Progressive Suspension 412 Series Shock - 12.5 Inch Standard Chrome for Harley FLH/T Models

The Progressive Suspension 412 Series Shock, designed specifically for Harley-Davidson FLH and T models, offers an affordable upgrade to enhance your motorcycle's suspension performance. Measuring approximately 12.5 inches from center-of-eyelet to center-of-eyelet, this shock provides a balanced ride quality suitable for a variety of riding conditions. Its simple yet durable design ensures long-lasting performance, making it an ideal choice for riders seeking reliability and improved handling. Crafted with quality materials in the USA, this shock is built to withstand demanding riding conditions while maintaining ease of installation and adjustment.
Featuring a five-position cam-style spring load preload adjuster, the 412 Series allows riders to easily dial in their preferred ride height and firmness, accommodating different loads and riding styles. This adjustability helps optimize comfort and stability, whether you're cruising on highways or navigating rougher terrain. Some versions of these shocks are approved for road use, but it is recommended to consult the latest certification for compliance details. The shocks are available with various styling options, including full chrome or black covers, and matching chrome or black springs and end caps, allowing customization to match your bike’s aesthetic.
When installing these shocks on 1986-2015 XL models, modifications such as spacing the chain or belt guard may be necessary to ensure proper clearance. Slight variations in length—either longer or shorter than stock—can subtly influence the head angle, affecting steering responsiveness. Heavier duty applications are advisable for bikes frequently operated near maximum load ratings, providing additional durability and support. Before installation, confirm that altering wheel travel won't cause clearance issues with the swingarm, exhaust, chain or belt guard, or tires. Overall, the Progressive Suspension 412 Series Shock enhances your Harley's ride quality with straightforward adjustability and robust construction, making it a reliable upgrade for both daily riding and long-distance touring.
