Upgrade your Harley-Davidson FL model with the Progressive Suspension 412 Series Shock, designed specifically for optimal performance and durability. This 12.5-inch shock features a simple yet robust design that provides a cost-effective way to enhance your motorcycle's suspension system. The shock's heavy-duty construction makes it suitable for riders who frequently operate at or near the maximum load capacity, ensuring stability and control under demanding conditions.
The 412 Series Shock is equipped with a five-position cam-style spring preload adjuster, allowing riders to easily dial in the ride height and suspension firmness for a personalized riding experience. Whether you prefer a softer ride for cruising or a stiffer setup for aggressive handling, this feature provides versatile adjustability. Made in the USA, the shock combines quality craftsmanship with reliable performance, ensuring longevity and consistent operation.
Compatibility and installation are straightforward, but some models, particularly those from 1986 to 2015 XL, may require modifications such as spacing the chain or belt guard for proper clearance. The shock's slight variation from stock length can influence steering dynamics; a longer shock may provide quicker steering, while a shorter one may result in slightly slower handling. It’s important to verify that your wheel travel can accommodate length changes without causing contact issues with the swingarm, exhaust, or other components.
Available with options like full show-chrome or black covers, as well as chrome or black springs and end caps, this shock offers both functional and aesthetic customization. Some models are approved for road use, but it’s recommended to consult the latest certification to ensure compliance. The Progressive Suspension 412 Series Shock is a reliable upgrade for riders seeking enhanced suspension performance, improved handling, and a tailored riding experience.
