Featuring the innovative Frequency Sensing Technology (FST), these shocks automatically adjust damping by sensing bump frequencies, ensuring a smooth and controlled ride across various terrains. The deflective disc valving provides precise damping response, contributing to stability and comfort during high-performance riding. A pre-load spring, adjustable by hand without tools, allows for quick setup adjustments to match rider preferences and load conditions. These shocks include a progressive-rate spring and are high-pressure gas charged, ensuring consistent performance and durability over time.\u003cbr\u003eMade in the USA, the shocks are slightly longer or shorter than stock options, which can influence steering characteristics—longer shocks may offer quicker steering, while shorter ones can result in slower response. It is essential to verify that wheel travel can be adjusted accordingly without causing clearance issues with components such as the swingarm, exhaust, chain or belt guard, or tires before installation. Designed for heavy-duty applications, these shocks are recommended for bikes operating at or near maximum load ratings more than 50% of the time, providing reliable performance under demanding conditions. Whether upgrading an existing suspension or customizing your motorcycle for specific performance needs, the Progressive Suspension 444 Series Shock offers a durable and adaptable solution for serious riders seeking superior handling and comfort.\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 and stable damping response\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePre-load spring: Easily adjustable by hand without special tools\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh-pressure gas charged: Ensures consistent performance over time\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes progressive-rate spring: Offers adaptable ride comfort and support\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\u003eDimensions: Slight variation from stock length to influence steering and handling characteristics\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty application suitability: Ideal for bikes operating near maximum load ratings for extended periods\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966983823557,"sku":"444-4019B","price":860.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/159652.png?v=1773697302","url":"https:\/\/btqllc.com\/products\/progressive-suspension-444-series-shock-12-5-inch-heavy-duty-black-part-444-4019b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
