Progressive Suspension 412 Series Shock - 13 Inch Heavy Duty Black for Harley-Davidson - Model 412-4008B

The Progressive Suspension 412 Series Shock, part number 412-4008B, is engineered specifically for Harley-Davidson models, offering a reliable and cost-effective upgrade to enhance your motorcycle's suspension performance. Crafted with durability in mind, these shocks feature a simple yet robust design that ensures long-lasting operation under various riding conditions. The black finish provides a sleek, modern look, complementing your motorcycle's aesthetics while delivering essential performance benefits.

The 412 Series shocks include a five-position cam-style spring load preload adjuster, allowing riders to easily fine-tune their ride for a customized experience. Whether you prefer a softer or firmer suspension setting, this adjuster makes it straightforward to dial in your preferred ride height and comfort level. While some models are approved for road use, it is recommended to verify the current certification to ensure compliance and safety on public roads.

Designed to fit a range of Harley models, these shocks are measured from center-of-eyelet to center-of-eyelet, ensuring proper fitment. Installing shocks on '86-'15 XL models may require modifications or spacing of the chain or belt guard to maintain adequate clearance. Slight variations in shock length can influence steering response; a longer shock may provide quicker steering, while a shorter shock may result in slower handling. Heavy-duty applications are suggested for bikes frequently operated near maximum load ratings, typically over 50%. Before installation, confirm that altered wheel travel will not cause clearance issues with components such as the swingarm, exhaust, or tires, especially when choosing shocks that differ from stock length.

These shocks are made in the USA, ensuring quality craftsmanship and reliability. Multiple style options are available, including full show-chrome or black covers, as well as chrome or black springs and end caps, allowing customization to match your motorcycle's look. Whether you're seeking improved ride quality or a visual upgrade, the Progressive Suspension 412 Series Shock provides a practical and effective solution for Harley owners seeking to enhance their motorcycle's suspension performance.
