412 Series Shock - 12.5" - Heavy Duty - Black - H-D
The Progressive Suspension 412 Series Shock, model 412-4007B, is designed specifically for Harley-Davidson motorcycles, offering a reliable upgrade to enhance your bike's suspension performance. Its simple yet durable design makes it a cost-effective solution that improves ride quality and handling for both daily commuting and long-distance cruising.
This shock features a five-position cam-style spring preload adjuster, allowing riders to easily fine-tune suspension stiffness to match their riding preferences or load conditions. Made in the USA, it combines quality craftsmanship with versatility, available with options like full show-chrome or black covers, as well as chrome or black springs and end caps to match your bike’s aesthetic. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility and accurate installation.
When installing the 412 series shocks on Harley models from 1986 to 2015, some modifications may be required, such as adjusting or spacing the chain or belt guard for proper clearance. Slightly longer shocks can modify the head angle, resulting in quicker steering response, while slightly shorter shocks may produce a more relaxed steering feel. The shocks are suitable for heavy-duty applications, recommended for bikes frequently operated near the maximum load capacity. Before installing shocks that differ from OEM length, ensure your wheel travel can be adjusted without causing clearance issues with the swingarm, exhaust, or tires, and verify that the chain or belt guard is appropriately spaced.
Designed for durability and performance, the Progressive Suspension 412 Series Shock provides an excellent upgrade for Harley riders seeking improved handling, ride comfort, and customization options. Whether you're customizing your bike for style or function, these shocks deliver dependable performance tailored to your riding needs.
