Progressive Suspension 412 Series Shock - 11 Inch Heavy Duty Black for Harley Models

Upgrade your Harley-Davidson motorcycle's suspension with the Progressive Suspension 412 Series Shock, Part Number 412-4067B. Designed specifically for Harley models, this shock absorber features a simple yet durable construction that offers an affordable way to enhance ride comfort and handling. Its black finish provides a sleek appearance that complements various bike styles, while the heavy-duty design ensures reliable performance under demanding riding conditions. Made in the USA, these shocks are built to meet strict quality standards and are suitable for both street and light off-road applications.
Equipped with a five-position cam-style spring load preload adjuster, this shock allows you to easily fine-tune your ride for optimal comfort and stability. Whether you're cruising on highways or tackling uneven terrain, the adjustable preload helps you dial in the suspension to your preference. It is important to note that some models may require modifications or spacing of the chain or belt guard to ensure proper clearance during installation. This compatibility consideration helps prevent contact issues that could affect your motorcycle's performance.
The 412 series shocks are measured from center-of-eyelet to center-of-eyelet, providing consistent and predictable handling. Slight variations in length—either longer or shorter than stock—can subtly alter the head angle, offering quicker or slower steering responses to match your riding style. For heavy-duty applications, these shocks are recommended for bikes operated near or at the manufacturer's maximum load rating more than half the time, ensuring durability and performance under increased strain. Before installing shocks that differ from OEM length, verify that your wheel travel and clearance are adequate to avoid contact with swingarm, exhaust, or other components, especially when adjusting for different riding conditions or custom setups.
