Progressive Suspension 412 Series Shock for Harley - 11.5 Inch Black (Part #412-4063B)

The Progressive Suspension 412 Series Shock, model 412-4063B, is engineered specifically for Harley-Davidson models, offering a simple yet durable upgrade to enhance your motorcycle's suspension performance. Designed with a five-position cam-style spring load preload adjuster, this shock allows riders to easily customize ride height and firmness for optimal comfort and handling. Its straightforward design makes it a cost-effective solution for improving ride quality without sacrificing reliability or style.
Constructed in the USA, the 412 Series Shock features a sleek black finish that complements a variety of motorcycle aesthetics. These shocks are available in multiple style options, including full show-chrome or black covers, and chrome or black springs and end caps, enabling customization to match your bike's look. All shocks are measured from center of eyelet to center of eyelet, ensuring proper fitment and compatibility. When installing on 1986-2015 XL models, some modifications to the chain or belt guard may be necessary for clearance, so it's important to verify compatibility before installation.
The 11.5-inch length provides a slight change in ride height, which can influence steering characteristics—longer shocks may offer quicker steering, while shorter ones may slow the steering response. Heavy-duty applications are recommended for bikes frequently operated near the maximum load rating, typically over 50% of the time. Prior to purchasing, confirm that your wheel travel can accommodate length modifications without causing interference with the swingarm, exhaust, chain or belt guard, or tires. This shock is approved for road use, aligning with current safety and performance standards, making it a reliable choice for riders seeking to improve comfort and handling on their Harley-Davidson motorcycle.
