Progressive Suspension 412 Series Shock - 12.5 Inch Heavy Duty Chrome for Harley-Davidson 412-4019C

The Progressive Suspension 412 Series Shock is designed specifically for Harley-Davidson models, offering a simple, durable, and cost-effective upgrade to your motorcycle's suspension system. With a 12.5-inch length, these shocks are engineered to improve ride quality and handling, whether you're cruising on the highway or tackling rougher terrain. The heavy-duty construction ensures reliable performance under demanding riding conditions, making them suitable for riders who frequently operate at or near their bike's maximum load capacity.
Features include a five-position cam-style spring preload adjuster, allowing you to easily fine-tune your ride for comfort or performance. This adjuster provides precise control over spring tension, enabling quick adjustments to suit different loads or riding styles. The shocks are available in multiple style options, such as full show-chrome or black covers, along with chrome or black springs and end caps, allowing you to customize the look of your motorcycle.
All shocks are measured center-of-eyelet to center-of-eyelet, ensuring proper fitment for Harley models from 1986 to 2015. When installing these shocks on '86-'15 XL models, it's important to verify that modifications or spacers are used as needed to provide adequate clearance for the chain or belt guard. Slight variations in length, either longer or shorter than stock, can influence steering characteristics by altering the head angle—longer shocks may provide quicker steering, while shorter ones may slow steering for a different ride feel. Proper wheel travel clearance should be confirmed before installation to prevent contact issues with the swingarm, exhaust, or tires.
Made in the USA, the PROGRESSIVE SUSPENSION 412 Series Shock is a reliable choice for riders seeking improved suspension performance and a customized appearance, with the assurance of quality craftsmanship and engineering that meets industry standards.
