Featuring advanced Frequency Sensing Technology (FST), these shocks automatically adjust damping by sensing the frequency of bumps for a smoother and more controlled ride. This innovative technology ensures optimal performance across varied terrains and riding conditions. Constructed with deflective disc valving, the shocks deliver precise damping control, reducing harshness and improving handling. They come equipped with a pre-load spring that can be adjusted manually without the need for special tools, allowing for quick customization to rider preferences and load conditions. The shocks include a progressive-rate spring and are high-pressure gas charged, ensuring consistent performance and longevity over time.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eFrequency Sensing Technology (FST): Automatically adjusts damping based on bump frequency for superior ride quality.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDeflective disc valving: Provides precise damping control for improved handling and comfort.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePre-load spring adjustment: Manual, tool-less pre-load adjustment for easy customization.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh-pressure gas charged: Ensures consistent performance and durability.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes progressive-rate spring: Enhances ride comfort and stability under load.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA: Quality manufacturing standards for reliability.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLength options: Slightly longer shocks may alter head angle and improve steering responsiveness; slightly shorter shocks may provide slower steering.
