The Progressive Suspension 412 Series Shock Absorber, designed specifically for Harley-Davidson models, provides a cost-effective upgrade to enhance your motorcycle's suspension performance. Crafted with simplicity and durability in mind, this shock features a five-position cam-style spring preload adjuster, allowing riders to easily tune the ride quality to their preference. Whether you're seeking a firmer or softer suspension setting, the adjustable preload ensures a tailored riding experience. Made in the USA, the 412 series shocks are built to exacting standards, ensuring long-lasting performance and reliability across various riding conditions.
Available in multiple styles, including full show-chrome, black covers, chrome springs, or black springs with end caps, these shocks offer versatile aesthetics to match your bike's look. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility and ease of installation. When installing on '86-'15 XL models, some modifications to the chain or belt guard may be necessary to ensure proper clearance. Slight length variations compared to stock shocks can influence the head angle, providing quicker or slower steering responses depending on whether they are longer or shorter than the original components. Heavy-duty applications are recommended for bikes frequently operated near the maximum load capacity, ensuring stability and durability during demanding rides.
Before purchasing or installing shocks that differ from OEM length, please verify that wheel travel can be adjusted without causing clearance issues such as swingarm or axle contact, exhaust interference, or chain/belt guard conflicts. This proactive check helps maintain optimal handling and safety. The PROGRESSIVE SUSPENSION 412-4008C shocks are an excellent choice for riders seeking improved comfort, performance, and style, offering a reliable upgrade without compromising ride quality.
