412 Series Shock - 11.5" - Heavy Duty - Black
The Progressive Suspension 412 Series Shock, part number 412-4066B, is designed specifically for Harley-Davidson models, offering a reliable and cost-effective upgrade to your motorcycle's suspension system. This shock absorber features a simple yet durable construction that enhances ride quality and handling, making it suitable for both everyday riding and more demanding conditions. Its black finish provides a sleek appearance that complements a variety of Harley styling options, and it is made in the USA to ensure quality and craftsmanship. The 412-4066B is equipped with a five-position cam style spring load preload adjuster, allowing riders to easily fine-tune their suspension settings for optimal comfort and performance. This adjuster makes it straightforward to dial in the ride, whether you prefer a softer or stiffer suspension response. The shock's design includes features that are approved for road use, but it is advisable to consult the latest certification for specific compliance details. Measuring from eyelet to eyelet, this shock is tailored for models requiring an 11.5-inch length, with considerations for potential modifications when installing on certain Harley models from 1986 to 2015, such as adjusting or spacing the chain or belt guard for proper clearance. The length variation can subtly influence steering characteristics; a slightly longer shock may result in quicker steering, while a shorter one could lead to slower handling. Heavy-duty applications are recommended for bikes frequently operated at or near maximum load capacity, typically over 50% of the time. Before installing shocks that differ from the OEM length, it is crucial to verify that wheel travel and clearance issues, including swingarm, axle, exhaust, chain or belt guard, and tire contact, are thoroughly checked to prevent interference and ensure safe operation. Available in multiple style options, including full show-chrome or black covers, and either chrome or black springs and end caps, this shock provides versatile aesthetic choices to match your Harley's look. Overall, the Progressive Suspension 412 Series Shock offers a durable, adjustable, and visually appealing upgrade that enhances your motorcycle’s ride quality and handling performance.
