Designed specifically for Harley-Davidson models, the Progressive Suspension 412 Series Shock offers a reliable upgrade to your motorcycle's suspension system. With a simple yet durable design, this shock absorber is an affordable solution to enhance ride comfort and handling. The shock features a five-position cam-style spring preload adjuster, allowing you to easily fine-tune the suspension to match your riding style and load conditions. This adjustability ensures a more personalized and comfortable ride, whether you're cruising on highways or tackling uneven terrain.
The 412 Series Shock is available in multiple styles, including full show-chrome or black covers, with either chrome or black springs and end caps, providing options to match your motorcycle's aesthetic. Made in the USA, these shocks are measured from center-of-eyelet to center-of-eyelet, ensuring accurate fitment for Harley models. Some shocks listed are approved for road use; please refer to the latest certification for current approval status. When installing shocks on '86-'15 XL models, modifications such as spacing the chain or belt guard might be necessary to ensure proper clearance. It's important to verify that your wheel travel can accommodate different shock lengths without causing contact issues with the swingarm, exhaust, or other components.
A slightly longer shock than stock can subtly alter the head angle, resulting in quicker steering, while a shorter shock may slow steering response. Heavy-duty applications are recommended for bikes operated near or at maximum load ratings over 50% of the time. Before purchasing or installing shocks that differ from OEM length, confirm that your motorcycle's clearance and travel capabilities are compatible to avoid contact issues with the chain, belt guard, or tires. This shock's robust design and adjustability make it an excellent choice for riders seeking improved suspension performance and personalized ride quality on Harley-Davidson motorcycles.
