412 Series Shock - 14.25" - Standard - Chrome - H-D
The Progressive Suspension 412 Series Shock is designed specifically for Harley-Davidson models, offering a simple yet durable upgrade to your motorcycle's suspension system. With a length of approximately 14.25 inches, these shocks provide improved ride comfort and handling, making them an excellent choice for riders seeking performance enhancements without complicated installation processes. The robust construction ensures longevity, while the chrome finish adds a sleek, classic look to your bike's rear end. These shocks are suitable for various Harley models, including the XL series from 1986 to 2015, and are made in the USA, reflecting quality craftsmanship and reliability.
The 412 shocks feature a five-position cam-style spring load preload adjuster, allowing riders to easily customize their ride stiffness and comfort levels. This adjustability makes it simple to dial in the perfect setup for different loads or riding conditions. Some or all of the shocks listed are approved for road use, though it is recommended to verify current certification. The shocks are measured from center of eyelet to center of eyelet, ensuring compatibility with your motorcycle’s existing mounting points.
Installation may require minor modifications, such as adjusting or spacing the chain or belt guard on '86-'15 XL models, to ensure proper clearance. Slight variations in shock length—either longer or shorter than stock—can influence steering characteristics by altering the head angle, resulting in quicker or slower steering responses. Heavy-duty applications are ideal for bikes operated near maximum load ratings over 50% of the time, providing additional durability under demanding conditions. Before choosing shocks that differ from the OEM length, confirm that your wheel travel and clearance are sufficient to prevent contact issues with components like the swingarm, axle, exhaust, or tires, ensuring safe and reliable performance.
Available in multiple style options, including full show-chrome or black covers, and chrome or black springs and end caps, the Progressive Suspension 412 Series shocks combine style and functionality. Their straightforward design and high-quality materials make them a cost-effective upgrade for enhancing your Harley-Davidson’s suspension performance and ride quality.
