Featuring advanced Frequency Sensing Technology (FST), these shocks can automatically adjust damping based on the frequency of bumps encountered, providing a smoother and more controlled ride. The FST system ensures optimal shock response whether you're tackling rough terrain or smooth highways, improving overall ride comfort and stability. Constructed with deflective disc valving, these shocks deliver precise damping control, reducing harshness and maintaining consistent performance across varying loads and conditions. The shocks include a progressive rate spring that can be manually adjusted for preload without the need for special tools, allowing for easy customization to match rider preferences and load requirements. They are high-pressure gas-charged, ensuring consistent damping performance over time and under heavy loads, making them ideal for heavy-duty use. If your motorcycle's shock length differs slightly from stock, this can influence the head angle and steering response, providing a marginally quicker or slower steering feel depending on the length adjustment. Heavy-duty applications are recommended for bikes operated near or at their maximum load capacity most of the time, ensuring longevity and reliable performance. Before installing shocks that differ from OEM length, verify that wheel travel can accommodate the change without causing clearance issues such as contact with swingarm, exhaust, chain or belt guards, or tires. Designed for durability and versatile performance, the Progressive Suspension 444-4250B shocks are a reliable upgrade for riders seeking enhanced handling and ride quality in demanding riding 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 superior ride quality\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDeflective disc valving: Provides precise damping control and consistent performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustable spring preload: Manually adjustable without special tools for customized ride comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh-pressure gas charge: Ensures consistent damping performance over time and under load\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes a progressive rate spring: Allows for enhanced ride comfort and load handling\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with slightly longer or shorter shock lengths: Alters head angle and steering response accordingly\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty design: Suitable for bikes operated near maximum load capacity most of the time\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eImportant installation note: Confirm wheel travel clearance when installing shocks with different lengths than OEM\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966979530949,"sku":"444-4250B","price":860.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/160196.png?v=1773697053","url":"https:\/\/btqllc.com\/products\/progressive-suspension-444-series-shock-12-inch-heavy-duty-black-part-number-444-4250b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
