The Progressive Suspension 412 Series Shock, part number 412-4060B, is engineered specifically for Harley-Davidson models, delivering a reliable upgrade for improved suspension performance. Featuring a simple yet durable design, these shocks are a cost-effective solution for riders seeking enhanced comfort and handling. The five-position cam style spring preload adjuster allows for quick and precise tuning of your ride, accommodating various load conditions and rider preferences. Made in the USA, these shocks are available with options such as full show-chrome or black covers, along with chrome or black springs and end caps, allowing you to customize the look to match your motorcycle’s style.
Designed with versatility in mind, the shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility across a range of Harley models. When installing on '86-'15 XL models, some modifications or spacers may be necessary to ensure proper clearance with the chain or belt guard. Slight variations in length—either longer or shorter than stock—can influence steering characteristics, with longer shocks providing quicker steering and shorter shocks offering a more relaxed feel. The heavy-duty application is recommended for bikes regularly operating near the maximum load rating, ensuring durability under demanding conditions.
Before selecting shocks that differ from OEM length, it’s important to verify that your wheel travel and clearance are adequate to prevent contact with exhaust, swingarm, axle, or tires. Some shocks listed are approved for road use; always refer to the latest certification for compliance. Whether you're looking to improve ride quality, handling, or aesthetics, the Progressive Suspension 412 Series Shock offers a versatile, high-quality upgrade that enhances your Harley-Davidson’s performance and style.
