Progressive Suspension 412 Series Shock for Harley FXD 14-Inch Black, Part 412-4085B
Regular price $379.95 USD
Category:
Enhance your Harley Davidson FXD with the Progressive Suspension 412 Series Shock, designed for reliable performance and easy adjustment. This 14-inch shock features a simple, durable design that offers a cost-effective upgrade to your motorcycle's suspension system. Its robust construction ensures longevity and consistent handling, making it suitable for riders seeking improved comfort and stability on the road. The 412 Series shock includes a five-position cam-style spring preload adjuster, allowing you to effortlessly customize ride height and firmness to match your riding style and load conditions. Whether you're navigating city streets or long highway stretches, this shock helps you achieve optimal ride quality with minimal effort.
Made in the USA, the Progressive Suspension 412 Series shock is engineered with versatility in mind. It is available with various style options, including full show-chrome or black covers, and chrome or black springs and end caps, enabling you to match your bike's aesthetic. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility with your specific model. When installing on '86-'15 XL models, modifications to the chain or belt guard may be necessary to provide adequate clearance. It's important to verify that your wheel travel can accommodate shocks of different lengths without causing contact issues with the exhaust, swingarm, or tire.
Adjusting the shock length slightly longer than stock can result in a minor change to the head angle, providing quicker steering response, while a shorter shock may slow steering for a more relaxed ride. For bikes operated near maximum load capacity over 50% of the time, Heavy Duty applications are recommended to withstand increased stresses. Proper installation and consideration of clearance issues will ensure optimal performance and safety, making the Progressive Suspension 412 Series Shock an excellent choice for riders seeking dependable suspension upgrades.
