesthetic preferences. These shocks are measured center-of-eyelet to center-of-eyelet, ensuring compatibility with a range of Harley models. When installing on '86-'15 XL models, some modifications to the chain or belt guard may be necessary to ensure proper clearance. It is important to verify that your wheel travel can accommodate shocks of different lengths to prevent contact issues with the swingarm, exhaust, or tires. Slightly longer shocks can provide quicker steering by altering the head angle, while shorter shocks may result in slightly slower steering. Heavy-duty applications are recommended for bikes frequently operating near maximum load capacities.

Designed for versatility and performance, these shocks are approved for road use, adhering to current certification standards. Proper installation and adjustment will improve your motorcycle's ride quality, handling, and stability, making the Progressive Suspension 412 Series Shock an excellent upgrade for Harley enthusiasts seeking durability and customizable performance.
