The Progressive Suspension 412 Series Shock is designed specifically for Harley-Davidson models, offering a straightforward and durable upgrade to enhance your motorcycle's suspension performance. With a focus on affordability and reliability, these shocks are suitable for riders seeking a cost-effective way to improve ride quality and handling. The black finish provides a sleek, understated look that complements a variety of motorcycle styles while maintaining resilience against the elements. Constructed in the USA, these shocks are engineered for durability and long-lasting performance. They feature a five-position cam-style spring preload adjuster, allowing you to easily customize ride comfort and handling characteristics to match your riding style or load conditions. This adjustability makes it simple to dial in the optimal suspension setup without the need for additional tools or complex procedures. All shocks are measured from center of eyelet to center of eyelet, ensuring compatibility with your Harley bike. When installing on '86-'15 XL models, some modifications or spacers may be necessary to accommodate chain or belt guards for proper clearance. Slight variations in length—either longer or shorter than stock—can influence steering behavior, with longer shocks providing a quicker steering response and shorter shocks offering a more relaxed turn. These shocks are available in multiple styles, including full show-chrome, black covers, chrome springs, or black springs and end caps, allowing riders to customize their bike's aesthetic to match personal preferences. For bikes operated near or at the manufacturer's maximum load ratings over 50% of the time, Heavy Duty Applications are recommended to ensure optimal performance and durability. Before purchasing or installing shocks that differ from OEM length, it is important to verify that wheel travel and clearance are sufficient to prevent contact with exhaust, swingarm, axle, or tires. Overall, the Progressive Suspension 412 Series Shock provides a versatile, reliable upgrade that enhances ride quality, handling, and aesthetic appeal for Harley riders seeking durability and performance.
