The Progressive Suspension 412 Series Shock, designed specifically for Harley-Davidson models, offers an affordable upgrade to enhance your motorcycle's suspension performance. With a durable and simple design, these shocks provide reliable handling and improved comfort on the road. The five-position cam-style spring preload adjuster allows you to easily customize ride stiffness, ensuring optimal performance for various riding conditions. Made in the USA, these shocks are built to last and are available in multiple style options, including full show-chrome or black covers, with either chrome or black springs and end caps for a personalized look.
All shocks are measured from center-of-eyelet to center-of-eyelet, making installation straightforward. When installing on '86-'15 XL models, you may need to modify or space the chain or belt guard to ensure proper clearance. Slight variations in shock length can affect steering dynamics: a longer shock may result in a slightly quicker steering response, while a shorter one could slow steering slightly. Heavy-duty applications are recommended for bikes operated near or at the maximum load rating over 50% of the time, providing added durability for demanding conditions.
Before purchasing or installing shocks that differ from OEM length, verify that your wheel travel can be adjusted without clearance issues such as contact with the swingarm, exhaust, chain or belt guard, or tires. Proper selection ensures optimal performance and safety, making the Progressive Suspension 412 Series Shock a dependable choice for motorcycle enthusiasts seeking a balance of performance, durability, and customization.
