Progressive Suspension 412 Series Shock - 12 Inch, Black Finish for Harley FLH/T Models (Part #412-4079B)

The Progressive Suspension 412 Series Shock, model 412-4079B, is engineered to enhance the suspension performance of Harley FLH and T models with a 12-inch length. Crafted with durability in mind, these shocks feature a simple yet robust design that offers a cost-effective upgrade over stock components. The shocks are made in the USA and incorporate a five-position cam-style spring preload adjuster, allowing riders to easily customize ride stiffness for optimal comfort and handling. Their versatile design includes options with full show-chrome or black covers, as well as chrome or black springs and end caps, providing aesthetic choices to match your motorcycle's style.

These shocks are specifically designed to improve ride quality by subtly altering the motorcycle's geometry. Slightly longer shocks can provide quicker steering, while shorter shocks may result in a more relaxed steering feel. The installation process may require modifications, such as adjusting or spacing the chain or belt guard, especially on '86-'15 XL models, to ensure proper clearance. It is important to verify wheel travel and clearance before installation to prevent contact issues with the swingarm, exhaust, or tires. Heavy duty applications are recommended for bikes frequently operated near maximum load capacity, ensuring longevity and performance under demanding conditions.

Each shock is measured from center-of-eyelet to center-of-eyelet, ensuring precise fitment and compatibility. The shocks are approved for road use, with certification available for the latest compliance standards. Whether you're seeking a performance upgrade, a visual enhancement, or both, the Progressive Suspension 412 Series Shock offers a reliable, adjustable, and stylish solution to improve your Harley-Davidson's handling and ride quality.
