The Progressive Suspension 412 Series Shock is designed specifically for Harley-Davidson models, offering a simple yet durable upgrade to enhance your motorcycle's suspension performance. Crafted with a focus on affordability and reliability, this shock improves ride quality by providing better shock absorption and handling characteristics. Its robust construction ensures longevity, making it a cost-effective enhancement for both daily riders and long-distance enthusiasts. The black or chrome covers, along with available chrome or black springs and end caps, allow for customization to match your bike’s aesthetic.
Featuring a five-position cam style spring load preload adjuster, the 412 Series shock enables riders to easily dial in the optimal ride height and firmness. This adjuster provides versatility for different riding conditions and load situations, ensuring a tailored ride experience. The shocks are measured from center-of-eyelet to center-of-eyelet, maintaining compatibility with a wide range of Harley models. When installing on '86-'15 XL models, some modifications or spacers may be required for the chain or belt guard to achieve proper clearance. It’s important to verify your wheel travel and clearance before installation, especially if considering shocks longer or shorter than the OEM specifications.
Slight variations in shock length can influence steering, with longer shocks offering a quicker turn response and shorter shocks providing a more relaxed steering feel. Heavy-duty applications are recommended for bikes frequently carrying maximum loads, ensuring durability under demanding conditions. Many of these shocks are approved for road use, with certification details available upon request. Made in the USA, the PROGRESSIVE SUSPENSION 412 series shocks are a reliable choice for enhancing ride comfort, handling, and style on Harley-Davidson motorcycles.
