Featuring the innovative Frequency Sensing Technology (FST), these shocks automatically adjust damping based on bump frequency, ensuring a smooth and controlled ride over diverse terrains. The deflective disc valving enhances responsiveness, providing precise control and comfort during aggressive riding or long-distance cruising. The preload spring can be adjusted manually without special tools, allowing customization to your specific load and riding style. Each shock includes a progressive-rate spring and is high-pressure gas charged, which contributes to consistent performance and reliable damping characteristics.\u003cbr\u003eMade in the USA, these shocks are designed for heavy-duty applications, making them suitable for bikes operating near or at maximum load capacity over 50% of the time. Slight modifications to the bike's head angle may occur if the shocks are longer or shorter than stock, which can affect steering response—longer shocks can provide quicker steering, while shorter shocks may result in slower steering. It is important to verify that your wheel travel allows for these modifications without causing clearance issues such as contact between the swingarm, axle, exhaust, chain or belt guard, or tires. Proper installation ensures optimal performance and longevity, making these shocks a reliable upgrade for demanding riding conditions.\u003cbr\u003eWhether you're enhancing your bike's handling or looking for robust shock absorbers for heavy-duty use, the Progressive Suspension 444 Series offers a high-quality solution with advanced damping technology and durable construction for a smooth, controlled ride.\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 responsiveness and control\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePreload spring: Easily adjustable by hand without special tools\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSpring type: Progressive-rate spring for adaptive performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eGas charging: High-pressure gas for consistent damping and performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA: Ensures quality and reliability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatibility note: Slight length variations may alter head angle and steering response\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eApplication suitability: Recommended for heavy-duty use and high load conditions\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966983921861,"sku":"444-4002B","price":860.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/159610.png?v=1773697330","url":"https:\/\/btqllc.com\/products\/progressive-suspension-444-series-shock-13-inch-standard-heavy-duty-black-part-no-444-4002b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
