Progressive Suspension 412 Series Shock for Harley-Davidson, 13.5 inches, Black - Part #412-4003B

The Progressive Suspension 412 Series Shock is engineered specifically for Harley-Davidson models, offering an affordable upgrade to enhance your motorcycle's suspension performance. Designed with a simple yet durable construction, these shocks provide reliable support for a smoother ride and improved handling on the road. The five-position cam-style spring preload adjuster allows you to easily customize the ride height and firmness to suit your riding style and load conditions, ensuring optimal comfort and control. Made in the USA, the 412 Series shocks feature a sleek black finish that complements a variety of motorcycle styles and customizations. They are suitable for use on most Harley models and are approved for road use, providing confidence in their safety and durability. These shocks are measured from center-of-eyelet to center-of-eyelet, making them easy to install and compatible with a wide range of Harley-Davidson motorcycles. When installing on '86-'15 XL models, some modifications to the chain or belt guard may be necessary to achieve proper clearance. The slightly longer or shorter shocks can subtly alter the head angle, resulting in either quicker or slower steering response, allowing riders to tailor their handling preferences. Heavy-duty applications are recommended for bikes frequently operated near the maximum load rating, ensuring longevity and performance under demanding conditions. Before replacing OEM shocks with different lengths, verify that wheel travel and clearance are appropriate to prevent contact with the exhaust, swingarm, axle, or tire, maintaining safe operation and optimal suspension function.
