The Progressive Suspension 412 Series Shock, designed specifically for Harley-Davidson motorcycles, offers a reliable and cost-effective upgrade to your bike's suspension system. With its simple yet durable construction, this shock absorber enhances ride comfort and stability, making it suitable for a variety of riding conditions. The 12-inch length, measured from center-of-eyelet to center-of-eyelet, is compatible with a wide range of Harley models and can be adjusted to suit your riding style and load requirements. Its heavy-duty design ensures improved performance even under the most demanding conditions, especially for bikes operated near maximum load capacity frequently. The shock features a five-position cam-style spring preload adjuster, allowing riders to easily dial in the optimal ride height and firmness without the need for specialized tools. This adjustability ensures a tailored riding experience, whether you're cruising on highways or tackling rugged terrain. The shock is available in multiple finishes, including full show-chrome, black covers, chrome springs, and black springs and end caps, enabling customization to match your bike's aesthetic. Made in the USA, these shocks are approved for road use, but installation may require modifications, such as adjusting or spacing the chain or belt guard, especially on '86-'15 XL models, to ensure proper clearance. Slightly longer shocks may slightly alter the head angle, resulting in quicker steering, while shorter shocks can slow steering response. Heavy-duty applications are recommended for riders frequently operating at or near maximum load, providing enhanced durability under stress. Before installation, verify that your wheel travel and clearance space are sufficient to accommodate different shock lengths to prevent contact issues with the swingarm, exhaust, or tires. Properly installed, the Progressive Suspension 412 shocks can significantly improve your motorcycle's handling, comfort, and overall riding experience.
