Progressive Suspension 412 Series Shock - 11 Inch Heavy Duty Black for Harley Dyna 412-4045B

Designed specifically for Harley Dyna models, the Progressive Suspension 412 Series Shock offers a reliable and cost-effective upgrade to your motorcycle's suspension system. Constructed with durable materials, these shocks feature a simple yet robust design that enhances ride comfort and handling. The five-position cam-style spring preload adjuster allows riders to easily fine-tune their suspension for personalized riding preferences and varying load conditions, ensuring optimal performance in diverse riding scenarios. Made in the USA, these shocks are built to high standards of quality and craftsmanship, providing long-lasting reliability for demanding riders.
Installation considerations include potential modifications to the chain or belt guard on 1986-2015 XL models to ensure proper clearance. The shocks are measured center-of-eyelet to center-of-eyelet, allowing for accurate compatibility checks with your motorcycle. Slight variations in shock length can affect steering characteristics: a longer shock may result in quicker steering and a slight change in head angle, while a shorter shock might slow steering response. These shocks are recommended for heavy-duty applications, especially when the motorcycle is operated near its maximum load capacity over 50% of the time. When selecting shocks, verify that wheel travel and clearance issues are addressed to prevent contact with exhaust, swingarm, axle, or tires, especially when considering non-OEM lengths. The 412-4045B model provides a versatile upgrade for riders seeking improved suspension performance, durability, and customization options with available style variations such as chrome or black covers, springs, and end caps.
