Progressive Suspension 412 Series Shock for Harley FXD - 13-1/2 Inch Heavy Duty Black - Part #412-4084B

412 Series Shock - 13-1/2" - Heavy Duty - Black - FXD

The Progressive Suspension 412 Series Shock is specifically engineered for Harley-Davidson FXD models, offering a simple yet durable upgrade to your motorcycle's suspension system. Crafted with a focus on performance and reliability, these shocks feature a five-position cam-style spring preload adjuster, allowing riders to easily customize ride firmness for different riding conditions or preferences. Whether you seek a softer ride or more firm support, this adjustment system provides precise control to enhance your riding experience.
Constructed in the USA, the 412 shocks are available in multiple styles, including full show-chrome or black covers, and either chrome or black springs and end caps, enabling customization to match your bike’s aesthetic. These shocks are measured from center-of-eyelet to center-of-eyelet, ensuring proper fitment on compatible Harley models. When installing on '86-'15 XL models, some modifications or spacing of the chain or belt guard may be necessary to ensure proper clearance and avoid contact with other components.
Adjusting the length of the shocks can influence steering dynamics; a slightly longer shock may result in a quicker steering response by subtly changing the head angle, while a shorter shock may offer a more relaxed steering feel. Heavy Duty applications are recommended for bikes regularly operating near the maximum load capacity, providing additional strength and durability under demanding conditions. Before installation, verify that the wheel travel can accommodate any length modifications without causing clearance issues with the swingarm, exhaust, or other parts of the motorcycle’s chassis, including the chain or belt guard. This ensures optimal performance and safety during your rides.
Designed for professional-grade durability and performance, the PROGRESSIVE SUSPENSION 412 Series Shock is an ideal upgrade for Harley enthusiasts seeking improved ride quality and handling. Whether you ride on city streets or rough terrains, these shocks are built to withstand demanding conditions, ensuring a smooth and controlled ride over various surfaces.
