Progressive Suspension 412 Series Shock for Harley Davidson - 13.5" Chrome (Part No. 412-4003C)

412 Series Shock - 13.5" - Standard - Chrome - H-D

The Progressive Suspension 412 Series Shock for Harley Davidson motorcycles offers a reliable and cost-effective upgrade to enhance your bike's suspension performance. Designed specifically for Harley models, this shock features a simple yet durable construction that provides consistent ride quality. Its 13.5-inch length, measured from center of eyelet to center of eyelet, ensures compatibility with a wide range of Harley models, making it an excellent choice for riders seeking improved comfort and handling. The shock's chrome finish adds a classic visual appeal, complementing your motorcycle's aesthetic while providing corrosion resistance for long-lasting performance. The 412 Series incorporates a five-position cam-style spring preload adjuster, allowing you to fine-tune the ride according to your load and riding conditions, ensuring optimal comfort and stability. Some or all shocks listed are approved for street use; please refer to the latest certification for current compliance. The design allows for multiple style options, including full show-chrome or black covers, as well as chrome or black springs and end caps, enabling customization to match your bike’s style. When installing on '86-'15 XL models, modifications or spacers to the chain or belt guard may be necessary to achieve proper clearance. Slight variations in length—either longer or shorter than stock—can influence steering characteristics by subtly altering the head angle, providing quicker or slower steering responses accordingly. Heavy-duty applications are recommended if your bike operates near the maximum load rating most of the time. Before choosing shocks that differ from the OEM length, verify that wheel travel and clearance issues—such as swingarm contact with the exhaust, chain/belt guard, or tires—are adequately addressed to prevent interference and ensure safe operation. Built in the USA, the Progressive Suspension 412 Series Shock is a versatile upgrade that enhances ride quality, handling, and style for Harley Davidson enthusiasts seeking dependable suspension components.
