412 Series Shock - 11" - Standard - Black - Dyna
The Progressive Suspension 412 Series Shock is specifically designed for Harley Dyna models, offering a simple yet durable upgrade to enhance your motorcycle's suspension performance. Crafted in the USA, this shock absorber features a robust construction with a sleek black finish that complements various bike styles and aesthetics. Its design includes a five-position cam style spring preload adjuster, allowing you to easily dial in your ride for optimal comfort and handling across different riding conditions. This adjustability provides a customized riding experience, whether you're cruising on city streets or tackling rougher terrain. The 11-inch length is measured from center of eyelet to center of eyelet, ensuring compatibility with a range of Harley Dyna models and configurations.
The Progressive 412 shock is suitable for both street and light off-road applications, and some configurations are approved for road use, with certification details available upon request. When installing on '86-'15 XL models, you may need to modify or space the chain or belt guard to ensure proper clearance. Slight modifications to the shock length can influence the bike's steering characteristics; a longer shock might slightly quicken steering response, while a shorter one could slow it down. Heavier duty applications are recommended for bikes operated near or at maximum load capacity more than half the time, providing enhanced durability and performance under demanding conditions.
Before selecting shocks that differ from the OEM length, verify that your motorcycle's wheel travel and clearance are sufficient to prevent contact issues with the swingarm, exhaust, chain or belt guard, or tires. This ensures safe and reliable operation while optimizing ride quality. With multiple style options available, including full show-chrome or black covers, as well as chrome or black springs and end caps, you can customize the look of your bike while benefiting from improved suspension performance with the Progressive Suspension 412 Series Shock.
