Progressive Suspension 412 Series Shock - 12 Inch Standard Chrome for Harley FLH/T Models

The Progressive Suspension 412 Series Shock, part number 412-4079C, is designed specifically for Harley Davidson FLH and T models, offering a reliable upgrade to enhance your motorcycle's suspension performance. This 12-inch shock features a simple yet durable design that provides a cost-effective improvement for riders seeking better ride quality and handling. The shock's construction includes a chrome cover that complements the classic Harley aesthetic, with available options for black covers, springs, and end caps to match your custom preferences. Made in the USA, these shocks are built to meet high standards of quality and durability, ensuring long-lasting performance on the road.

Equipped with a five-position cam-style spring preload adjuster, the 412 series allows you to easily dial in your ride to match your weight and riding style. Whether you're carrying a passenger or hauling gear, this feature provides versatile customization for optimal comfort and control. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility and straightforward installation. When installing on '86-'15 XL models, some modifications such as spacing the chain or belt guard may be necessary to ensure proper clearance and avoid contact with other components.

The design of these shocks can influence the steering response—slightly longer shocks may result in a quicker steering feel, while slightly shorter shocks might produce a slower turn-in. Heavy-duty applications are recommended for bikes that operate near their maximum load capacity more than half of the time, providing added strength and stability under demanding conditions. Before selecting shocks that differ from the stock length, verify that your wheel travel can accommodate the change without causing interference with the exhaust, swingarm, axle, chain or belt guard, or tire contact. This ensures your motorcycle maintains safe and effective operation while benefiting from improved suspension performance.
