Progressive Suspension 412 Series Shock - 12 Inch Standard Black for Harley-Davidson Models 412-4051B

412 Series Shock - 12" - Standard - Black - H-D

The Progressive Suspension 412 Series Shock is engineered specifically for Harley-Davidson models, offering a simple yet durable upgrade to enhance your motorcycle's suspension performance. Designed with efficiency in mind, this 12-inch shock features a robust construction that provides reliable performance on the road. Its straightforward design makes installation easier, allowing riders to improve ride comfort and handling without extensive modifications. The shock's compatibility with most Harley models ensures a versatile fit, making it a popular choice among enthusiasts looking for a cost-effective suspension upgrade.
Equipped with a five-position cam-style spring preload adjuster, riders can easily fine-tune their ride to match riding conditions or personal preference. This feature allows for quick adjustments to achieve the desired ride height and firmness, whether you're tackling rough terrain or cruising smoothly. The shocks are available in multiple finishes, including full show-chrome or black covers, with chrome or black springs and end caps, allowing for customization to match your bike's style. Made in the USA, these shocks are built to high standards of quality and durability, ensuring long-lasting performance.
When installing these shocks on '86-'15 XL models, some modifications to the chain or belt guard may be necessary to ensure proper clearance. Slightly longer or shorter shocks compared to stock can affect the head angle, influencing steering response—quicker with longer shocks and slightly slower with shorter ones. For heavy-duty applications, where the bike is frequently operated near maximum load, it is recommended to use shocks rated for heavy-duty use to maintain optimal performance. Riders should verify that wheel travel and clearance are adequate when selecting shocks of different lengths to prevent contact issues with exhaust, chain/belt guards, or tires. Overall, the Progressive Suspension 412 Series Shock provides a reliable, adjustable, and stylish upgrade for Harley-Davidson enthusiasts seeking improved ride quality and handling.
All shocks are measured from center of eyelet to center of eyelet, ensuring consistent sizing and fitment for your motorcycle.
