Progressive Suspension 412 Series Shock for Harley Dyna - 12 Inch Standard Chrome (Part #412-4042C)

The Progressive Suspension 412 Series Shock is specifically designed for Harley Dyna models, offering a simple yet durable upgrade that enhances your motorcycle's suspension performance. Built with quality craftsmanship, these shocks provide a cost-effective way to improve ride comfort and handling. The 12-inch length and versatile styling options, including full chrome or black covers and springs, allow you to customize the look of your motorcycle while maintaining optimal performance. Made in the USA, these shocks are a reliable choice for riders seeking durability and quality.
Featuring a five-position cam-style spring load preload adjuster, the 412 Series shocks enable easy customization of ride stiffness to suit various riding conditions. Whether you're navigating city streets or taking on rougher terrain, adjusting the preload ensures a smoother and more controlled ride. These shocks are designed with compatibility in mind; when installing on '86-'15 XL models, some modifications to the chain or belt guard may be necessary to ensure proper clearance. It's important to verify that your wheel travel can accommodate shocks of different lengths without causing contact issues with the swingarm, exhaust, or tires.
Offering options for slightly longer or shorter shocks, the 412 Series can subtly alter your motorcycle's head angle, resulting in quicker or slower steering responses based on your preferences. For heavy-duty applications or bikes operated at or near maximum load capacities over 50% of the time, a recommended heavy-duty version is available to ensure longevity and performance. Always confirm that any non-stock shocks will not interfere with other components or clearance points, and consult your motorcycle's specifications before making modifications. These shocks are approved for road use, ensuring compliance with safety standards and providing confidence during everyday riding.
