Progressive Suspension 412 Series Shock - 11 Inch Standard Chrome for Harley Dyna Models 412-4037C

412 Series Shock - 11" - Standard - Chrome - Dyna

The Progressive Suspension 412 Series Shock is specifically designed to enhance the ride quality of Harley Dyna models, offering a cost-effective upgrade to your motorcycle's suspension system. Featuring a durable and simple design, these shocks are built for longevity and reliable performance. The 412 Series includes a five-position cam-style spring preload adjuster that allows riders to easily dial in their desired ride height and firmness for various riding conditions. Made in the USA, these shocks are available with multiple style options, including full show-chrome or black covers, as well as chrome or black springs and end caps, allowing customization to match your bike's aesthetic.
Each shock is measured from center of eyelet to center of eyelet, ensuring precise fitment. When installing on '86-'15 XL models, some modifications to the chain or belt guard may be necessary to ensure proper clearance. Slight variations in length compared to stock shocks can affect steering response, with longer shocks providing quicker steering and shorter shocks offering a more relaxed feel. Heavy-duty applications are recommended for bikes frequently operated near maximum load capacity, typically over 50% of the time. Before upgrading, confirm that your wheel travel can accommodate length modifications without interfering with components such as the exhaust, swingarm, axle, or chain/belt guard, to maintain safe and optimal performance.
Designed for riders seeking improved handling and ride comfort, the Progressive Suspension 412 Series shocks are a versatile choice for Harley Dyna owners. These shocks are engineered to provide a smooth, controlled ride while maintaining compatibility with a variety of customization options, ensuring your motorcycle performs at its best under diverse riding conditions.
