This innovative feature ensures optimal shock performance across a variety of terrains by sensing the frequency of impacts and responding accordingly. The shock incorporates deflective disc valving, which provides precise control and consistent damping characteristics, contributing to improved handling and stability. Designed with a pre-load spring that can be adjusted by hand without special tools, this shock offers hassle-free customization to match rider weight and riding style. It includes a progressive-rate spring, which delivers a comfortable ride during normal riding conditions while increasing resistance during aggressive maneuvers or heavier loads, and is high-pressure gas charged for reliable, consistent performance. Made in the USA, this shock is slightly longer than stock which can subtly alter the head angle and offer quicker steering response, or slightly shorter which may slow steering response—always verify wheel travel and clearance before installation to prevent contact issues with exhaust, chain or belt guard, or tires. Intended for heavy-duty applications, it is recommended for motorcycles frequently operating near maximum load capacities, providing durability and support under demanding conditions. The durable black finish complements the rugged aesthetic of your motorcycle while ensuring long-term corrosion resistance. Whether upgrading for performance or replacing worn shocks, the PROGRESSIVE SUSPENSION 444 Series Shock offers a reliable solution for riders seeking enhanced handling, comfort, and 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 and consistent damping\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\u003eProgressive-rate spring: Ensures comfort during normal riding and increased resistance during aggressive maneuvers\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh-pressure gas charged: Maintains consistent performance over time\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA: Ensures quality and craftsmanship\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLength variations: Slightly longer or shorter than stock to alter steering response, verify wheel travel and clearance before installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty application: Suitable for bikes operating near maximum load capacity for extended periods\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966984413381,"sku":"444-4001B","price":860.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/159601.png?v=1773697345","url":"https:\/\/btqllc.com\/products\/progressive-suspension-444-series-shock-12-5-inches-standard-heavy-duty-by-progressive-suspension-part-444-4001b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
