The Progressive Suspension 412 Series Shock is specifically designed for Harley Davidson Dyna models, providing a reliable upgrade to enhance your motorcycle's suspension performance. Featuring a simple yet durable construction, these shocks are an economical way to improve ride comfort and handling. The black finish adds a sleek look to your bike while maintaining durability for long-term use. Crafted with quality materials in the USA, these shocks are built to withstand demanding riding conditions and offer consistent performance.
The 412 Series Shock includes a five-position cam-style spring preload adjuster, allowing riders to easily customize their ride based on load and terrain. This feature enables quick and precise tuning without the need for special tools, ensuring optimal comfort and control. Designed to be versatile, some or all shocks listed are approved for road use, but it's essential to verify the current certification for your specific application. The shocks are measured from center of eyelet to center of eyelet, ensuring compatibility with a range of Harley Dyna models.
Installation on 1986-2015 XL models may require modifications or spacing of the chain or belt guard to ensure proper clearance. Slightly longer shocks than stock can influence the head angle, resulting in quicker steering, whereas shorter shocks may lead to slightly slower steering. Heavy Duty applications are recommended for bikes frequently operated near maximum load capacity, providing additional strength and durability for demanding riding conditions.
Before selecting shocks that differ from OEM length, confirm that your wheel travel can be adjusted without causing clearance issues such as contact with the exhaust, swingarm, or tires. Proper installation and correct sizing are essential to maintaining safety and performance. With multiple style options available, including chrome or black covers and springs, you can customize the look of your ride while benefiting from improved suspension characteristics. The Progressive Suspension 412 Series Shock is a trusted choice for Harley Dyna riders seeking a blend of performance, durability, and style.
