Progressive Suspension 412 Series Shock - 12 Inch Heavy Duty Black for Harley Dyna Models 412-4036B

The Progressive Suspension 412 Series Shock is specifically engineered for Harley Dyna models, offering a cost-effective upgrade to improve your motorcycle's suspension performance. Its simple yet durable design ensures long-lasting reliability while enhancing ride comfort and handling. Made in the USA, this shock features a five-position cam-style spring preload adjuster for easy customization to suit your riding preferences and load requirements. Whether you're tackling daily commuting or spirited riding, this shock provides the versatility needed for various conditions.
Designed with multiple styling options, the 412 Series includes full show-chrome or black covers, along with chrome or black springs and end caps, allowing you to customize the look of your bike. All shocks are measured from center of eyelet to center of eyelet, ensuring compatibility and proper fitment. When installing on '86-'15 XL models, some modifications or spacers may be necessary for the chain or belt guard to ensure proper clearance. A slightly longer shock may subtly alter the head angle, resulting in quicker steering response, while a shorter shock can provide a slightly slower steering feel, both contributing to handling preferences.
Heavy-duty applications are recommended for bikes frequently operating at or near maximum load ratings, ensuring durability and safety under demanding conditions. Before purchasing or installing shocks that differ from OEM length, verify that wheel travel and clearance are adequate to prevent contact with exhaust, swingarm, axle, chain or belt guard, and tires. This ensures optimal performance and safety for your Harley Dyna motorcycle, making the Progressive Suspension 412 Series Shock a reliable choice for enhancing ride quality and handling.
