The Progressive Suspension 412 Series Shock is designed specifically for Harley-Davidson models, offering a simple yet durable upgrade to your motorcycle's suspension system. Constructed with quality materials and a straightforward design, this shock absorber enhances ride comfort and handling without compromising on cost-effectiveness. Featuring a five-position cam-style spring preload adjuster, it allows riders to easily dial in their preferred ride height and firmness for optimal performance across various riding conditions.
Made in the USA, the 412 Series Shock is available with multiple style options including full show-chrome or black covers, and chrome or black springs and end caps to match your motorcycle’s aesthetic. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility and precise fitment. When installing on '86-'15 XL models, some modifications or spacing of the chain or belt guard may be necessary to achieve proper clearance.
This shock may be slightly longer or shorter than stock, which can subtly alter the head angle and affect steering response—either quicker or slower. Heavy-duty applications are recommended for bikes often operated at or near maximum load ratings. Before selecting shocks that differ from OEM length, verify that your wheel travel can be adjusted without causing clearance issues, such as contact between the swingarm, axle, exhaust, chain/belt guard, or tires. The 412 Series Shock provides a reliable, customizable upgrade for Harley owners seeking improved ride quality and handling.
