Featuring advanced Frequency Sensing Technology (FST), these shocks automatically adjust damping based on bump frequency, ensuring a smoother and more controlled ride across various terrains. The deflective disc valving enhances shock responsiveness while the pre-load spring can be easily adjusted by hand without the need for special tools, allowing for quick customization to rider weight and riding conditions. Each shock includes a progressive-rate spring and is high-pressure gas charged to deliver consistent performance and improved handling. Made in the USA, these shocks are designed to provide durability and reliable performance under demanding conditions. Slightly longer than stock shocks, they may alter the head angle slightly, resulting in quicker steering response, whereas shorter shocks may slow steering and modify handling characteristics. It is important to verify that your wheel travel can accommodate a different shock length without causing clearance issues such as swingarm or axle contact with exhaust components or chain\/belt guards. These shocks are highly recommended for heavy-duty applications, especially for bikes that operate near maximum load ratings more than half of the time, ensuring durability and stability during rigorous riding. Installation and performance depend on proper selection based on your motorcycle's specifications and riding needs, making the Progressive Suspension 444 Series a reliable choice for enhancing motorcycle handling and comfort.\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: Enhances responsiveness and shock performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePre-load spring: Easily adjustable by hand without tools for quick customization\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eProgressive-rate spring: Provides a smooth initial motion with increased support as load increases\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\u003eMade in the USA: Quality manufacturing for reliable performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSlightly longer or shorter options: Alters head angle and steering response for customized handling\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty application suitability: Designed for bikes operating near maximum load more than 50% of the time\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966983495877,"sku":"444-4039B","price":860.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/159683.png?v=1773697245","url":"https:\/\/btqllc.com\/products\/progressive-suspension-444-series-shock-13-inch-standard-black-part-444-4039b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
