The Progressive Suspension 444 Series Shock Absorber is designed to enhance the ride quality of your motorcycle with advanced features and durable construction. Featuring Frequency Sensing Technology (FST), these shocks automatically adjust damping based on the frequency of bumps encountered, providing a smoother and more controlled ride across various terrains. This innovative technology ensures optimal performance whether you're on uneven roads or smooth pavement, reducing rider fatigue and improving handling. The shocks are equipped with deflective disc valving that precisely manages fluid flow for consistent damping characteristics, contributing to improved stability and comfort during riding.
The included pre-load spring can be easily adjusted by hand without the need for special tools, allowing riders to customize their suspension setup quickly and effortlessly. With a progressive-rate spring, these shocks respond dynamically to different load conditions, offering a softer ride over small bumps and increased resistance during larger impacts. They are high-pressure gas charged, which maintains consistent damping performance over time and prevents fade during extended use. Made in the USA, these shocks are built to meet high standards of quality and durability.
Please note that the shocks are slightly longer than stock, which may alter your motorcycle’s head angle and provide quicker steering response. Conversely, shocks that are shorter than stock can slow steering but may affect clearance with components such as the swingarm, axle, exhaust, or tires. Before installation, it’s essential to verify that your wheel travel can be adjusted without causing contact issues with other parts of your motorcycle. These shocks are recommended for heavy-duty applications or bikes operating at or near maximum load capacity over 50% of the time, ensuring reliable performance under demanding conditions.
