The Progressive Suspension 412 Series Shock is designed specifically for Harley-Davidson models, offering a simple yet durable upgrade to enhance your motorcycle's suspension performance. Constructed with quality materials and made in the USA, this shock absorber is engineered to provide a smoother ride and improved handling, especially under heavy load conditions. Its robust black finish adds a sleek appearance while ensuring long-lasting durability. The 412 Series features a five-position cam-style spring preload adjuster, allowing you to easily customize your ride for different terrains or personal preferences, ensuring optimal comfort and stability. Suitable for various Harley models, some shocks may require modifications such as spacers or adjustments to the chain or belt guard to ensure proper clearance, particularly on '86-'15 XL models. Installing a slightly longer or shorter shock than stock may influence the bike’s head angle, resulting in quicker or slower steering response, which can be beneficial depending on your riding style. Heavy-duty applications are recommended for bikes frequently operated near maximum load ratings, providing additional support and durability. Before installation, verify that your wheel travel can accommodate shocks of different lengths without causing clearance issues with the swingarm, exhaust, or tires. This shock is available in multiple styles, including full show-chrome or black covers, as well as chrome or black springs and end caps, allowing you to customize the aesthetic to match your bike’s look. Whether you prefer a traditional or modern appearance, this shock provides reliable performance and enhanced ride quality for aggressive or touring riding conditions.
