Upgrade your Harley-Davidson with the Progressive Suspension 412 Series Shock, designed to enhance your motorcycle's suspension performance and riding comfort. Constructed specifically for Harley models, these shocks feature a simple yet durable design that offers a cost-effective way to improve handling and ride quality. The 412's five-position cam-style spring preload adjuster allows riders to easily dial in the desired suspension stiffness, accommodating various loads and riding styles for a customized ride experience. Whether you're cruising on highways or tackling uneven terrains, this shock provides reliable performance and ease of adjustment.
Made in the USA, the 412 Series Shock is available in multiple style options, including full show-chrome or black covers, with either chrome or black springs and end caps. This versatility ensures that your motorcycle maintains a sleek appearance while benefiting from superior suspension components. Please note that some shocks may be approved for road use, but it is recommended to verify current certification status. When installing on 1986 to 2015 XL models, modifications or spacers for the chain or belt guard might be necessary to ensure proper clearance. Additionally, slightly longer shocks can provide quicker steering by altering the head angle, while shorter shocks may slow steering response, allowing riders to tailor handling to their preferences.
Heavy duty applications are recommended for bikes operated near or at maximum load ratings over 50% of the time, ensuring durability and performance under demanding conditions. Before selecting shocks with lengths different from OEM specifications, confirm that wheel travel and clearance issues such as swingarm or axle contact with exhaust, chain or belt guard, or tires are addressed. Proper installation and compatibility are essential for optimal performance and safety. The Progressive Suspension 412-4066C Shock is an excellent investment for riders seeking reliable, adjustable suspension upgrades that improve ride quality, handling, and aesthetics.
