Progressive Suspension 412 Series Shock for Harley FXD - 13 Inch Black - Model 412-4083B

412 Series Shock - 13" - Standard - Black - FXD

The Progressive Suspension 412 Series Shock for Harley FXD models offers a reliable upgrade to your motorcycle's suspension system, combining durability with enhanced performance. Crafted specifically for Harley-Davidson motorcycles, these shocks feature a simple yet robust design that provides an affordable way to improve ride quality and handling. The five-position cam-style spring load preload adjuster allows riders to easily dial in their preferred ride stiffness, accommodating different loads and riding conditions for a customized experience.

Constructed in the USA, the 412 Series shocks are available in various styles, including full show-chrome, black covers, chrome springs, or black springs and end caps, offering both aesthetic options and functional durability. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility with Harley FXD models from 1986 to 2015. When installing these shocks on '86-'15 XL models, it may be necessary to modify or add spacers to the chain or belt guard to ensure proper clearance without interference. A slightly longer shock may result in a modest change to the head angle, providing quicker steering, while a shorter shock could slow steering slightly, allowing for tailored handling preferences.

Heavy-duty applications are recommended for bikes frequently operated near the maximum load capacity, ensuring longevity and consistent performance under demanding conditions. Before selecting shocks that differ from OEM specifications, confirm that your wheel travel allows for modifications without causing clearance issues such as contact with the exhaust, swingarm, axle, or tire. Proper installation and adjustment will optimize your motorcycle's handling and comfort, making the Progressive Suspension 412 Series an excellent choice for riders seeking an upgrade that balances performance, style, and value.
