The Progressive Suspension 412 Series Shock is specifically designed for Harley-Davidson FL models, offering a cost-effective upgrade to enhance your motorcycle's suspension performance. With a simple yet durable design, these shocks are built to withstand demanding riding conditions while providing improved ride quality. The 412 series features a five-position cam-style spring preload adjuster, allowing riders to easily customize the suspension setup for varying loads and riding preferences, ensuring optimal comfort and handling. Crafted in the USA, these shocks are available in various styles, including full show-chrome or black covers, with chrome or black springs and end caps, enabling you to match your bike’s aesthetic preferences.
The shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility with your Harley. When installing on models from 1986 to 2015, some modifications to the chain or belt guard may be necessary to ensure proper clearance, especially if the shocks are slightly longer or shorter than stock. A longer shock can slightly alter the head angle and provide quicker steering response, while a shorter shock may result in a slightly slower steering feel. Heavy-duty applications are recommended for bikes operated near or at their maximum load capacity over 50% of the time, ensuring durability and performance under demanding conditions.
Before purchasing or installing shocks that differ from OEM length, it’s essential to verify that your wheel travel and clearance are adequate to prevent contact with the exhaust, swingarm, axle, chain or belt guard, or tires. These shocks are approved for street use and are designed to provide consistent performance, durability, and ride quality, making them an excellent upgrade for Harley enthusiasts seeking reliability and enhanced handling.
