Progressive Suspension 412 Series Shock for Harley Dyna - 11 inch Black

412 Series Shock - 11" - Standard - Black - Dyna

The Progressive Suspension 412 Series Shock (Part Number: 412-4037B) is engineered specifically for Harley Dyna models, offering an affordable upgrade to enhance your motorcycle's suspension performance. Featuring a simple yet durable design, these shocks are ideal for riders seeking improved ride comfort, handling, and stability. The 412 series includes a five-position cam-style spring preload adjuster, allowing you to easily customize the suspension setup to match your riding style and load conditions. This adjustability makes it straightforward to dial in your ride for smoother handling and better response on various road surfaces. All shocks are made in the USA and are measured center-to-center eyelet, ensuring consistent fitment and performance. The black cover option provides a sleek, understated look that complements the aesthetic of most Harley models. Some shocks listed may be approved for road use, but it's advisable to verify the latest certification for compliance. When installing on '86-'15 XL models, modifications such as spacers or adjustments to the chain or belt guard may be necessary for proper clearance. Slight variations in shock length can influence steering characteristics; a longer shock may provide quicker steering, while a shorter shock could result in slightly slower handling. Heavy-duty applications are recommended for bikes frequently operated near the maximum load rating, ensuring longevity and performance under demanding conditions. Before selecting shocks that differ from OEM length, confirm that your wheel travel can be adjusted without causing interference with components such as the swingarm, exhaust, or tires. Proper installation and compatibility are crucial to maintaining optimal motorcycle handling and safety.
