Progressive Suspension 412 Series Shock for Harley-Davidson - 11.5 inch - Black - Model 412-4006B

The Progressive Suspension 412 Series Shock (Part Number 412-4006B) is engineered specifically for Harley-Davidson models, offering an affordable upgrade to enhance your motorcycle's suspension performance. Designed with a simple yet durable construction, these shocks provide a reliable solution for riders seeking improved ride quality and handling. The five-position cam-style spring preload adjuster allows you to easily customize the ride height and firmness, ensuring optimal comfort and control tailored to your riding style and load conditions. Made in the USA, these shocks are built to high standards and are available in various styles, including full show-chrome or black covers, as well as chrome or black springs and end caps to match your bike's aesthetic. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring proper fitment for Harley models. When installing on '86-'15 XL models, it may be necessary to modify or space the chain or belt guard to ensure proper clearance. Slightly longer shocks than stock can influence the head angle, resulting in quicker steering, while shorter shocks may slow steering response. Heavy-duty applications are recommended for bikes routinely operated near the maximum load rating, often exceeding 50% of the manufacturer's capacity. Before purchasing shocks that differ from the OEM length, verify that wheel travel adjustments won't cause clearance issues with components like the swingarm, axle, exhaust, chain/belt guard, or tires. These shocks are suitable for road use, with some models approved for street riding, providing a cost-effective way to improve your Harley's suspension performance and ride quality.
