The Progressive Suspension 412 Series Shock, part number 412-4062B, is designed specifically for Harley-Davidson models, offering a cost-effective upgrade to enhance your motorcycle's suspension performance. With a simple yet durable design, these shocks are built to withstand the rigors of everyday riding while providing a smooth and controlled ride. The 11-inch length is suitable for a variety of Harley models, contributing to improved handling and comfort.
Features include a five-position cam-style spring preload adjuster, allowing riders to easily fine-tune their suspension setup for different loads and riding conditions. This adjustability ensures optimal ride quality whether you're cruising solo or with a passenger and gear. Some versions of these shocks are approved for road use, and it is recommended to refer to the latest certification details to confirm compliance. The shocks are available in multiple style options, including full show-chrome or black covers, with either chrome or black springs and end caps, allowing customization to match your bike’s aesthetic.
Made in the USA, these shocks are measured from center-of-eyelet to center-of-eyelet, ensuring proper fitment. When installing on '86-'15 XL models, modifications such as spacing the chain or belt guard may be necessary for proper clearance. Slight adjustments in shock length—either longer or shorter than stock—can subtly alter the head angle, affecting steering response; longer shocks may provide quicker steering, while shorter shocks can result in a slightly slower turn-in. Heavy-duty applications are recommended for bikes operated at or near the maximum load rating over 50% of the time.
Before purchasing or installing shocks that differ from the OEM length, verify that your wheel travel will not cause clearance issues with components such as the swingarm, axle, exhaust, chain/belt guard, or tires. Proper selection ensures safe operation and optimal handling, making the Progressive Suspension 412 Series Shock an excellent upgrade for enhancing your Harley-Davidson's ride quality and customization options.
