Featuring the innovative Frequency Sensing Technology (FST), these shocks can automatically adjust damping by sensing the frequency of bumps, providing a smoother riding experience across diverse terrain. Constructed with deflective disc valving, they ensure consistent damping response, while the pre-load spring can be easily adjusted by hand without any tools, allowing for quick customization to rider preference and load conditions. Equipped with a progressive-rate spring and high-pressure gas charging, these shocks deliver reliable and consistent performance even under demanding riding conditions. Made in the USA, the 444 Series shocks are designed to fit standard applications, with slight variations in length that may influence head angle and steering characteristics. Longer shocks could result in quicker steering, while shorter ones may slow steering response. It is essential to verify that your wheel travel and clearance are compatible with shocks that differ from OEM length to avoid issues such as contact with exhaust components, chain or belt guards, or tires. These shocks are especially suitable for heavy-duty applications, where riders operate at or near maximum load ratings for extended periods, ensuring durability and sustained performance over time.\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 comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDeflective disc valving: Ensures consistent damping response for a smooth ride\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 smooth compression and rebound characteristics\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh-pressure gas charged: Maintains performance consistency under demanding conditions\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 variations: Slightly longer or shorter than stock may alter steering response and head angle\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eApplication suitability: Designed for heavy-duty use and high load conditions\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":50007772037360,"sku":"13100777","price":860.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/1980\/5424\/files\/159683.png?v=1783696067","url":"https:\/\/sublimepowersports.com\/products\/progressive-suspension-444-series-shock-13-inch-standard-black-part-number-444-4039b","provider":"Sublime Powersports","version":"1.0","type":"link"}
