The Progressive Suspension 412 Series Shock (Part Number: 412-4068B) offers a reliable and cost-effective upgrade for Harley-Davidson motorcycles, designed specifically to enhance suspension performance. With a simple yet durable construction, these shocks provide a substantial improvement in ride quality and handling. The 12-inch length and robust build make them a popular choice for riders seeking a balance of comfort and performance. Made in the USA, the shocks feature a black finish that complements a variety of custom styles and motorcycle aesthetics.
Equipped with a five-position cam-style spring load preload adjuster, these shocks allow riders to easily dial in their preferred ride height and firmness. This adjustability ensures optimal comfort and stability regardless of load or riding conditions. Some models are approved for road use, and it’s recommended to consult the latest certification to confirm compliance. The shocks are available in multiple style options, including full show-chrome or black covers, as well as chrome or black springs and end caps, providing versatile customization choices.
When installing these shocks on Harley models from 1986 to 2015 XL, it may be necessary to modify or space the chain or belt guard to ensure proper clearance. Slight variations in shock length—either longer or shorter than stock—can impact the motorcycle’s head angle, influencing steering response. A slightly longer shock can provide quicker steering, while a shorter one may result in slower handling. For bikes operated under heavy loads near the manufacturer’s maximum capacity, Heavy Duty applications are recommended to withstand increased stress and ensure durability. Before swapping shocks with different lengths than OEM, confirm that wheel travel and clearance around the swingarm, axle, exhaust, and tires are maintained to prevent contact issues and ensure safe operation.
Designed for versatility and performance, the Progressive Suspension 412 Series Shock is an excellent choice for riders seeking improved ride quality, adjustable settings, and a sleek appearance to complement their Harley-Davidson motorcycle.
