Progressive Suspension 412 Series Shock - 12.5 Inch - Chrome - Harley-Davidson 412-4001C

412 Series Shock - 12.5" - Standard - Chrome - H-D

The Progressive Suspension 412 Series Shock (Part Number: 412-4001C) is engineered specifically for Harley-Davidson models, offering a straightforward and durable upgrade to enhance your motorcycle's suspension performance. Featuring a five-position cam-style spring preload adjuster, these shocks allow riders to easily fine-tune their ride for optimal comfort and handling on various road conditions. The 12.5-inch length provides a balanced ride height, contributing to improved stability and control during highway cruising or spirited riding.
Constructed in the USA, these shocks are available with multiple style options, including full show-chrome or black covers, as well as chrome or black springs and end caps, allowing riders to match their bike's aesthetic preferences. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring precise fitment. Some models are approved for road use; however, it is advisable to consult recent certification documents to confirm legal compliance in your area. When installing on '86-'15 XL models, modifications such as spacing the chain or belt guard may be necessary to ensure proper clearance.
Choosing a slightly longer shock than stock can result in a subtle change in head angle, offering quicker steering response, whereas a slightly shorter shock may slow steering for more stability. Heavy-duty applications are recommended for bikes frequently operated near maximum load capacity, typically over 50% of the time. Before installing shocks that differ from OEM length, verify that your wheel travel can accommodate the change without causing contact issues with the swingarm, axle, exhaust, chain or belt guard, or tires. This ensures safe and effective suspension performance tailored to your riding style and bike specifications.
