Progressive Suspension 412 Series Shock for Harley-Davidson, 12.5 inch, Chrome – Model 412-4007C

The Progressive Suspension 412 Series Shock is engineered specifically for Harley-Davidson models, providing a reliable and cost-effective upgrade to your motorcycle's suspension system. Featuring a simple yet durable design, this shock absorber enhances ride comfort and handling while maintaining an attractive appearance with a full chrome finish. The 12.5-inch length offers a balanced stance, contributing to improved ride quality and stability.
Designed with a five-position cam-style spring preload adjuster, riders can easily customize the suspension to match their riding style and load conditions. Whether you prefer a softer ride or a firmer feel, this feature allows precise tuning without the need for special tools. It is important to note that some or all shocks listed are approved for road use, but you should verify the latest certification to ensure compliance with local regulations.
Constructed in the USA, these shocks are built to meet high-quality standards and are suitable for heavy-duty applications, especially when operating near maximum load ratings. The shocks are measured center-of-eyelet to center-of-eyelet, ensuring compatibility with Harley models from 1986 to 2015 XL series. When installing on certain models, like the '86-'15 XL, modifications such as spacing the chain or belt guard may be necessary to ensure proper clearance.
The slight variation in length—either longer or shorter than stock—can subtly influence handling characteristics by altering the head angle, resulting in quicker or slower steering. It is crucial to confirm that your wheel travel can accommodate these changes without causing clearance issues or contact with exhaust, swingarm, axle, or tires. Proper installation and adjustment will maximize ride quality, safety, and performance for your Harley-Davidson motorcycle.
