Incorporating the innovative Frequency Sensing Technology (FST), these shocks automatically adjust damping based on the frequency of bumps encountered, ensuring a smoother and more controlled ride across various terrains. The deflective disc valving further contributes to consistent damping performance, providing stability and comfort during aggressive riding or long-distance cruising. The preload spring can be easily adjusted by hand without any special tools, allowing for quick customization to suit rider weight or riding conditions. Additionally, the shocks include a progressive-rate spring, which adapts to different load conditions for superior support and comfort. These shocks are high-pressure gas charged, delivering consistent performance over time and reducing fade during prolonged use. Made in the USA, the 444 series shocks are slightly longer than stock, which may alter your bike's head angle and improve steering responsiveness, making them ideal for riders seeking quick handling. Conversely, shorter models are available to slightly slow steering and modify handling characteristics. Before installing shocks that differ from OEM length, ensure your wheel travel can be adjusted without interference with components like the swingarm, exhaust, chain or belt guard, or tires. These shocks are recommended for heavy-duty applications, especially for bikes operating near or at maximum load capacity over half the time, providing the durability and performance required for demanding riding conditions.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eFrequency Sensing Technology (FST): Adjusts damping automatically based on bump frequency for superior ride quality\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDeflective disc valving: Ensures consistent damping performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePreload spring: Easily adjustable by hand without special tools\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eProgressive-rate spring: Provides adaptable support for varying loads\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh-pressure gas charged: Maintains consistent performance over time\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA: Quality manufacturing and craftsmanship\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLength variation: Slightly longer or shorter than stock to modify steering and handling\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty application suitability: Designed for bikes operating at or near maximum load capacity\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966974255301,"sku":"444-4003B","price":860.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/159872.png?v=1773696732","url":"https:\/\/btqllc.com\/products\/progressive-suspension-444-series-shock-13-5-inch-heavy-duty-black-part-444-4003b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
