Progressive Suspension 412 Series Shock - 13 Inch Heavy Duty Chrome for Harley FL Models (Part #412-4077C)

The Progressive Suspension 412 Series Shock with a 13-inch length is engineered specifically for Harley-Davidson FL models, delivering improved suspension performance and rider comfort. Its durable design makes it a cost-effective upgrade for motorcycle enthusiasts seeking enhanced handling and ride quality. The shock features a simple yet robust construction, ideal for riders who demand reliable performance on the road. Made in the USA, this shock offers quality craftsmanship and durability, ensuring long-lasting service under demanding conditions.
Equipped with a five-position cam-style spring preload adjuster, this shock allows you to easily fine-tune your ride to match your riding style and load conditions. Whether you're carrying a passenger or gear, the preload can be adjusted to optimize comfort and handling. The chrome finish adds a sleek aesthetic to your motorcycle, complementing various custom styles. Some or all shocks listed are approved for road use; always refer to the latest certification for current compliance. The shock's center-to-center eyelet measurement ensures compatibility with your Harley model, but minor modifications to the chain or belt guard may be necessary on '86-'15 XL models to ensure proper clearance.
The 412-4077C shock is slightly longer than stock, which can slightly alter the head angle and provide quicker steering response. Conversely, a slightly shorter shock can offer a slower steering feel. For bikes operating near maximum load ratings over 50% of the time, Heavy Duty applications are recommended. When selecting shocks, confirm that your wheel travel can accommodate the change in length without causing interference with components such as the swingarm, exhaust, or tires. The available style options include full show-chrome, black covers, chrome springs, or black springs and end caps, allowing you to customize the look of your motorcycle.
Overall, the Progressive Suspension 412 Series Shock is a versatile upgrade designed to enhance your Harley’s ride quality, handling, and aesthetic appeal, making it suitable for both daily commuting and spirited riding adventures.
