Designed specifically for Harley-Davidson FL models, the Progressive Suspension 412 Series Shock offers a reliable and cost-effective upgrade to your motorcycle's suspension system. Featuring a simple yet durable design, these shocks are built to enhance ride comfort and handling performance. The 412 shocks include a five-position cam-style spring preload adjuster, allowing riders to easily fine-tune their suspension settings to match riding preferences and load conditions. Made in the USA, these shocks are available with various styling options, including full show-chrome, black covers, chrome springs, and black springs with end caps, providing customization to match your bike's aesthetic.
Each shock measures from center of eyelet to center of eyelet, ensuring proper fitment for Harley models. When installing shocks on '86-'15 XL models, some modifications such as spacing the chain or belt guard may be necessary to ensure proper clearance. Slight variations in shock length compared to stock can influence steering behavior; longer shocks typically result in quicker steering, while shorter shocks may slow steering response. Heavy-duty applications are recommended for bikes often operated near their maximum load capacity, typically over 50% of the time.
Before choosing shocks that differ from OEM length, verify that your wheel travel can accommodate the change without clearance issues, such as contact between the swingarm, axle, exhaust, chain or belt guard, or tires. Proper installation and adjustment can improve ride quality, handling, and overall motorcycle stability, making the Progressive Suspension 412 Series a valuable upgrade for Harley owners seeking performance enhancements and customization options.
