The shocks are equipped with deflective disc valving for precise control and performance. Their pre-load spring can be adjusted by hand without the need for special tools, making setup quick and convenient. These shocks include a progressive-rate spring designed to handle varying loads efficiently and are charged with high-pressure gas to ensure consistent damping performance over time. Constructed in the USA, these shocks are designed to enhance handling and ride quality, especially on bikes operating under heavy loads or near maximum capacity. Slightly longer than stock shocks, they can subtly alter the head angle, offering quicker steering response, while shorter variants can provide slower steering characteristics. It is important to verify that altering the shock length won't cause clearance issues with components such as the swingarm, exhaust, or tires before installation. Heavy-duty applications are recommended for motorcycles that frequently carry or operate near their maximum load capacity, ensuring durability and sustained performance under demanding conditions.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eFrequency Sensing Technology (FST): Automatically adjusts damping for superior ride comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDeflective disc valving: Ensures precise damping control\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePre-load spring: Easily adjustable by hand without tools\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eProgressive-rate spring: Handles varying loads effectively\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh-pressure gas charged: Maintains consistent performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA: Quality craftsmanship and durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRide height options: Slightly longer or shorter shocks to modify steering response\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty suitability: Ideal for bikes operating at or near maximum load capacity\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":50007772004592,"sku":"13100788","price":860.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/1980\/5424\/files\/159716.png?v=1783696062","url":"https:\/\/sublimepowersports.com\/products\/progressive-suspension-444-series-shock-13-inch-heavy-duty-black-part-number-444-4051b","provider":"Sublime Powersports","version":"1.0","type":"link"}
