Progressive Suspension 412 Series Shock - 13 Inch Heavy Duty Black for Harley FL Models

The Progressive Suspension 412 Series Shock, part number 412-4077B, is designed specifically for Harley Davidson FL models, offering a reliable upgrade to your motorcycle's suspension system. Constructed with durability and performance in mind, this shock features a simple yet robust design that enhances ride comfort and handling. Its heavy-duty construction makes it suitable for riders who frequently operate at or near the motorcycle's maximum load capacity, ensuring a smoother and more controlled ride under demanding conditions. The 13-inch length provides a slight increase over stock shocks, which can subtly influence steering responsiveness by slightly quickening the head angle, thus improving maneuverability.

One of the key features of this shock is its five-position cam-style spring preload adjuster, allowing riders to easily dial in the ideal ride height and firmness for their preferences and riding conditions. This level of adjustability ensures optimal handling whether you're cruising on highways or tackling rougher terrain. The shocks are available with multiple styling options, including full show-chrome or black covers, and both chrome or black springs and end caps, allowing you to customize the look to match your bike's aesthetic. Made in the USA, these shocks are built to high-quality standards for long-lasting performance and reliability.

Installation may require modifications, such as spacing the chain or belt guard on '86-'15 XL models, to ensure proper clearance. It's important to verify that your wheel travel can accommodate shocks of a different length without causing contact issues with the swingarm, exhaust, or other components. Whether upgrading for better performance or style, the Progressive Suspension 412 Series Shock provides a cost-effective solution that improves your motorcycle’s handling, stability, and ride quality, making it a popular choice among Harley riders seeking heavy-duty suspension components.
