The PROGRESSIVE SUSPENSION 412 Series Shock is engineered specifically for Harley Dyna models, offering a straightforward and durable upgrade to enhance your motorcycle's suspension performance. Its robust design ensures longevity and reliable handling, making it a cost-effective solution for riders seeking improved ride quality. The shock features a five-position cam-style spring preload adjuster, allowing you to easily fine-tune your ride for comfort and handling preferences, whether you're cruising or riding aggressively.
Constructed in the USA, these shocks are available with various style options, including full show-chrome or black covers, as well as chrome or black springs and end caps, so you can customize your bike's appearance to match your style. The shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility and consistent performance.
When installing on '86-'15 XL models, some modifications to the chain or belt guard may be necessary to ensure proper clearance, especially if choosing shocks that differ in length from stock. Slightly longer shocks can provide a subtle change in head angle, resulting in quicker steering, while shorter shocks may slow steering response. Heavy-duty applications are recommended for bikes operated near or at the maximum load capacity over 50% of the time, ensuring durability under demanding conditions.
Before installing shocks that differ from OEM length, verify that wheel travel and clearance are sufficient to prevent contact issues with the swingarm, exhaust, chain/belt guard, or tires. Proper assessment ensures optimal performance and safety, making the PROGRESSIVE SUSPENSION 412 Series Shock a smart upgrade for your Harley Dyna motorcycle.
