Progressive Suspension 412 Series Shock - 12.5 Inch Standard Chrome for Harley-Davidson 412-4001C

The Progressive Suspension 412 Series Shock, designed specifically for Harley-Davidson models, offers a simple yet durable upgrade to enhance your motorcycle's suspension performance. Engineered with a five-position cam-style spring preload adjuster, this shock allows riders to easily customize ride height and firmness, ensuring a tailored riding experience. Its robust construction and straightforward design make it a cost-effective solution for riders seeking improved handling and comfort. Made in the USA, the 412 Series Shock combines quality craftsmanship with functional performance, making it a popular choice among Harley enthusiasts.
This shock is suitable for a variety of Harley models, with some variations approved for road use. It is available in multiple style options, including full show-chrome or black covers, and chrome or black springs and end caps, allowing riders to match their bike’s aesthetic preferences. The shock's measurement from center-of-eyelet to center-of-eyelet ensures compatibility with your motorcycle's suspension setup. When installing on '86-'15 XL models, some modifications such as spacers may be necessary for proper clearance, particularly around the chain or belt guard.
Slight length variations from stock can influence steering characteristics; a longer shock may result in quicker steering, while a shorter one could provide a more relaxed feel. Heavy-duty applications are recommended for bikes frequently operated near maximum load ratings, ensuring durability and performance under demanding conditions. Before installing shocks that differ from OEM length, verify that wheel travel and clearance are sufficient to prevent contact issues with exhaust, swingarm, axle, or tires. Overall, the Progressive Suspension 412 Series Shock is an excellent upgrade for riders seeking improved suspension quality, ride comfort, and customization options.
