Featuring advanced Frequency Sensing Technology (FST), these shocks automatically adjust damping based on bump frequency, providing a smoother and more controlled ride across various terrains. The deflective disc valving ensures precise damping response, while the pre-load spring can be easily adjusted by hand without any special tools, allowing for quick customization to match rider weight and riding conditions. Each shock includes a progressive-rate spring and is high-pressure gas charged for consistent performance and durability, making it ideal for demanding riding scenarios. Made in the USA, these shocks are slightly longer than stock models, which may alter the head angle for quicker steering, or slightly shorter, which could result in slower steering; it is important to verify that your wheel travel can accommodate these modifications without clearance issues such as swingarm or axle contact with exhaust components, chain or belt guards, or tires. Designed for bikes operating at or near maximum load ratings over 50% of the time, the Progressive Suspension 444 Series shocks deliver reliable performance, improved handling, and a smoother ride under heavy load conditions, making them a dependable upgrade for serious riders seeking durability and enhanced ride quality.\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 response for a smoother ride\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePre-load spring: Easily adjustable by hand without special tools for quick ride customization\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eProgressive-rate spring: Ensures consistent performance and shock absorption\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHigh-pressure gas charged: Enhances durability and ride consistency\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA: Quality craftsmanship and reliable performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eLength variations: Slightly longer or shorter than stock to alter steering characteristics\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eApplication considerations: Verify wheel travel and clearance to prevent contact issues\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty application suitability: Designed for bikes operating at or near maximum load over 50% of the time\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":43031866343518,"sku":"13100766","price":783.47,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0012\/2545\/7758\/files\/159655.png?v=1784494016","url":"https:\/\/vtwinvisionary.com\/products\/progressive-suspension-444-series-shock-12-5-inch-heavy-duty-chrome-part-number-444-4019c","provider":"V-TwinVisionary","version":"1.0","type":"link"}
