Progressive Suspension 412 Series Shock - 13 Inch Heavy Duty Black for Harley-Davidson 412-4020B

The Progressive Suspension 412 Series Shock is engineered specifically for Harley-Davidson models, offering a simple yet durable upgrade to your motorcycle's suspension system. Designed with performance and longevity in mind, this shock provides a cost-effective way to enhance ride quality and handling. Featuring a five-position cam-style spring preload adjuster, it allows riders to fine-tune their suspension settings easily, accommodating various loads and riding conditions. The adjustable preload ensures a tailored ride experience, whether you're cruising or carrying extra gear. Constructed with quality materials and made in the USA, the 412 Series Shock combines reliability with style, available in a sleek black finish that complements a range of Harley models. Many options are available, 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. The product is measured from center-of-eyelet to center-of-eyelet, ensuring precise fitment. When installing on '86-'15 XL models, some modifications or spacers may be necessary to ensure proper clearance for the chain or belt guard, especially when using shocks slightly longer or shorter than stock. A longer shock can slightly alter the head angle, providing quicker steering, while a shorter shock may slow steering response slightly. Heavy-duty applications are recommended for bikes frequently operated near the manufacturer's maximum load rating, typically over 50% of the time. Before installation, confirm that your wheel travel can accommodate shocks of different lengths without causing clearance issues such as contact with the exhaust, swingarm, axle, or tires. This shock is an excellent upgrade for riders seeking improved suspension performance, durability, and a customizable ride, all backed by Progressive Suspension’s commitment to quality and American manufacturing standards.
