Upgrade your Harley Dyna with the Progressive Suspension 412 Series Shock, designed for optimal performance and durability. This shock absorber features a simple yet robust construction that enhances your motorcycle's suspension system, providing a smoother ride and improved handling. Its cost-effective design makes it an excellent choice for riders seeking reliable suspension upgrades without excessive expense. The 412 series shock is equipped with a five-position cam-style spring preload adjuster, allowing you to easily fine-tune your ride for different loads and riding conditions, ensuring maximum comfort and stability.
Made in the USA, this shock is available in a sleek black finish that complements a variety of motorcycle aesthetics. The shock's center-to-center measurement ensures precise fitment, and it is suitable for a range of Harley models, including those from 1986 to 2015. When installing on '86-'15 XL models, modifications such as spacing the chain or belt guard may be necessary to achieve proper clearance. Additionally, selecting a shock that is slightly longer or shorter than the stock can subtly alter the head angle, affecting steering response — a longer shock typically results in quicker steering, while a shorter one may slow the turn-in.
Heavy-duty applications are recommended for bikes frequently operated near their maximum load rating, especially over 50% of the time. Before purchasing, confirm that the altered wheel travel from the new shocks won't cause clearance issues with components like the swingarm, axle, exhaust, or tire. Some or all shocks in this series are approved for road use, but it’s advisable to check the latest certification details to ensure compliance. The Progressive Suspension 412 Series Shock offers a versatile upgrade option with multiple style choices, including chrome or black covers, springs, and end caps, allowing you to customize your motorcycle's look and performance to your preferences.
