Featuring the innovative Frequency Sensing Technology (FST), this shock automatically adjusts damping by sensing the frequency of bumps, resulting in a smoother and more controlled ride across various terrains. The deflective disc valving ensures precise damping control, enhancing stability and handling during aggressive riding or long-distance cruising. A pre-load spring is included and can be adjusted by hand without special tools, allowing for quick customization to your load and riding style. Constructed with a high-pressure gas-charged design, the shock maintains consistent performance and durability over time, even under demanding conditions. Made in the USA, this shock combines quality craftsmanship with advanced technology to deliver long-lasting reliability. The 13-inch length slightly alters the front-end geometry, which can improve steering responsiveness; however, before installation, confirm your wheel travel can accommodate the change without clearance issues such as exhaust contact or chain\/belt interference. For riders operating near or at maximum load ratings over 50% of the time, the heavy-duty construction provides the extra strength needed for demanding riding conditions. Whether you're replacing worn shocks or upgrading for performance, the Progressive Suspension 444 Series Shock offers a robust solution with easy adjustments and proven durability.\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 control over damping characteristics.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePre-load spring: Easily adjustable by hand without special tools to customize ride stiffness.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh-pressure gas charge: Ensures consistent performance and long-term reliability.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA: Quality craftsmanship and American manufacturing standards.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustable length: Slightly longer or shorter options may alter steering and head angle for better handling.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty design: Suitable for bikes operating at or near maximum load over half the time, ensuring durability under demanding conditions.\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":43031840915550,"sku":"13100789","price":783.47,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0012\/2545\/7758\/files\/159719.png?v=1784492660","url":"https:\/\/vtwinvisionary.com\/products\/progressive-suspension-444-series-shock-13-inch-heavy-duty-chrome-part-444-4051c","provider":"V-TwinVisionary","version":"1.0","type":"link"}
