Progressive Suspension 412 Series Shock for Harley Models - 12 Inch Chrome with Cam-Style Preload Adjuster

Designed specifically for Harley-Davidson motorcycles, the Progressive Suspension 412 Series Shock offers a simple yet durable upgrade to improve your bike's suspension performance. With a 12-inch length, these shocks are tailored to enhance ride quality by providing better handling and comfort on various terrains. The shocks feature a five-position cam-style spring load preload adjuster, allowing you to easily customize the ride stiffness to suit your riding style and load conditions. Whether you're cruising city streets or tackling rugged trails, these shocks provide a versatile and cost-effective solution for suspension enhancement.
Constructed in the USA, the shocks are available with multiple style options, including full show-chrome or black covers, and either chrome or black springs and end caps. This variety allows you to match your motorcycle's aesthetic preferences while benefiting from improved suspension. The shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility with a wide range of Harley models, especially from 1986 to 2015 XL series. When installing on certain models, such as '86-'15 XL, modifications to the chain or belt guard may be necessary to ensure proper clearance.
Adjusting the ride height by selecting shocks slightly longer or shorter than stock can influence steering characteristics; longer shocks may provide quicker steering, while shorter shocks can result in a slightly slower turn-in response. For bikes subjected to maximum load conditions over 50% of the time, Heavy Duty applications are recommended to ensure durability and performance. Before installing shocks that differ from OEM length, verify that wheel travel and clearance are adequate to prevent contact issues with the swingarm, exhaust, chain/belt guard, or tires. Overall, the Progressive Suspension 412 Series Shock combines quality craftsmanship with customizable features to enhance your Harley-Davidson riding experience.
