Progressive Suspension 412 Series Heavy Duty Shock Absorber for Harley - 12.5 inch Black 412-4060B

The Progressive Suspension 412 Series Shock (Part Number: 412-4060B) is engineered specifically for Harley-Davidson models, offering a simple yet durable upgrade to enhance your motorcycle's suspension performance. Crafted in the USA, this shock features a five-position cam-style spring preload adjuster, allowing riders to easily dial in their preferred ride stiffness for optimal comfort and handling. Its versatile design includes options for full show-chrome or black covers, along with chrome or black springs and end caps, providing customization to match your bike's aesthetic. The 12.5-inch length is measured center-to-center of the eyelets, ensuring precise fitment and compatibility with various Harley models. This shock is suitable for both street and heavy-duty applications, making it an excellent choice for riders operating at or near the maximum load capacity most of the time. It is important to confirm that wheel travel and clearance issues, such as swingarm or tire contact, are addressed prior to installation, especially when selecting shocks with lengths different from OEM. Slight modifications, like adjusting or spacing the chain or belt guard, may be necessary on certain models, such as those from 1986 to 2015 XL series. Longer shocks can provide quicker steering by altering the head angle, while shorter shocks may result in a slower steering response. Overall, the Progressive Suspension 412 Series Shock offers a cost-effective, high-quality upgrade capable of improving ride quality, handling, and load capacity for Harley riders seeking dependable performance.
