Featuring advanced Frequency Sensing Technology (FST), these shocks automatically adjust damping in response to bump frequency, ensuring a smoother and more controlled ride across various terrains. The deflective disc valving enhances shock responsiveness, while the pre-load spring is easily adjustable by hand, allowing quick customization without special tools. Constructed with a progressive-rate spring and high-pressure gas charging, these shocks deliver consistent performance and durability during demanding riding conditions.\u003c\/p\u003e\u003cp\u003eMade in the USA, the 13-inch shocks are slightly longer than stock, which may alter the head angle and provide quicker steering. Conversely, shorter shocks can slow steering and modify handling characteristics. Before installation, verify that your wheel travel can accommodate these length modifications without causing clearance issues such as contact with the exhaust, chain or belt guards, or tires. 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.\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 optimal ride quality\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDeflective disc valving enhances responsiveness and shock control\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePre-load spring is adjustable by hand without the need for special tools\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes a progressive-rate spring for smooth compression and rebound\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh-pressure gas charged for consistent, reliable performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA for quality assurance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSlightly longer shocks may alter head angle and improve steering response\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSuitable for heavy-duty motorcycle applications under maximum load conditions\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966983725253,"sku":"444-4020C","price":860.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/159662.png?v=1773697277","url":"https:\/\/btqllc.com\/products\/progressive-suspension-444-series-shock-13-inch-heavy-duty-chrome-part-444-4020c","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
