412 Series Shock - 11" - Heavy Duty - Black

The Progressive Suspension 412 Series Shock is specifically designed for Harley-Davidson models, offering a straightforward and durable upgrade to enhance your motorcycle's suspension performance. Crafted in the USA, these shocks feature a simple yet robust design that provides an economical solution to improve ride quality and handling. The 11-inch length and heavy-duty construction make them suitable for riders who frequently operate at or near the manufacturer's maximum load capacity, ensuring reliable performance under demanding conditions.
The adjustable preload feature, equipped with a five-position cam-style spring load, allows you to easily fine-tune your ride for optimal comfort and stability. Whether you're cruising or tackling rough terrain, this adjuster helps you dial in your suspension to match your riding style and load requirements. Refer to the most recent certification for current road approval status, as some models are approved for street use.
Available in multiple styles, including full show-chrome or black covers and springs with matching end caps, these shocks also offer options for chrome or black finishes to match your bike's aesthetic. When installing on '86-'15 XL models, you may need to modify or space the chain or belt guard to ensure proper clearance, especially if opting for shocks slightly longer or shorter than stock. Slight changes in length can influence steering characteristics, with longer shocks providing quicker steering and shorter shocks offering a more relaxed feel.
Heavy-duty applications are recommended for bikes frequently operated at high loads, while proper clearance checks are essential when choosing shocks different from OEM length to prevent contact issues with the swingarm, axle, exhaust, chain or belt guards, and tires. This ensures safe installation and optimal performance, making the Progressive Suspension 412 Series Shock a reliable upgrade for enhancing your Harley-Davidson's ride quality and handling.
