Progressive Suspension 412 Series Shock - 12 inch Heavy Duty Black for Harley FL Models (Part #412-4080B)

The Progressive Suspension 412 Series Shock is designed specifically for Harley FL models, offering a practical and durable upgrade to your motorcycle's suspension system. With a 12-inch length, this shock provides improved ride quality and handling, especially under heavy loads. Its simple yet robust design ensures longevity and reliable performance on the road. The shock features a five-position cam-style spring load preload adjuster, allowing riders to easily customize the ride firmness to suit personal preferences and riding conditions. Made in the USA, this shock combines quality craftsmanship with affordability, making it an excellent choice for both casual riders and enthusiasts seeking a performance boost.

Available in multiple styles, including full show-chrome or black covers, and with either chrome or black springs and end caps, the 412 Series Shock offers versatility to match your motorcycle's aesthetic. It is important to note that some shocks listed are approved for road use; always refer to the most recent certification for compliance. When installing shocks on '86-'15 XL models, modifications or spacers to the chain or belt guard may be necessary to ensure proper clearance. Slight variations in shock length can affect steering dynamics; a longer shock may lead to quicker steering, while a shorter shock might result in slower handling. Heavy-duty applications are recommended for bikes frequently operated near the maximum load capacity, providing extra strength and durability.

Before selecting shocks different from the OEM length, verify that your wheel travel can accommodate the change without causing clearance issues such as contact with the swingarm, exhaust, or tire. Proper installation ensures optimal performance and safety, enhancing both comfort and control during your ride.
