The Progressive Suspension 412 Series Shock, part number 412-4035C, is specifically designed for Harley-Davidson models to enhance suspension performance with a simple and durable design. This 12-inch shock provides a cost-effective upgrade that can improve ride stability and comfort, making it an excellent choice for riders seeking reliable performance. The shock features a five-position cam-style spring preload adjuster, allowing you to easily dial in your desired ride height and handling characteristics for a customized ride experience. Its chrome finish not only adds a sleek aesthetic but also ensures durability against the elements, making it suitable for both street and occasional off-road use. All shocks are made in the USA and measured from center-of-eyelet to center-of-eyelet, ensuring precise fitment and compatibility with Harley-Davidson models from 1986 to 2015.
Installation should consider potential modifications, such as adjusting or spacing the chain or belt guard on certain XL models to prevent clearance issues. Slightly longer shocks may alter the head angle, resulting in quicker steering response, while shorter shocks can produce a marginally slower steering feel. For heavy-duty applications or bikes operated near maximum load capacity over 50% of the time, a heavy-duty version is recommended to ensure longevity and performance. Before installing shocks that differ in length from OEM specifications, confirm that wheel travel and clearance with components like the swingarm, exhaust, and tires are adequate to avoid contact or damage. This versatile shock is suitable for riders looking to enhance both the aesthetic and functional aspects of their Harley-Davidson motorcycle, offering a reliable, adjustable, and visually appealing upgrade to stock suspension components.
