Progressive Suspension 412 Series Shock - 11 Inch Standard Black for Harley-Davidson 412-4005B

The Progressive Suspension 412 Series Shock, designed specifically for Harley-Davidson models, offers a simple yet durable upgrade to your motorcycle's suspension system. Featuring a five-position cam-style spring preload adjuster, this shock allows riders to easily customize ride height and comfort to suit various riding conditions and preferences. Constructed in the USA, the 412 Series is built with high-quality materials to ensure longevity and consistent performance. Its versatile design is suitable for both street and occasional off-road use, with approval for road use confirmed through recent certification.
Installing these shocks on '86-'15 XL models might require modifications or spacers for the chain or belt guard to ensure proper clearance. The shocks are available in multiple styles, including full show-chrome or black covers, along with chrome or black springs and end caps, allowing you to match your bike's aesthetic. A slightly longer shock than stock can subtly alter the head angle, providing quicker steering, while a shorter shock can slow steering response. For bikes operated near maximum load capacity over half the time, Heavy Duty Applications are recommended to maintain optimal performance.
Before replacing OEM shocks with different lengths, it’s important to verify that wheel travel and clearance are sufficient to avoid contact with the exhaust, swingarm, axle, chain/belt guard, or tires. These shocks are measured from center-of-eyelet to center-of-eyelet, ensuring precise fitment. Whether you're looking to improve handling, ride comfort, or customize your Harley-Davidson, the Progressive Suspension 412 Series Shock provides a cost-effective and reliable upgrade to enhance your motorcycle's suspension performance.
